Electric blanket for Japanese winter bedding

By | Japanese House, Life in Japan, Property

The fun Christmas season of December is approaching. Japan is about to enter the winter season in earnest.
“Warm even in winter” is the most important factor in assessing the value of a home.

However, for foreigners, Japanese housing has the problem that it is very cold in winter. It feels cold not only for foreigners from hot Southeast Asian countries but also for foreigners from cold regions such as North America and Europe.
I spent my high school days in Hokkaido, and although it was cold outdoors, the inside of the building didn’t feel as cold as Osaka or Tokyo.

Most Japanese rental apartments do not contain the heat insulating material that should be put in the interior floor, wall, and ceiling in order to reduce the construction cost. The rental apartments where heat insulating materials are firmly installed on the floor, walls, and ceiling are very different from rental apartments where heat insulating materials are not installed. The comfort of living differs entirely.

Most of the general owners and lessees do not have any knowledge about this. In fact, there are many cases where construction companies skip the work process of adding heat insulating material to make construction easier.

In the case of detached houses, there are many properties where the underfloor on the first floor is left as soil. The old houses were still soil, and wooden houses were built on the soil. Therefore, turning the floorboard is the same as the soil like the field.

You can prevent the cold to some extent by pouring concrete over this soil to make it a “solid foundation”. At the cost of construction, the underfloor of a wooden detached house can be made of concrete.

But concrete is still cold in winter (and hot in summer).

Since the building is also made of concrete, when the concrete gets cold in winter, the room inevitably gets cold. Depending on the property, it might be warmer outside the apartment building in winter than inside the apartment building. This is because the concrete of the building’s frame gets cold.

Therefore, what is important is a heater that heats the air such as an air conditioner and “bedding”.

Please check the followings in order to make your bedding warmer for Japanese winter.

(1) Double the comforters.
The comforters we provide are ① one summer comforter and ➁ one spring / autumn comforter. Please snap ①summer comforter on ➁spring/ autumn comforter.  Then a winter comforter could be made. After doubling it, put the comforter cover on it in one piece.

(3) Change the comforter cover from sheets to a blanket cover

(4) Add another blanket to the mattress

(5) Change the blanket of the mattress to an “electric blanket”

My recommendation is No.(5) electric blanket.
I love this electric blanket.
I have never felt that an electric blanket is bad for my body.
It is warm and makes people to sleep longer. The reason why people can’t sleep in winter is often due to the cold temperature. You can sleep well if the bedding is warm.
If you use an electric blanket, you will not want to get out of bed because it is warm and too comfortable inside the bed.

With an electric blanket, the winter bedding problem is completely solved.

Japanese Precious Wood of Mt. Yoshino, Nara Prefecture

By | Interior Coordinate, Japan Culture, Real Estate

This month we visited several timber-related businesses near the Yoshino River in Nara Prefecture.

The Yoshino River flows through the center of Nara Prefecture and the northern part of Wakayama Prefecture to the sea, but there are many lumber and furniture processing industries along this river. Geographically, I think the Yoshino River was used to transport trees cut down from Mt. Yoshino and the mountains of Wakayama Prefecture. It is believed that the lumber-related business has a long history.

We drove on the narrow and rough road of Mt. Yoshino and visited Tokuda Meiboku Co., Ltd in Kurotaki Village. When I called Tokuda office in advance, the lady staff kindly accepted our visit, saying, “Yes, please, please come on !.”

When I entered the building of Tokuda Meiboku, I was surprised to see a huge number of natural trees lined up. There are many companies in this area who are engaged in forestry and lumber industry, but they did not do the same thing, and they seemed to be different. Above all, the president of Tokuda Meiboku Co. Ltd has a management strategy that treats natural wood in a dignified manner, and I think it deserves special mention.

I think most of the people who visited Tokuda Meiboku will be surprised by the size and quality of the wood, but I was different from other people. Rather than the splendor of the wood, the natural wood, which is said to have 30,000 different shapes, was properly labeled with numbers in the warehouse and kept in order. I was impressed by the fact that Mr. Tokuda has a very high management ability. I think that the internal control of accounting is also excellent.

I completely liked it. Since I came all the long way to the mountains, I bought as much of this company’s trees as I could put in my car. I would like to make a dining table or shelf using these wood. Tokuda Meiboku Co.Ltd is a forestry, so they will cut good quality cedar and cypress from the mountains. What you do with the tree depends on the creativity of the buyer. It seems that there are also artists. Depending on the creativity of the purchaser, I think that the range of use of natural wood, “how to utilize it,” has great potential.

Wao!? Is this a product?!!

What is Guarantor Company (Hosho Gaisya)?

By | Real Estate

(Photo: GTN Corporation’s application form)

By Masahiro Fukai, Dios Co.,Ltd

I will explain about the guarantor company. The guarantor and the guarantor company are different. Both guarantee rent, but it is common for the landlord to require both a guarantor and a guarantor company. If you have a guarantor, you may think that you do not need a guarantor company, but the guarantor company may request a guarantor during their examination process.

It’s complicated and difficult to understand, isn’t it?

As for the guarantor company, when the Lessee is behind in rent, the guarantor company first reimburses the rent to the owner. After that, the guarantor company collects the rent from the Lessee. Some guarantor companies have advertised that they guarantee rent for 12 or even 24 months. This gives the owner peace of mind. Therefore, most modern rental housing owners require a guarantor company to join for their lease contract. And, in the contract with the guarantor company, the borrower has to pay about half a month’s rent to the guarantor company.

Why does the Lessee have to pay the guarantor company half a month’s rent? Some people say, “I wish the owner would pay for it.”

Until around 2000, there was no guarantor company system in Japan. Until then, the security deposit (Shikikin) was 6 to 10 months. Foreigners were surprised at the large initial cost of Japan.

Actually, this was also unavoidable. Under Japanese law, even if Lessee delinquently pays his rent, it is difficult to kick out the Lessee. It takes about 6 to 10 months to kick out the Lessee who does not pay the rent. Therefore, a security deposit was required for 6 to 10 months.

However, if the security deposit was 6 to 10 months, it would be too burdensome for the Lessee. A security deposit is a deposit that puts your money to sleep and you will not be able to drive cash while you are living in the apartment. On the other hand, if the owner also lacks cash flow, the owner may not be able to refund a large security deposit when Lessee moves out.

Therefore, the “Guarantor company” was introduced around 2000 in Japan.

The borrower pays the security deposit to the owner for about a month. Recently, the number of properties with a security deposit of 0 yen has increased. Instead, you pay the guarantor about half a month’s rent. Comparing paying the security deposit for 6 to 10 months and paying the guarantor fee for half a month of rent, it is lighter to pay the guarantor company for half a month.

Thus, from around 2000, guarantor companies became widespread in Japanese rental contracts.

[Real Estate Agent] This is an agent that serves as the landlord’s agent for
renting housing and that buys and sells real estate.
[Guarantor] This is a person who pays unpaid rent or unpaid repair
costs after you vacate rental housing when you do not/
cannot make the payment yourself. A guarantor is required
when applying to rent rental housing. Guarantors must

Kanto Region and is usually 1 or 2 months rent. Key
money is not returned. Recently there is some rental
housing that does not require key money to rent.
[Rent] This is the charge for renting the housing, and generally
the rent for the current month is due at the end of the

[Rent Liability Guarantee Company]
A rent liability guarantee company is a company that
guarantees to pay the rent to the landlord in the event that

month’s rent paid in advance as the guarantee fee for 2
years). However, this is not insurance. The guarantee
company will bill you for the rent that it paid for you.You

The asset value of Japanese buildings is zero

By | Japanese House

Japanese wooden houses will have zero value in 30 years. No, it is not zero, and the cost of demolishing the building is 5 million yen, so the value of the building will be minus 5 million yen, and the value of the land alone will remain. Even if the remodeling work is added, the value of minus 5 million yen will not change.

Whether it’s a new wooden house or a new apartment, the price drops by 20% the moment you buy it. This is because the price of a new building is not the market price, but the price decided by the developer. Since the new construction will be used from the day after the purchase, the price will be decided in the competition of the real estate market, so it will be the purchase price x 80%. Since then, building prices have fallen steadily in Japan.

Even if you spend millions of dollars on a home remodeling, the value remains zero, diminishing the motivation for the owner to invest in the home remodeling in their building. Therefore, DIY is not popular in Japan. And it is not possible to establish a home improvement store that has a wide variety of products for DIY. The value of a building is calculated simply by its “age”. I think the Japanese real estate appraisal standards are significantly distorting the Japanese real estate market. Also, proper inspection that supports real estate appraisal is important, but not. And there is no legal certificate to show that the housing equipment has been renewed.

In the American real estate market, where you can buy a pre-owned home for 30 million yen, live for 10 years, renovate for 2 million yen, and sell it for 32 million yen 10 years later, the owner will spend zero on the home. Become. On the other hand, in Japan, if the value of a new house of 30 million yen becomes zero, you will have to spend 30 million yen for each move, and if you move three times in your life, you will have to pay 30 million yen. Yen x 3 times = 90 million yen will be spent. In a country where housing expenses are zero and in a country where housing expenses are 90 million yen, the level of pressure on households is completely different.

Every country in the world has its own housing policy. I think that the idea that “disposable” is good is flowing in the basis of Japanese housing policy. The national housing policy stipulates the law, distorts the appraisal, and as a result, the DIY of existing homes is locked out, and in fact the housing becomes increasingly poor, so the appraisal falls again and finally the value of Japanese buildings Has fallen below zero.

In Japan today, interest rates are so low that you cannot spend your old age on interest alone. I think this is the cause of the anxiety of the Japanese people. Whether or not a real estate building becomes an asset should be regarded as an important political issue in Japan. I would like to analyze and clarify why Japanese housing is not an asset.

DIY and Japan-Vested interests and affiliates of contractors

By | Japanese House

The Japanese Architects Law is a national qualification enacted in 1950, and there are first-class architects, second-class architects, and wooden architects. In Japan, if you want to build a new wooden building with a total floor area of ​​more than 100 square meters, you must be a first-class architect, a second-class architect, or a wooden architect to design and supervise the construction.

Furthermore, when you ask a Japanese building material manufacturer for a product, most manufacturers say, “We can only sell it through a contractor.” As a result, ordinary consumers have less opportunity to purchase building materials directly. Building materials can be purchased at large home center such as Kohnan etc, but they are called “Pro shop” and are purchased by contractors, and the general public only has very small building materials such as shelves in Japan.

In the United States, it seems that even beams are sold at home centers. In other words, ordinary people who are not contractors can build their own homes by going to a home center for DIY. Some Americans think that even in foundation work, they can DIY with the advice of an expert, but in Japan that is completely unthinkable.

Before the Act on Architects of 1950 was enacted, carpenters did all the design and construction in Japan. I also doubt that design and construction are separate. I don’t think people who have never done construction can make a good design with just the paper on the desk. Besides, if I’m just constructing something designed by others, I don’t think the work is interesting. I think that the joy of making things should be done by the same person in both design and construction. It can be imagined that the old carpenter who was in charge of design and construction at the same time was doing creative and fun work.

I think that the Japanese Architects Law works to protect the vested interests of contractors in the name of protecting the safety of consumers. In addition, building material manufacturers and contractors seem to be affiliated and organized.

The average Japanese has a high hurdle to build their own house with DIY, and it is hard to reach, so it is unavoidable to ask a contractor to do the construction. The higher the quote of the contractor, the slower the maintenance of the building. In Japanese real estate, only land is valuable, and buildings lose their value over time. Japanese buildings are not assets. It has become clear that the cause lies in the vested interests of the Japanese construction companies mentioned above.

Construction of insulation wall

By | Japanese House

I have been introduced many properties to customers through the real estate brokerage business for over 20 years, but I did not know about “insulation”. However, by doing the wall insulation work by myself, I understood ​​what insulation is. Then, the actual conditions of heat insulation of Japanese houses became clear.

I am ashamed to say that I have not been able to correctly explain such important points to customers and provide real estate property information.

If the apartment is made of reinforced concrete, it will be very cold this winter season if it is not insulated. On the other hand, in summer, the room gets hot like a burning hell. Therefore, the air conditioner is fully rotated to adjust the room temperature. Even if you operate the air conditioner, the sensible temperature in winter changes greatly depending on the presence or absence of heat insulation.

If you do DIY construction on your house, I think that you will install insulation nearly 100% of the time. If you ask a contractor to do insulation work, it will be expensive, so if you rent a house you own to another person or sell it for sale, you will not do insulation work. Insulation construction is a tedious task for a contractor, and for rental apartment owners, the insulation work is simplified because they want to keep construction costs down.

First, studs are erected on the wall to make the wall vertical and flat. The studs are filled with foamed styrofoam or kanelite foam to a thickness of 15 mm to prevent condensation. These insulations are pressed against the concrete wall to secure it, without creating any gaps in the concrete wall. Completely cover the concrete wall with airtight tape to keep air out of the wall.

Then fill it with 50mm glass wool. In this way, I don’t think anyone has done the heat insulation construction of Styrofoam + glass wool, but I think it is a very effective construction method to prevent dew condensation.

The walls are completely airtight to prevent humid air from entering. I think this will prevent condensation even with glass wool.

Cover the glass wool with a moisture-proof sheet and secure it to the surface of the studs with an air tacker. Stick a soundproof sheet on top of it, and then screw the gypsum board onto it.

It seems that many construction shops do not want to do glass wool because it is vulnerable to condensation, but I think that it is a very good heat insulating material if it is installed correctly.

A solid insulation wall has been created.

The reality of Japanese architectural construction

By | Japanese House

Today, January 17th, is 26 years after the Great Hanshin-Awaji Earthquake, January 17, 1995. I also experienced this big earthquake at my home in Osaka. This quake was the biggest quake in my life.

On January 17th of this earthquake, a concrete pillar on the Hanshin Expressway broke and rolled over.

I recently noticed when I was doing skeleton remodeling work on a Japanese apartment. It is the fact that various things that are completely unrelated to concrete are mixed in concrete. I discovered Styrofoam.

This fact is not often pointed out, I think that the reason why the concrete pillar of the Hanshin Expressway broke was that something other than concrete was mixed in the concrete.

There is a lot of “garbage” in the concrete of Japanese apartments and public buildings.

Then, the reason why “garbage” is contained in concrete is to reduce the amount of concrete. In other words, to reduce the cost of construction.

It is unlikely that Japanese ordinary person like me does DIY concrete work. As a result, such information is not known to the general public. In the case of apartments, the concrete part is not seen by the consumer. Moreover, I don’t think there are any general consumers who cut concrete and look inside the concrete.

Japanese housing is undergoing a great deal of shoddy construction work where the general consumer cannot see it. In this blog, based on my actual experience at my own site, I will clarify the reality of how Japanese housing is constructed, what materials are used, what problems there are.

Customer’s “amulet”

By | Real Estate

Our customers have forgotten their “amulets” and returned to his home country, so we have considered an appropriate disposal method for “amulets”.


First of all, for the first six months, we offered our customers’ amulets to the Kamidana in our Dios head office in Nakanoshima Osaka.

On New Year’s Day, January 1, 2021, we visited Shitennoji Temple in Osaka for the practice of visiting a temple at the beginning of the New Year. Therefore, we prayed for the patronage of our customers in the temple, and at the same time, we put all of our customers’ amulets in the disposal box of the amulets at Shitennoji Temple.

Shitennoji is the first temple in Japan where Buddhism was introduced 1400 years ago. We participated in the monthly zazen meditation at this temple from 5 am. At this venerable Buddhist temple in Japan, we have properly disposed of our customers’ amulets.

On the same day, Dios bought a new “amulet” at Shitennoji Temple. This “amulet” is (1) the good relation with a Buddha and (2) the relation with a person. We love this new amulet very much. We will continue to raise it to our Kamidana of our Dios head office.

How to build a new internet connection to your home

By | Electric Appliance

To install a new internet in your home, first select an internet service provider, complete the procedure, and then set up your machine. This sequence of tasks is more complicated than you might think, and can be confusing if you don’t see the steps very accurately. The person who manages the procedure must have all the information.

Yodobashi Camera has a counter called “Consultation anything about the Internet”. Other consumer electronics retailers have similar consultation desks. It is recommended that the contractor himself or herself go there. If you are a foreigner, please go to this consultation desk with an interpreter who understands Japanese. Since “identity verification” is required for the contract procedure for the Internet, the contractor must bring his / her identification card and go directly to the consultation desk.

In the case of NTT FLET’S Hikari, you can make a contract by telephone. However, if you want to compare the price with other internet service providers, you need to go to the internet consultation desk of the electronics retail store.

(1) NTT FLET’S Hikari

(2) au Hikari

(3) eo Hikari


(5) Softbank

(6) docomo

(7) UQ WiMAX

(8) Y! mobile

Select from these (1) to (8) Internet service providers.

If the line is not laid in the house, NTT FLET’S Hikari will pull the line from the utility pole on the road, so it is unlikely that NTT FLET’S Hikari cannot be connected. However, NTT FLET’S Hikari is more expensive than other Internet carriers.

Softbank Hikari, docomo Hikari, and Biglobe Hikari use NTT’s internet connection. However, it is a little cheaper than NTT FLET’S Hikari.

“Au Hikari” tends to be strong in apartments, and “eo Hikari” tends to be strong in detached houses.

Also, if the mobile phone company you already have is au, Softbak, or docomo, if you sign up for a residential internet connection with the same company, you will get a package contract, and the monthly payment will be about 500 to 1,000 yen cheaper.

In order to complete the contract procedure at the “Internet consultation desk” such as Yodobashi Camera, you must exchange a lot of documents such as explanations of important matters. The contractor and the interpreter must be present at the contract procedure during that time. The paperwork can sometimes take several hours.

Also, if the documents are incomplete, you will have to go to the counter again, which is a little annoying. Therefore, please proceed with the procedure accurately, confirming and reconfirming, and carefully.

As for the wireless router, a mesh router is recommended to send the Internet radio waves over a wide area in a large house. One way is to install a relay machine. Consumer electronics retailers such as Yodobashi have the latest models, and there are various models from expensive to inexpensive.

First of all, please go to the “Internet consultation” counter of home electronics retailers such as Yodobashi.

Geo Tower Tenroku  (About Tenjinbashisuji 6-chome area)

By | Regionality

“Geo Tower Tenroku” is located at the intersection of Tenjinbashisuji 6-chome and is directly connected to the subway station. This station (station name “Tenjinbashisuji 6-chome”) is a station that can be used along the Sakaisuji subway line, the Tanimachi subway line, and the Hankyu Kyoto line and Hankyu Senri line. The apartment called “Geo Tower Tenroku” is very convenient for those who commute to stations along the Sakaisuji Line and Tanimachi Line. It is a very convenient place as it is connected to Higashi-Umeda Station, which is the most downtown area in Kansai and Osaka.

Even though Osaka Station and Namba Station are directly connected to the nearest station, their terminal buildings at the station are too large, so you actually have to walk a lot. On the other hand, “Geo Tower Tenroku” is only a 10m walk to the entrance of the station.

For shopping, there is “Hankyu Oasis” on the first floor of the same building of “Geo Tower Tenroku”. Hankyu Oasis is a grocery supermarket with a wide selection of high-quality products such as vegetables and meat.

In addition, Tenjinbashisuji Shopping Street is right in front of “Geo Tower Tenroku”. This Tenjinbashisuji shopping street is one of the most famous shopping streets in Osaka. The shopping mall is about 2 kilometers long and is lined with a wide variety of shops. From Tenjinbashi 6-chome Station, beyond JR Temma Station and Minamimorimachi Station, it is one of the busiest shopping streets in Osaka. There are many popular shops, and you can shop cheaply. Compared to Umeda and Namba, you can shop more closely to your life.

Tenjinbashi 6-chome is a traffic intersection where many people gather. Nevertheless, security is a good place. Namba and Umeda are okay as long as they are on the premises of a large-scale building, but there are night towns where people can drink alcohol, and depending on the area, it may be unsafe. As a residence, Tenjinbashi 6-chome is a convenient and safe place for residents’ everyday life.
