The 20th Asian Games officially opened in Nagoya, Japan, on Saturday, 19 September 2026, with a colourful ceremony at Nagoya City Mizuho Park Athletic Stadium bringing together delegations from 45 nations and regions.

The ceremony marked the formal start of Asia's biggest multi-sport event after a difficult build-up in which organisers faced complaints about accommodation, transport and registration.

A celebratory opening after a difficult final week

Music, dance and fireworks provided the spectacle inside the stadium as the Games moved from preparation into competition. According to Reuters , the opening followed several days of operational problems reported by athletes and officials arriving in Aichi and Nagoya.

The official Aichi-Nagoya 2026 programme confirms that the opening ceremony was staged at Nagoya City Mizuho Park Athletic Stadium and that the Games run from 19 September to 4 October.

Accommodation became the biggest logistical issue

Unlike many previous editions, Aichi-Nagoya 2026 does not use a single traditional athletes' village. Instead, competitors and team officials have been spread across hotels, temporary wooden modular accommodation and a cruise ship.

Reuters reported earlier in the week that roughly 17,000 athletes and officials were expected, above the original planning figure, increasing pressure on accommodation and transport arrangements. Organisers said space had been secured for all participants and established support centres to address complaints.

The cruise ship Costa Serena was brought in as part of the accommodation plan, while temporary units and hotels were used across the host region. Some delegations raised concerns about room size, transport delays and the time required to move between accommodation and competition venues.

Transport and registration also drew complaints

The build-up was not limited to housing concerns. Athletes and officials also reported delays involving buses, accreditation and registration. Organisers and the Olympic Council of Asia said the issues were being worked through as teams settled into the Games.

The unusual accommodation model is partly linked to the decision not to build a dedicated athletes' village, a move intended to reduce construction costs and make greater use of existing infrastructure.

A huge sporting programme now takes centre stage

Once the ceremony ended, attention shifted firmly to competition. The 2026 Asian Games programme features 43 sports and hundreds of medal events, with events spread across Aichi, Nagoya and other Japanese locations.

The Games include established disciplines such as athletics, swimming, basketball and football alongside newer additions including mixed martial arts, padel, surfing, virtual taekwondo and teqball. Several events also contribute to qualification pathways for the Los Angeles 2028 Olympic Games.

What happens next

Competition had already begun in several sports before the formal opening, but the first full day after the ceremony will put the focus on medals rather than logistics. Organisers will nevertheless remain under scrutiny over transport and accommodation as thousands of participants move between venues during the two-week programme.

The opening ceremony offered Aichi-Nagoya 2026 a chance to reset the mood after a troubled final build-up. The success of the Games will now depend not only on the competition itself, but also on whether organisers can keep the large and geographically dispersed event running smoothly through 4 October.
