愛媛県 · Calendar 2026

January is a blank month on Ehime's calendar — nothing seasonal is listed here. It's low season, so crowds and lodging pressure are minimal; treat Ehime as a slow city-and-food stop rather than a date-driven trip.

February is also empty on this calendar — Ehime's quietest stretch. Facing the Inland Sea it stays dry and fairly mild in winter, and booking pressure is at its lowest, so it suits a low-key city stay over a highlight-driven trip.

The only March listing here is Ozu Castle, and its window sits in cherry-blossom season. Bloom timing shifts year to year, so schedule it as a swappable half-day rather than building the whole trip around it.

• 大洲城

April carries the same single listing, Ozu Castle, in the back half of its seasonal window. Blossoms are a gamble this late, but the weather is settled before the rainy season, so a castle-town walking day holds up either way.

• 大洲城

Nothing seasonal is listed for Ehime in May, which is not the same as a bad month: it falls before the rainy season and before the summer heat, so outdoor days are comfortable and you can pick dates purely on flight and lodging prices.

June opens the Hijikawa cormorant-fishing season, with Ozu's matching ukai meal available alongside it, so viewing and dinner can sit in the same day in Ozu. It also overlaps the rainy season, so confirm the day is running before you commit.

• 大洲鵜飼料理
• 肱川鵜飼

July is one of Ehime's fullest months: Mount Ishizuchi enters its summer climbing window while Hijikawa's cormorant fishing and the Ozu ukai meal are still running. Heat and typhoon season mean the mountain needs a backup plan and slack in the schedule.

• 大洲鵜飼料理
• 肱川鵜飼
• 石鎚山

August keeps both tracks open — Mount Ishizuchi's climbing season, Hijikawa cormorant fishing, and the Ozu ukai meal. The Obon holiday makes it one of Japan's busiest travel stretches, so book early, put the mountain day first, and keep river plans swappable.

• 肱川鵜飼
• 石鎚山

September is Ehime's densest overlap: Matsuyama's imotaki season starts mid-month just as Mount Ishizuchi's climbing window, Hijikawa cormorant fishing and the Ozu ukai meal wind down. Catching both sides means threading the middle weeks, and typhoon season is still live.

• 松山いも炊き
• 大洲鵜飼料理
• 肱川鵜飼
• 石鎚山

Matsuyama's imotaki is the one listed reason to be here in October, and the trade-off is clear: settled weather at the tail of typhoon season and low risk of disruption, but few seasonal draws — plan around the city and food rather than events.

• 松山いも炊き

Matsuyama's imotaki still runs in November but closes mid-month, so later dates risk missing it. Shikoku's mountain foliage arrives around now as well — cool, low-friction travel — though timing moves year to year, so don't pin the trip to one day.

• 松山いも炊き

December is blank on Ehime's calendar. Early winter means thinner crowds and easy booking, which suits a short city stay or a stopover while moving through Shikoku — but if you want a clear seasonal theme, this month won't supply one.
