Discover why Osaka Bay is the smart choice for international conferences after Expo 2025. Mid-scale venues, English support, waterfront settings, and IR 2030 momentum.
Expo 2025 Osaka-Kansai concluded in October 2025 after welcoming 29 million visitors, dramatically revitalizing the region's MICE infrastructure with upgraded transport, hotels, and international partnerships that now benefit conference organizers.
The Osaka Convention & Tourism Bureau confirmed that events launched during the Expo continue into 2026, with international planners newly choosing Osaka over traditional destinations. Japan's MICE market is projected to grow to USD 2.0 billion by 2033. According to Osaka Convention & Tourism Bureau, Osaka Bay now positions itself as "Western Japan's largest event space."
Osaka Bay offers 40-50% lower conference costs than Tokyo equivalents, with greater scheduling flexibility, uncrowded waterfront settings, and direct metro access—ideal for mid-scale international events requiring 500-3,000 delegates.

A detailed cost analysis by Japan Meetings found that Osaka venues provide significant savings on venue rental, audiovisual equipment, and accommodation. Beyond costs, detailed hall specifications and capacity charts show that Osaka Bay offers specialized spaces that Tokyo's enclosed convention centers can't match.
Central Osaka venues excel for walk-in traffic but struggle with parking and crowded metro lines. Osaka Bay inverts this: 1,200 indoor parking spaces, less congested transit, and 20+ on-site restaurants that eliminate expensive catered lunch contracts.
ATC Hall provides 7,000㎡ across five versatile halls (10-3,600 capacity), 12 conference rooms, and museum-grade exhibition spaces—filling the gap between hotel ballrooms and mega-exhibition centers.

Offers museum-quality wooden flooring and variable LED lighting (1,140-2,710 lux), ideal for art exhibitions or luxury brand showcases.
Located 18 minutes from Honmachi Station, ATC Hall connects directly to Trade Center-mae Station through covered walkways. Grand Prince Hotel Osaka Bay sits within 3-minute walk, enabling morning keynotes at 9:00 AM with 8:50 AM hotel departures.
