Ajisai Season 2026: Where to See Japan's Hydrangeas Right Now (Late June)

The flower of the rainy season — peaking now

While the rest of the world dreads Japan's June tsuyu (rainy season), the hydrangea (ajisai) turns it into the prettiest few weeks of early summer. The blooms shift colour with the soil — deep blue, violet, pink — and look their absolute best wet, in late June, raindrops beading on the petals. This is a genuinely now phenomenon: most famous spots peak from mid-to-late June into early July, then fade.

Kamakura — the hydrangea temples

A day trip south of Tokyo, Kamakura is the spiritual home of ajisai:

• Meigetsuin, the 'Hydrangea Temple', is a single narrow approach lined with over 2,500 Hime-Ajisai bushes in one mesmerising shade locals call Meigetsuin Blue. Arrive before opening on a weekday — it is famously crowded.
• Hasedera spreads 40-plus varieties down a hillside overlooking the Pacific — one of Japan's most photographed early-summer scenes.

Hakone — the hydrangea train

From early June into early July, the Hakone Tozan Railway climbs through a tunnel of around 10,000 hydrangeas. Because the flowers bloom progressively higher up the mountain, Hakone's season lasts longer than the lowlands — a bonus if you're a little late. In 2026 a special evening 'Night Hydrangea Train' runs through late June past illuminated blooms; check current dates before you go.

Kyoto & Kansai

• Mimuroto-ji (Uji, near Kyoto) carpets a hillside with 10,000-plus hydrangeas and is one of Kansai's premier ajisai gardens — at its best in late June.

How to see them well

• Go on a weekday, early — the headline temples fill by mid-morning.
• Embrace the rain. Ajisai look richest wet; bring an umbrella, not disappointment.
• Carry cash for temple entry (often a few hundred yen) and check each temple's current bloom report, which many post online in June.

Bottom line

Ajisai is the rare Japanese 'bloom season' you can enjoy without months of planning — it's happening this week. Pick a Kamakura temple, the Hakone train, or Kyoto's Mimuroto-ji, go early, let it rain, and catch one of early summer's quietest, bluest pleasures before it's gone.
