Events are among the strongest reasons to fix a client's Japan dates — and in 2026 and 2027 the calendar is unusually rich, headlined by a continental multi-sport games and a world horticultural expo, wrapped around Japan's evergreen festival and music circuit. The catch is the same every time: the bigger the event, the earlier the city sells out. This calendar covers what is confirmed, when, and the lead times the trade should build in. For the traditional festival deep-dive, pair it with our Japan summer festivals guide.
The headline events
- Aichi–Nagoya Asian Games 2026 — Asia's largest multi-sport event runs 19 September to 4 October 2026, centred on Nagoya and across Aichi prefecture, with some events in the Greater Tokyo, Gifu, Osaka and Shizuoka areas. The opening ceremony is at Paloma Mizuho Stadium; 41 sports across the programme. The Asian Para Games follow on 18–24 October 2026. Expect Nagoya-region hotels to compress hard across these windows.
- GREEN×EXPO 2027 (International Horticultural Exposition), Yokohama — Japan's largest horticultural expo in 37 years, 19 March to 26 September 2027, on a roughly 100-hectare site in Yokohama. A six-month driver of demand into the Tokyo–Yokohama area with strong appeal for garden, culture and MICE clients — a natural companion to our Japan garden tours.
Music festivals 2026
Japan's big three draw international fans and pair well with a wider itinerary:
- Fuji Rock Festival — 24–26 July 2026, Naeba Ski Resort, Niigata. Japan's marquee outdoor festival in the mountains.
- Summer Sonic — 14–16 August 2026, split across Tokyo (ZOZO Marine Stadium and Makuhari Messe) and Osaka (Expo '70 Commemorative Park).
- Ultra Japan — 19–20 September 2026, Odaiba, Tokyo — the country's flagship EDM event.
The seasonal matsuri that recur every year
These traditional festivals run annually and anchor countless itineraries — book accommodation months ahead in the host cities:
- Gion Matsuri, Kyoto — all July, float processions on the 17th and 24th.
- Tenjin Matsuri, Osaka — 24–25 July, river boats and fireworks.
- Aomori Nebuta — early August, illuminated floats in Tohoku.
- Awa Odori, Tokushima — mid-August, Japan's great dance festival.
- Sapporo Snow Festival — early February, Hokkaido's ice-sculpture spectacle.
- Takayama Matsuri — spring and autumn, ornate festival floats in the Hida region.
Sumo fans should also note the six annual grand tournaments (honbasho): January, May and September in Tokyo, March in Osaka, July in Nagoya and November in Fukuoka — detail in our samurai and sumo experiences guide.
Lead times and how to sell around events
- Major sport and expo windows (Asian Games, GREEN×EXPO): book host-city hotels 9–12 months out, or base clients one city over and day-trip in — the dispersal play we build routinely.
- Music festivals: secure tickets and nearby lodging early; Naeba and Makuhari sell out first.
- Traditional matsuri: the host city fills months ahead on peak festival dates — reserved paid seating (where it exists) beats a hopeful spot on the kerb.
How a Japan DMC books around events
Events turn a soft enquiry into a fixed-date sale — but only if the beds, rail and access are actually secured. As your Japan DMC, we hold hotel allocation and shinkansen reservations across the event windows, arrange reserved viewing and tickets where available, and route clients to avoid the worst of the crowding — the same operational muscle behind our MICE and incentive programs. Timing also shapes the wider trip; see where to go in Japan by month.
FAQ
What are the biggest events in Japan in 2026? The Aichi–Nagoya Asian Games (19 September–4 October 2026) is the headline, followed by the Asian Para Games (18–24 October). On the music side, Fuji Rock (24–26 July), Summer Sonic (14–16 August) and Ultra Japan (19–20 September) lead the calendar.
When and where is GREEN×EXPO 2027? The International Horticultural Exposition, GREEN×EXPO 2027, runs 19 March to 26 September 2027 on a roughly 100-hectare site in Yokohama — Japan's largest horticultural expo in 37 years.
How far ahead should clients book around a major event? For the Asian Games and GREEN×EXPO, secure host-city hotels 9–12 months out, or base clients in a neighbouring city and day-trip in. Music-festival lodging near the venues sells out first and should be locked early.
Can you get tickets and reserved viewing for festivals? Where official tickets or reserved seating exist — as at some matsuri, sumo tournaments and the music festivals — we arrange them alongside the hotels, rail and transfers as one program.
