Expo Osaka 2025

As Japan embraces the season of autumn leaves, Kyoto’s foliage stands out in its stunning beauty. I encourage everyone visiting Japan to witness the magnificent autumn colors in Kyoto.

In the midst of this natural splendor, political discussions in Japan, particularly regarding Expo 2025, seem trivial and misplaced in the national parliament. The media and various pundits engage in fruitless debates, missing the mark with both liberal and conservative arguments.

However, amidst these discussions, my recent interactions with some young foreign professionals involved in the Expo pavilions were deeply inspiring. Their logical thinking, earnestness, sincerity, honesty, humility, grace, kindness, charming smiles, impeccable appearance, openness, and striking presence truly impressed me. These remarkable young individuals are a testament to the potential and brilliance that the Expo 2025 brings to Japan, warranting a grand celebration of this event.

These young adults, hailing from diverse backgrounds and nations, embody the essence of diversity. Their presence is a breeding ground for new ideas and perspectives, infusing the Expo with fresh energy and innovative thoughts.

Indeed, the youth possess a unique charm, bringing new ideas and vitality, often offering fresh and innovative perspectives. These young individuals are treasures of humanity, potentially the new leaders of our future generations.

The discussion surrounding Expo 2025 should not just focus on ‘what’ to do, but ‘who’ we are doing it with. It’s about collaborating with these vibrant young minds from around the world, harnessing their potential to create a memorable and impactful Expo.

The photo featured here was taken at my construction site in Sakurajima, where I am working as a carpenter. Purchasing building materials and transporting them to the site is a laborious task. Reducing the distance even by 10 meters significantly eases the burden of carrying heavy loads.

To facilitate this, we try to bring the material-laden trucks as close to the site as possible. As you can see in the photo, there is a wide road in front of my construction site, which is immensely helpful.

Contrastingly, the situation at the Expo venue in Yumeshima is quite different. The roads there are yet to be fully developed. Moreover, essential infrastructure like sewage pipes appears to be still in the process of being laid out. Since sewage pipes are typically buried under the roads, paving cannot commence until this pipework is complete. Transporting heavy construction materials over an unpaved, uneven surface would be extremely challenging.

Therefore, it’s not just construction work that’s lagging behind at Yumeshima but the creation of an environment conducive to construction activities. The lack of proper infrastructure significantly impacts the pace and efficiency of building work, a challenge we fortunately do not face at our well-equipped Sakurajima site.

The Expo meeting has concluded. The photograph attached was kindly shared by one of our international participants from the Expo pavilion. Today, Osaka experienced a sudden drop in temperature, making it a particularly cold day.

Despite the chilly weather, I felt a heartwarming sense of warmth and camaraderie from our European counterparts. Their kindness and warmth in these colder times were truly appreciated.

This morning, a photograph from the Expo Association captured a memorable moment that I recently had the privilege of experiencing. I met with representatives from various countries responsible for their respective Expo participation.

The impression they left was indelible: each one of them was exceptionally talented, earnest, and an exemplary figure of youth. Their collective brilliance left a lasting mark on me. Despite any potential gaps in our preparations on the Japanese side, I am wholeheartedly convinced that when such outstanding individuals from across the globe come together, pooling their diverse wisdom and insights, we can surely surmount even the most challenging of obstacles.

It’s a powerful reminder of the extraordinary potential that collaborative efforts hold on an international scale. Together, united in our diversity and shared goals, we can pave the way for meaningful progress and solutions.

Recent reports indicate that Mexico 🇲🇽 has communicated its decision to withdraw from the Osaka Expo, stepping back from their planned construction of a TYPE-A pavilion. This development raises questions about the support and response of the Japanese Organizing Committee to participating countries.

If I were a member of the Japanese Organizing Committee, this would be my approach to engage and support our international participants:

1. “What challenges are you currently facing?”
2. “Is it a matter of interpretation, budget constraints, technical issues, or design?”
3. “If there are difficulties, let’s collaboratively work towards solving them as Japan, the host nation.”
4. “We, as the host, are fully committed to supporting the construction and participation of your pavilion.”

I firmly believe that a host country, armed with a warm and compassionate approach, can pave the way towards resolving such issues. Embracing our guests from abroad with understanding and support is essential to foster strong international relationships and successful global events.

I am compelled to share profound insights from Emeritus Professor Yoshiaki Tainoshou of Kobe University regarding the geotechnical risks associated with the development of Yumeshima, the proposed site for Expo 2025.

6. Subsidence due to Consolidation of Alluvial and Diluvial Clay Layers

The professor articulates that clay, inherently soft and high in water content, tends to flatten and shrink due to the expulsion of interstitial water under the load of thick landfill layers, resulting in consolidation subsidence. Once subsided, these clay layers do not revert to their original state.

Consequently, only lightweight structures can be erected atop these layers. The City of Osaka (2017) anticipates a subsidence of over 10 cm, proposing elevated landfill as a countermeasure. However, as time progresses, further subsidence is anticipated to become a significant issue.

The Kansai International Airport has faced considerable challenges, not only with the alluvial clay layers but also with older diluvial clay layers that were not initially anticipated, resulting in subsidence exceeding predictions.

The City of Osaka’s “Osaka Port Landfill Project” (2014) acknowledges the issue of landfill layer consolidation subsidence. Still, the underlying alluvial and diluvial clay layers present a more substantial concern due to their extensive consolidation subsidence.

Located immediately below the landfill layers (see Figure 3), alluvial clay exhibits standard penetration test N-values between 2 to 5 (with values below 10 indicating softness), indicating a soft layer similar to paddy fields, prone to consolidation subsidence under the weight of the landfill.

Furthermore, with the alluvial clay layer being over 20 meters thick, there is a grave concern for subsidence beyond initial projections.

While the sand drain method has been considered to expedite consolidation subsidence (City of Osaka, 2017), Kansai International Airport experienced greater-than-expected subsidence despite this method.

Beneath the alluvial clay layer lies an older diluvial clay layer (Ma12) (see Figure 3), exceeding 10 meters in thickness with N-values of about 4 to 5, denoting softness. The lack of anticipation for the consolidation subsidence of this layer was contributory to the predicament.

For the Yumeshima Expo and IR project site, unmitigated consolidation subsidence could result in residual ground subsidence exceeding 50 cm (City of Osaka, 2014), far surpassing the allowable residual subsidence.

Moreover, as the landfill layer also undergoes consolidation subsidence, many areas are expected to exceed the 50 cm threshold, jeopardizing the maintenance of the planned ground level.

This consolidation subsidence could lead to a disconnect between buildings and ground, and coastal areas may see dikes subside, potentially failing to serve their intended purpose, arguably making it the most significant concern for the Expo and IR project development.

Additionally, landfill operations are slated to conclude a year before the Expo (City of Osaka 2017), potentially hindering adequate compaction of landfill materials.

Potential countermeasures such as sand compaction piles, piling, ground improvement (solidification, etc.), and deep mixing methods are under consideration, but no concrete plans have been presented.

Moreover, the assumption that consolidation subsidence occurs uniformly is not guaranteed, and long-term predictions over a decade are extremely challenging to ascertain through laboratory experiments due to parameter limitations.

In essence, the extent of actual subsidence remains uncertain until the landfill is completed, illustrating that the issue of consolidation subsidence remains unresolved to this day.

Dios is a real estate company that supports foreign government diplomats and foreign company executives coming to Japan. Headquartered in Nakanoshima, central Osaka, Dios is the only real estate company in Osaka that specializes in serving foreign clients.

For 25 years in Osaka, Dios has specialized exclusively for foreign expats who do not speak Japanese. Therefore, we have a wealth of experience and knowledge regarding the problems that foreign customers may have and what services are necessary in Osaka Japan.

Usually, our main job is to purchase and install furniture and home electric appliances for foreign expats’ residences.
In that case the furniture lease period is generally 3 to 4 years.

The Expo will be for a maximum of one year, including the preparation period, and I believe there will be furniture and home appliances required for the pavilions as well as residences. The Expo will be the first time for Dios, but we will do our best to make the best possible proposals for our foreign customers.

Dios has experienced professional interior coordinator.
We pride ourselves on creating beautiful interiors for customers.
