The best time to visit Japan, month by month

Japan has four clear seasons, and each changes what a trip feels like more than it changes what you can do. The weather notes below use Tokyo as the reference point, because that is where most trips start; Hokkaido is colder, Okinawa is warmer, and Kyoto and Osaka track Tokyo closely. The crowd notes are based on holiday calendars and on what we have seen at stations and temples across several years of trips.

The short version: spring and autumn are the best seasons for most first trips, and the second half of May and the first half of November are the sweet spots. The months to plan around are the three big domestic holidays, when the whole country travels at once.

Spring is the season everyone pictures, and it earns the reputation. In Tokyo, Kyoto and Osaka the cherry trees usually reach full bloom between late March and early April, and the whole country turns out to picnic under them. Full bloom lasts about a week, and a warm or cold March can move it by a week either way, so if the blossom is the point of your trip, build in a few flexible days and watch the forecasts from early March. Our cherry blossom guide tracks the season from Okinawa to Hokkaido.

The price is crowds and hotel rates. Late March and early April are among the most expensive weeks of the year for rooms in Tokyo and Kyoto, so book early; our guides to where to stay in Tokyo and where to stay in Osaka cover the areas that fill last. If you cannot get dates in the peak week, go north: the blossom reaches Tohoku in mid to late April and Sapporo around late April or early May. After Golden Week, May is our favorite month of the year: warm, green and calm. Pack layers either way; what to pack for Japan in spring has the list.

Summer starts wet. The rainy season, tsuyu, usually covers most of Honshu from early June to mid or late July, and Okinawa from May to June. It rarely rains all day, and temples and gardens look their best in it, but it is humid and grey. Hokkaido largely escapes it, which makes June a good month to go north.

Once the rain ends, it is hot. Tokyo and Osaka reach the low 30s °C most days in late July and August, with high humidity and warm nights. In return you get the festival season: the Gion Matsuri runs through July in Kyoto, fireworks displays fill summer weekends, and the climbing season on Mount Fuji runs from early July to early September (see climbing Mount Fuji). Plan sightseeing for early morning and evening, and spend the middle of the day on trains or indoors. The north is the easy answer: our Tohoku by local train route is at its best in summer.

September is still summer in all but name. It is hot for the first half, and it is the peak of the typhoon season, so it is the one month we would not pick for a tight first trip. By October the air turns dry and clear and stays that way into November, which makes this the best hiking season and the most reliable for weather.

Autumn color moves the opposite way to the blossom, from north to south and from the mountains down. It starts in Hokkaido's highlands in late September, reaches Tohoku and Nikkō in October and arrives in Tokyo and Kyoto in late November, often lasting into the first days of December. Kyoto in the last two weeks of November is as crowded as it is in cherry blossom season; Kyoto without the queues has the quieter alternatives.

Winter is the most underrated season. Tokyo, Kyoto and Osaka are cold but dry, with long runs of clear days and highs around 10°C, and this is when you are most likely to see Mount Fuji from the city or from the shinkansen. Outside the New Year break and Lunar New Year, January and February are among the cheapest months for hotels.

The north is a different country in winter. Hokkaido and the Japan Alps get some of the heaviest, driest snow anywhere, the ski season runs from December to March, and the Sapporo Snow Festival fills the city in early February. Onsen towns are at their best under snow. The one catch is the New Year holiday, from about 29 December to 3 January, when many businesses close and trains and shrines are packed.

Golden Week is a run of public holidays from 29 April to 5 May, with the biggest cluster from 3 to 5 May. Much of Japan takes the week off at once: shinkansen and flights sell out, hotel prices jump, and popular sights in Kyoto, Nikkō and Kamakura are packed. If your dates overlap, stay in one or two big cities, book all long-distance trains in advance, and save day trips for either side of the holiday. Tokyo itself is often calmer than usual, because so many residents leave.

Obon, in mid-August, is the summer equivalent. The main travel days usually fall around 13 to 16 August, when people return to their home towns; trains and expressways out of the big cities are at their busiest of the year. Temples and festivals are at their most interesting then, but book everything early. The same applies, on a smaller scale, to Silver Week, the September holiday cluster that forms in some years.

The rainy season is an inconvenience rather than a reason to cancel. Expect grey skies and frequent showers from early June to mid or late July on Honshu, carry a folding umbrella, and plan indoor backups for each day. Gardens and moss temples are at their best, and there are fewer visitors.

Typhoons are more disruptive but less frequent. The season runs roughly from July to October, with most storms near Japan in August and September. When one approaches, trains, ferries and flights are suspended for a day or so, then run again once it passes. Check the Japan Meteorological Agency forecasts in the days before you travel, keep a flexible day in the plan, and take out travel insurance that covers weather delays.

The advice above is for Honshu, the main island, where most trips happen. Two regions run on a different clock. Okinawa is subtropical: it is warm enough to swim from about April to October, its rainy season comes earlier, in May and June, and it is the part of Japan most often in the path of typhoons in late summer. Its cherry trees bloom in January and February, and winter there is mild enough for walking and diving.

Hokkaido is the opposite. It has no real rainy season, summers are warm and fairly dry, and July and August are its best months for hiking, flowers and escaping the heat further south. Autumn color starts there in late September, and from December to March it is a snow destination. The Japan Alps and the mountains of Tohoku sit in between: cool in summer, with color in October and deep snow in winter, and a hiking season that runs roughly from July to October once the snow clears from the higher trails.

If you have a choice, avoid three periods: Golden Week (29 April to 5 May), the Obon week in mid-August, and the New Year break from about 29 December to 3 January. In each of them domestic travel peaks, prices rise and some businesses close. The peak week of cherry blossom and late November in Kyoto are busy too, but those crowds come with a reason to be there.

Beyond the calendar, avoid a packed schedule in August, when the heat makes long sightseeing days hard work, and avoid a tight itinerary in September, when a typhoon can cost you a day. For a first trip in spring or autumn, our 10-day first-timer's loop is built around the best of both seasons.
