徳島県 · Calendar 2026

January is a blank month on Tokushima's calendar — nothing on the site is dated here. The inland highlands are out of season, so plans collapse to the city and the coast. Fine for quiet, cheap travel; wrong month if you came for festivals.

February is empty on the calendar too. Late winter keeps the inland mountains off the table, leaving city and coastal plans only. It books easily and stays uncrowded — but if festivals or mountain scenery are the point, hold Tokushima for spring.

March starts cherry-blossom season, and Tokushima Castle Ruins is the only seasonal entry this month — with bloom weighted to the late half. Come early and you may find bare branches; slot Tokushima late in the trip if you can.

• 德島城跡

April holds two threads, but they barely overlap: cherry blossom at Tokushima Castle Ruins fades in the first half, while the Mt. Tsurugi climbing season only opens near month's end. Pick a half, and pack layers — the mountain stays colder than town.

Mt. Tsurugi is the only thread on the site in May, but conditions are as good as they get: before the rainy season, before the heat. No major city events, so this is a month for the mountain and unhurried travel.

June brings the rainy season, so Tokushima needs a plan B. The beach season at Ozato in Kaiyo opens and Mt. Tsurugi is still climbable, but both live or die by weather. Build two tracks: mountain and coast on clear days, city indoors otherwise.

July is when Tokushima's summer actually starts: fireworks at Retra! Suito Matsuri in Aibahama Park, beach season at Ozato, and Mt. Tsurugi still open. The trade-off is fierce heat and typhoons — work the early and late hours, and confirm events before you travel.

August is the busiest month and the one worth planning a trip around: Awa Odori turns central Tokushima into a venue, and beds vanish so completely that pop-up festival lodging appears. Book far ahead. Naruto's summer festival fireworks land earlier in the month.

September returns Tokushima to normal: the beach season at Ozato winds down, Mt. Tsurugi stays open, and crowds and rates fall well below August. But typhoon season peaks now — bridges and mountain roads can close, so avoid unchangeable flights.

October has no major events and Mt. Tsurugi as its only thread — which is also when the mountain is at its best: heat gone, typhoon season fading, autumn colour arriving high up. A quiet stretch, with none of August's lodging scramble.

• 劍山

November closes the Mt. Tsurugi climbing season: the window runs only to about mid-month, so put the mountain in the first half. Autumn colour has largely dropped to the lower slopes, and it is cold up top. The city is quiet and easy to book.

December is blank on the calendar, and the mountains have dropped out of season. What is left is the city, plus a coast that is now for walking rather than swimming — with the easiest booking and transport of the year.
