Japan in the Rainy Season: Where to Go in June and How to Handle the Rain

If June is the only month you can get leave, the phrase rainy season in Japan may give you pause. In practice, tsuyu means humid weather with frequent rain, some long wet days, and plenty of grey but dry stretches in between. It is not a month of constant downpour. An upside people often overlook is that many famous places are quieter than in cherry blossom or autumn colour season, trees and moss look vividly green, and it is the season of hydrangeas. It suits travellers who can accept some rain and prefer a calm mood over postcard skies. This guide helps you decide where to go, which kind of town to choose, and how to plan so the weather does not wreck the trip.

The rainy season at a glance

Roughly speaking, Okinawa tends to enter its rainy season first, around late May into June, while the main island from Kyushu up to the Kanto area usually enters tsuyu around early June and leaves it in mid to late July. Hokkaido has no distinct rainy season, although it still gets rainy days. The start and end dates announced by the meteorological authorities change every year, so treat all of this as a guide only. What to expect is humid air, easy sweating, clothes that dry slowly, and, toward the end of the season, spells of very heavy rain in some areas that can disrupt travel.

Region by region

Popular highlights that work in the rain

The headline attraction of June is the hydrangea, or ajisai. In Kamakura several temples are known for hydrangeas, such as Meigetsu-in and Hase-dera, both reached on the Enoshima Electric Railway. Hakone has the Hakone Tozan Railway, which runs past flowering roadside hydrangeas while they are in bloom. Kyoto has suburban temples such as Mimuro-to-ji in Uji, famed for its hydrangeas. Wet flowers and trees often look better than under harsh sun, but the real flowering window depends on that year's weather.

For heavy-rain days, always keep an indoor list in your pocket. Good candidates include the following.

• Museums and indoor attractions, such as teamLab Planets in Toyosu, Tokyo, and the Kaiyukan aquarium in Osaka.
• Covered shopping streets such as Shinsaibashi-suji in Osaka and Teramachi in Kyoto, plus the underground malls around Umeda and Tokyo Station.
• Hot springs and ryokan stays, for example around Hakone, which suit days when you do not want to walk in the rain.
• Temples with moss gardens, such as Gio-ji in Arashiyama, where the moss looks its greenest after rain.

Smaller cities worth a June visit

Mid-sized cities often feel good to walk in the rain, because old quarters and shops sit close together. Kanazawa has Kenroku-en garden and its tea and samurai districts, which look lush after rain, with museums to duck into. Takayama offers its old town and morning markets, while Matsumoto has its black castle, which photographs well under cloud. If you want the most comfortable weather, Hokkaido cities such as Sapporo, Otaru and Hakodate suit anyone who dislikes humidity most. Lavender in Furano generally blooms a little later, so do not expect full purple fields in June.

Booking and getting around in the wet

Because there are fewer visitors than in peak seasons, finding rooms and tickets is often less stressful, but choose accommodation with flexible change or cancellation terms where that fits. Shinkansen and main-line trains normally keep running in the rain, although heavy rain or strong wind can cause delays or temporary suspensions on some lines. Leave slack on the day you fly home and avoid putting something important on a final day with no spare time. Umbrellas are sold at convenience stores, but a thin rain jacket and quick-drying shoes are more comfortable.

1. 1Check the forecast one to two days aheadSwap outdoor and indoor days according to the outlook instead of locking every day in before you leave.
2. 2Pack for wet weatherA thin rain jacket, waterproof pouches for phone and bag, spare socks, and something to help shoes dry quickly.
3. 3Keep spare time for the most weather-dependent plansWide views, mountain walks or boat trips should have a spare day in the plan.

On days when plans change suddenly, having data helps: checking the rain radar, seeing which train line is delayed, and finding a nearby cafe or museum. A Japan eSIM set up before departure suits a rainy season trip.

Sample June routes

The first route suits anyone who wants to limit rain risk: Sapporo, Otaru and Hakodate in Hokkaido for about five to seven days, with cool air and no dominant rain. The second is for people who accept some rain: two to three days in Tokyo, half a day in Kamakura for hydrangeas, a hot-spring night in Hakone, then Kyoto and Osaka, swapping outdoor days and museum days by forecast. The third is Kanazawa, Takayama and Matsumoto, good for travellers who have done the big cities and want a quieter mood.
