Tokyo in May is the best-weather month of the year with one enormous caveat at the front of it. Golden Week runs from 29 April to 5 May 2027 and puts the entire country on the move; after it ends, May delivers 23°C days, low humidity, the year’s second sumo tournament and two of Tokyo’s largest festivals, before the rainy season arrives in June.
Golden Week 2027: the dates, and why they matter
Golden Week is a cluster of Japanese public holidays at the turn of April and May, and 2027 produces a long one:
- Thursday 29 April – Showa Day
- Monday 3 May – Constitution Memorial Day
- Tuesday 4 May – Greenery Day
- Wednesday 5 May – Children’s Day
Take Friday 30 April off and that is seven consecutive days, 29 April to 5 May. Millions of people do exactly that. The practical consequences for a visitor are severe and entirely predictable: shinkansen reserved seats sell out weeks ahead, domestic flights double, hotel rates across Japan spike, and every headline destination – Kyoto, Hakone, Nikko, Kamakura, Mount Fuji’s Five Lakes – is at its worst of the year.
Tokyo itself is the exception that partly rescues this. Because so many Tokyoites leave, the city can feel calmer than usual on the middle days, even while the day-trip destinations around it are overwhelmed. If your dates land inside Golden Week, stay in the city and do Tokyo things. If they do not, arrive from about 7 May and you get the same weather at ordinary prices.
Weather: the best month of the year
May averages a high near 23.5°C and a low near 15°C, with about 140 mm of rain over eleven days. That rain total sounds high and behaves gently – it arrives as passing showers rather than the continuous grey of the June rainy season, and humidity is still low. Days are long, evenings are warm enough to sit outside, and the air has not yet turned heavy.
This is the month to walk. Tokyo rewards it more than almost any city, and May is the only stretch of the year when you can do it from morning to night without either a coat or a change of shirt.
Sanja Matsuri: Tokyo’s biggest street festival
Sanja Matsuri at Asakusa Shrine is the largest and rowdiest of Tokyo’s three great Shinto festivals: three days, around a hundred portable shrines (mikoshi) carried at a run through the streets of Asakusa by teams of bearers, and crowds usually reported between one and two million across the weekend.
It is held on the third weekend of May – which in 2027 falls on 14–16 May – but the shrine confirms the dates each spring, so check before booking around it. Go on the Sunday morning for the main mikoshi processions, accept that you will be in a crowd, and be aware that Asakusa’s stations are close to gridlocked for several hours either side.
In odd-numbered years, and 2027 is one, Kanda Matsuri also takes place in mid-May – a rival for the title of Tokyo’s biggest festival, centred on Kanda Myojin and processing through Nihonbashi and Marunouchi. Two of Tokyo’s three great festivals in the same month is a 2027-specific reason to come in May.
The May sumo tournament: 9–23 May 2027
The Natsu Basho runs 9 to 23 May 2027 at the Ryogoku Kokugikan – fifteen days, Sunday to Sunday, as every grand tournament is. It is the second of the three Tokyo tournaments in the year.
Advance tickets go on sale roughly a month ahead; the opening and closing weekends go first. A limited number of same-day standing-room tickets are sold at the venue each morning, which means an early queue. The top-division bouts run from about 16:00, so a weekday afternoon arrival is the low-effort way to see the part everyone comes for.
What is in flower, and where
The cherry blossom is long gone by May – that is a late-March and early-April event. What May has instead:
- Wisteria, at the very start of the month in Tokyo, at Kameido Tenjin above all.
- Azaleas, through late April and early May; Nezu Shrine in Bunkyo runs a festival among thousands of them on a hillside behind the shrine.
- Roses, mid-May, at the Kyu-Furukawa Gardens and the Jindai Botanical Gardens, both of which stage rose festivals.
- Irises, from late May into June, at Meiji Jingu’s inner garden and at Horikiri Shobuen.
None of these draws anything like the cherry-blossom crowd, which is most of their appeal.
Day trips: the best month for them
Outside Golden Week, May is the correct month for everything around Tokyo. Hakone without the winter cold or the summer haze; Nikko with the mountain roads fully open; Kamakura before the humidity; the Fuji Five Lakes with the mountain still carrying snow.
One caution: Mount Fuji is not climbable in May. The official season opens on 1 July and the trails, huts and mountain services are closed before then. In May you photograph it from the lakes. Day trips from Tokyo has the travel times and the practical routes.
Prices: two different months
Golden Week is among the two or three most expensive travel weeks of the Japanese year, alongside New Year and the August Obon period. From about 7 May, rates fall back to ordinary shoulder-season levels and stay there until the summer holidays begin in late July.
That mid-May to mid-June window – good weather, normal prices, no holiday crowd – is arguably the best value in the Tokyo calendar. The Tokyo travel budget sets out the daily numbers.
What to wear
Light layers. Days in the low twenties, evenings that drop to fifteen, and strong sun – May’s UV is higher than most visitors expect. A light jacket for the evening, comfortable shoes for long days, and something with sleeves for temples. You will not need rain gear every day, but a folding umbrella earns its space; convenience stores sell them for a few hundred yen if you get caught.

Frequently asked
Is May a good time to visit Tokyo?
It is the best-weather month of the year – around 23°C, low humidity, long days – provided you avoid Golden Week at the start. From about 7 May you get the same weather at ordinary prices, plus the May sumo tournament and Tokyo’s biggest street festivals.
When is Golden Week in 2027?
The holidays fall on Thursday 29 April, Monday 3 May, Tuesday 4 May and Wednesday 5 May. With Friday 30 April taken off, that makes seven consecutive days from 29 April to 5 May, and most of Japan travels during it.
Should I avoid Tokyo during Golden Week?
Tokyo itself is more bearable than the places around it, because so many residents leave the city.
