A recent economic report has cast a shadow over the celebrated success of the 2025 Osaka-Kansai Expo, revealing that its massive economic benefits were largely confined to Osaka, leaving surrounding prefectures in the Kansai region grappling with unexpected downturns. While the Expo generated an estimated 3 trillion yen, the post-event analysis points to a significant “straw effect,” where Osaka’s boom came at the expense of its neighbors.
The Promise vs. The Reality of Regional Prosperity
The Osaka-Kansai Expo was promoted not just as an event for Osaka, but as a catalyst for the entire Kansai region. The expectation was that international and domestic visitors would use the Expo as a gateway to explore the rich cultural tapestry of nearby areas like Kobe, Kyoto, and Nara. The goal was to create a widespread economic ripple effect that would boost tourism and local economies across the region.
However, a report by the Yomiuri Shimbun on May 26, 2026, paints a different picture. The analysis suggests that instead of dispersing, tourist traffic and spending became hyper-concentrated in Osaka, creating a ‘winner-takes-all’ scenario.
A Data-Driven Divide: Osaka’s Gain, Kansai’s Pain
The numbers highlight a stark contrast between Osaka and its neighbors during the Expo period.
Osaka’s Unprecedented Boom
Data shows that key tourist attractions in Osaka City saw a significant surge in visitors. For instance, Osaka Castle experienced a 9.2% increase in attendance compared to the previous year, demonstrating the Expo’s direct positive impact on the city’s core tourism assets. Hotels, restaurants, and retail outlets within Osaka also reported record-breaking sales.
The Struggle in Surrounding Areas
In sharp contrast, many businesses in neighboring prefectures felt a pinch. The report highlighted several concerning statistics:
- Kobe’s Chinatown (Nankinmachi), a popular tourist destination in Hyogo Prefecture, reported a 20-30% decline in customers during the Expo. Local business owners speculated that tourists were either spending their entire itinerary within Osaka or were deterred by anticipated crowds and high accommodation prices throughout the region.
- Other major tourist spots, including destinations in Kobe, the famous Arima Onsen hot spring resort, and even parts of Kyoto, saw significant decreases in visitor numbers. This indicates that tourists who came for the Expo did not venture far beyond its host city.
The ‘Straw Effect’ and Future Implications
This phenomenon, where a single major attraction or city siphons off resources and visitors from its surrounding areas, is known as the ‘straw effect.’ The Expo, intended to be a fountain of prosperity for all of Kansai, inadvertently acted as a powerful straw, drawing leisure spending almost exclusively into Osaka.
Lessons for a Sustainable Future
This report serves as a critical wake-up call for regional tourism planning. For Kansai to achieve sustainable, long-term growth, it must address this imbalance. Future strategies will likely need to focus on:
- Integrated Transportation: Creating more seamless and affordable travel passes that encourage multi-prefecture journeys.
- Collaborative Promotion: Marketing Kansai as a single, diverse destination rather than a collection of competing cities. This involves creating curated itineraries that naturally guide visitors from Osaka to the port city of Kobe, the ancient capital of Kyoto, and the serene nature of Wakayama.
- Dispersal-Oriented Events: Designing future large-scale events with programs and venues physically spread across different prefectures to ensure shared benefits from the outset.
While the 2025 Expo was an undeniable economic success for Osaka, its legacy now includes an important lesson on the challenges of regional co-prosperity. For travelers planning a trip to Kansai, this serves as a reminder that the region’s true charm lies in its diversity—a diversity that extends far beyond the bright lights of Osaka.
