Ask any travel guide about visiting Japan in June and you’ll get the same warning: “It’s rainy season — avoid it.” As someone who lives here, let me tell you a secret: tsuyu (梅雨) is one of the most underrated times to visit Japan.

What Exactly Is Tsuyu?

Tsuyu, literally “plum rain,” is Japan’s rainy season. It typically runs from early June to mid-July, moving north from Okinawa (which starts in May) to Tohoku. Hokkaido barely gets a rainy season at all.

Here’s what guidebooks don’t emphasize: it doesn’t rain all day, every day. A typical tsuyu week has 2-3 rainy days, often as light drizzle, mixed with cloudy and even sunny days. It’s nothing like a tropical monsoon.

Why June Is Secretly Great

1. The Crowds Disappear

The difference between Golden Week (early May) and mid-June at popular spots like Fushimi Inari or Arashiyama is staggering. Temples that require shuffling through crowds in spring feel almost private in June.

2. Hydrangeas (Ajisai) Are Spectacular

Japan does hydrangea season the way it does cherry blossoms — with full devotion. Famous spots include:

  • Meigetsu-in, Kamakura — nicknamed “the Hydrangea Temple,” famous for its blue blooms
  • Hakusan Shrine, Tokyo — hosts an annual hydrangea festival in mid-June
  • Mimuroto-ji, Kyoto — 20,000 hydrangea plants across a hillside garden

And here’s the thing: hydrangeas actually look better in the rain.

3. Prices Hit Their Annual Low

June sits in the dead zone between Golden Week and summer holidays. Flights and hotels are consistently at their cheapest of the year, sometimes 30-40% below peak season rates.

4. Rainy Days Are What Japan Was Built For

Few countries handle rain as gracefully as Japan:

  • Department store food halls (depachika) — entire basement floors of culinary wonder
  • Onsen — soaking in a hot spring while rain falls outside is peak Japan
  • Museums and aquariums — world-class and rarely crowded in June
  • Covered shopping arcades (shotengai) — entire streets with roofs, found in every city

What to Pack

  1. A compact umbrella — or buy a clear plastic one at any convenience store for about 500 yen (a cultural experience in itself)
  2. Quick-dry shoes — leather shoes and canvas sneakers suffer; sandals or waterproof sneakers win
  3. A light rain jacket — June is warm (20-28°C), so heavy raingear gets sweaty fast
  4. Anti-humidity hair products — trust me on this one

What to Watch Out For

To be fair, tsuyu has real downsides:

  • Humidity — it’s sticky. Hotels and trains are well air-conditioned, but walking outside can feel like a sauna by late June
  • Mt. Fuji climbing is closed — the official season starts in July
  • Laundry dries slowly — use hotel dryers or coin laundries with gas dryers
  • Occasional heavy rain days — have an indoor backup plan for each day of your itinerary

A Perfect Rainy Day in Tokyo (Sample Itinerary)

  • Morning: teamLab Planets (indoor, surreal, and partially barefoot — rain irrelevant)
  • Lunch: Ramen in a covered arcade in Nakano or Asakusa
  • Afternoon: Department store basement food hall crawl in Ginza, then a craft coffee shop
  • Evening: Izakaya dinner under the train tracks at Yurakucho — the rain on the awnings adds atmosphere

The Bottom Line

If your dream Japan trip is all about outdoor hiking and Mt. Fuji, June isn’t your month. But if you want temples without crowds, hydrangeas in full bloom, the year’s best hotel prices, and an excuse to spend hours in onsen and food halls — tsuyu might be exactly when you should book.

The rain is part of the experience. Bring an umbrella and lean into it.
