Kumamoto, in the heart of Kyushu, is a prefecture of extraordinary landscapes and warm hospitality — the mighty reconstruction of Kumamoto Castle, the vast volcanic caldera of Mt. Aso, the misty riverside hot springs of Kurokawa Onsen, and a proud tradition of summer and autumn festivals. This guide gathers the events worth knowing for 2026, along with the timeless sights that make Kumamoto rewarding to visit year-round.
⚠️ Important — the 2026 Kumamoto earthquake: In late July 2026 Kumamoto was struck by an earthquake, and as a result many of the prefecture’s 2026 summer festivals were cancelled or greatly scaled back out of concern for safety and for those affected. Details below reflect what was known at the time of writing and will change. Please confirm the current status of any event on the official prefectural tourism site and the organiser’s website before you travel, and follow local guidance. Our thoughts are with everyone affected. Visiting Kumamoto respectfully — staying, eating and spending locally — is itself one of the most direct ways to support the region’s recovery.

Where Things Stand & How to Help
Even as festivals were affected, much of Kumamoto is open and welcoming visitors:
- Kumamoto Castle reopened in mid-August 2026 after a short closure for inspection. The castle sustained further damage in the earthquake, and its full, decades-long reconstruction (already underway since the 2016 quake, and targeted for completion around 2052) continues. Visiting — and the “Fukko Shiro” restoration-supporter scheme — directly aids the rebuilding.
- Aso, Kurokawa Onsen, Suizenji Garden and the coast remain among Japan’s finest destinations. Conditions can change; check access before setting out.
- Spending locally is support. As residents themselves have said, even a small visit helps. Choose local inns, restaurants and shops.
Fujisaki Hachimangu Autumn Grand Festival (藤崎八旛宮秋季例大祭) — September 2026
Kumamoto City’s largest and most famous festival, normally the herald of autumn. In 2026 the shrine’s sacred rites are scheduled across September 13–15 and 19–20, and the first-day ceremony, grand kagura and lion-dedication rituals are being conducted solemnly. However, owing to the earthquake, the festival’s celebrated Shinko procession — the Boshita parade with its richly decorated horses and zuihei attendants through the city streets — has been cancelled for 2026. In a normal year this vibrant horse-and-drum procession is the highlight; if you are reading ahead for a future year, it is one of Kyushu’s great autumn spectacles. Confirm the current year’s programme with Fujisaki Hachimangu .
Yamaga Toro (Lantern) Festival (山鹿灯籠まつり) — August 2026
One of Japan’s most beautiful festivals, in which women dance gracefully with golden paper lanterns balanced on their heads. For 2026 the festival was scaled down to the sacred rites at Omiya Shrine only; the Noryo fireworks and the famous Thousand-Lantern Dance (Sennin Toro Odori) were cancelled following the earthquake. In normal years (mid-August) the shimmering lantern dance and fireworks over Yamaga are unforgettable — worth planning around once the festival returns to full scale. Check Yamaga tourism for the latest.
Hi-no-Kuni Festival (火の国まつり) — August 2026
Kumamoto City’s big summer street festival, normally held in early August with the lively Otemoyan Sohodori mass dance through downtown. The 2026 edition (planned for late July–early August) was cancelled in the wake of the earthquake. In normal years it is the city’s summer centrepiece; check official channels for its return.
Aso Grassland Burning — Noyaki (阿蘇の野焼き) — late winter / early spring
Each year from roughly late February into March, the vast grasslands of the Aso caldera are deliberately burned in the centuries-old noyaki — a controlled burn that keeps the plateau’s rare grassland alive and prevents it reverting to forest. Seen from a distance, the lines of flame and the blackened, soon-to-green hills are extraordinary. Dates (in 2026 the main burns fell around late February and early March) shift with weather and cause road closures — always check Aso City / Aso tourism before visiting.
Cherry Blossom Season (Spring)
Kumamoto’s blossoms usually peak in late March to early April.
- Kumamoto Castle grounds — cherries against the great stone walls (check reconstruction access)
- Suizenji Jojuen Garden — an exquisite strolling garden modelling the old Tokaido road
- The Aso approaches and rural valleys
Autumn Leaves (Nov)
- Kikuchi Gorge — one of Kyushu’s loveliest maple valleys, superb in mid-to-late November
- Nabegataki Falls (Oguni) — the “waterfall you can walk behind,” framed in autumn colour
- Aso highlands and the caldera rim
Winter & New Year
- Hatsumode at Fujisaki Hachimangu and the prefecture’s shrines
- Kurokawa Onsen — its winter Yuakari bamboo-lantern illuminations along the river are magical
- Aso under crisp winter skies, ahead of the spring noyaki

Practical Tips
- Confirm everything before you travel. After the 2026 earthquake, event status, transport and site access can change quickly. Check the Kumamoto Prefecture tourism site , each organiser’s website, and local advisories.
- Travel respectfully. Some communities are still recovering; follow signage and staff guidance, and be mindful around affected areas.
- Your visit helps. Staying overnight, eating local specialities (Kumamoto’s basashi horse sashimi, taipien, Aso beef) and shopping locally directly supports recovery; consider the Kumamoto Castle restoration-supporter programme.
- Aso needs a car or planning. The caldera, Kurokawa Onsen and the gorges are spread out; a rental car or careful bus/train planning helps — and check for any road closures.
- Seasons are the safe bet. Kumamoto’s landscapes — Aso, Kurokawa, Kikuchi Gorge, Suizenji — reward a visit year-round regardless of the festival calendar.
