高知県 · Calendar 2026

January in Kochi is about produce rather than events: Umaji yuzu products are still in season and Tosa buntan citrus is coming in. Plan around markets and produce halls, and leave luggage room — buntan is heavy.

February is quiet: Tosa buntan is the only thing in season here. Treat Kochi as a slow stop — city, markets, coastal transit — rather than a festival destination, and check import rules before carrying fresh fruit home.

• 土佐文旦

March closes out the Tosa buntan season, and Kochi is among the first places in Japan to see cherry blossom, with city trees opening late in the month. The event calendar is thin, so build the days around food and scenery.

April has no dated entries here — a blank month. Blossom is mostly finished by now, but it lands in the mild, drier stretch before the rainy season, which suits a slow drive or rail loop. Festival-hunters should look elsewhere.

May opens the Niyodo River rafting season, and it lands before the rainy season, so outdoor plans hold up. Water trips usually need booking ahead rather than walk-up, and you'll get wet — pack a change of clothes.

June is rainy season in Kochi, and Niyodo River rafting is the only thing on the calendar. Expect cancellations and plan indoor fallbacks — the trade-off is thin crowds and easy lodging if your itinerary can flex.

• 仁淀川泛舟

The first half of July is often still the tail of the rainy season; once it lifts, heat and typhoon season arrive together. Niyodo River rafting is the obvious move — go early in the day, and keep a spare day for transport disruptions.

August is Kochi's busiest month: the Kochi City fireworks fall on the eve-festival night of Yosakoi, so book city lodging far ahead. Every seat is paid — there is no free viewing area — so budget and ticket early. Rafting fills the daytime.

September still sits in typhoon season and is one of the thinnest months here — Niyodo River rafting is the only thing running. Heat lingers but crowds are gone; book refundable transport and rooms, since water trips stop first.

October is one of the easiest months to schedule: Niyodo River rafting is in its final stretch, Umaji yuzu products come into season, and colour starts in the hills. Settling weather and less typhoon risk make outdoor days more reliable.

November puts Kochi into autumn-colour season, with Umaji yuzu products the thing worth buying. Pair valley and mountain scenery with a produce-hall stop — and note that river rafting has closed for the year, so don't plan around it.

December is a quiet month — Umaji yuzu products are the only thing still in season. It works better as a food-and-shopping stop or an overnight on a longer driving route than as an outdoor trip; check year-end closures before you go.
