Best Time to Visit Tokyo: Month-by-Month Weather, Sakura & Crowd Guide (2026)

Late March to early April and late October to early December are Tokyo's two best windows, and they are best for opposite reasons.

Spring buys you cherry blossom and mild days — Tokyo's April normal is 19.4°C high, 9.8°C low. It also buys you the heaviest crowds of the year and the highest hotel rates.

Late autumn is the quietly better deal. November averages a 16.7°C high with just 96.3 mm of rain and 64% humidity — the driest, clearest stretch of the year — and the ginkgo and maple peak runs from late November into early December.

The months to think hard about are July and August, which are genuinely punishing now, and September and October, which most guides wrongly sell as "dry autumn."

Every figure on this page comes from the Japan Meteorological Agency's 1991–2020 climate normals for Tokyo station 47662.

JMA 1991–2020 normals for Tokyo. High and low are °C, rain in mm, humidity as a percentage.

| Month | High | Low | Rain | Humidity |

|---|---|---|---|---|

| January | 9.8 | 1.2 | 59.7 | 51% |

| February | 10.9 | 2.1 | 56.5 | 52% |

| March | 14.2 | 5.0 | 116.0 | 57% |

| April | 19.4 | 9.8 | 133.7 | 62% |

| May | 23.6 | 14.6 | 139.7 | 68% |

| June | 26.1 | 18.5 | 167.8 | 75% |

| July | 29.9 | 22.4 | 156.2 | 76% |

| August | 31.3 | 23.5 | 154.7 | 74% |

| September | 27.5 | 20.3 | 224.9 | 75% |

| October | 22.0 | 14.8 | 234.8 | 71% |

| November | 16.7 | 8.8 | 96.3 | 64% |

| December | 12.0 | 3.8 | 57.9 | 56% |

The number that surprises everyone: October is Tokyo's wettest month, and September is second. Not June, not the rainy season. That rain is typhoon rain, and it arrives in heavy bursts rather than the steady drizzle of tsuyu. Most travel pages get this backwards.

One caveat if you cross-check elsewhere: Tokyo's thermometer moved from Otemachi to Kitanomaru Park in December 2014, and the new site runs about 0.9°C cooler in daily mean. JMA rebased the normals to the new site, so don't mix these figures with older 1981–2010 tables still floating around.

Tokyo's long-term normal is 24 March for first bloom (kaika) and 31 March for full bloom (mankai). Pages still quoting 26 March and 3 April are using the retired 1981–2010 normals.

2026 was an early year: first bloom 19 March, full bloom 28 March — five days ahead of normal. For context on how much this moves:

| Year | First bloom | Full bloom |

|---|---|---|

| 2023 | 14 March | 22 March |

| 2024 | 29 March | 4 April |

| 2025 | 24 March | 30 March |

| 2026 | 19 March | 28 March |

That is a 15-day spread in first-bloom dates across four years, which is exactly why booking flights around sakura a year ahead is a gamble.

How the date is decided: Tokyo's declaration hangs on specific Somei-Yoshino sample trees at Yasukuni Shrine. Kaika is called the first day five or six blossoms are open; mankai when about 80% of buds are. On 18 March 2026 two blossoms had opened and JMA held off; the next day it counted 61 and declared.

Forecasts are good but late. Japan Meteorological Corporation's first 2026 forecast, issued 18 December 2025, called 19 March for Tokyo and was exactly right. Weathernews moved between 18 and 22 March across five revisions. Expect accuracy within one to three days, but only from early March.

If you miss peak: Shinjuku Gyoen holds over 1,000 trees including early and late varieties, which stretches the usable window by a week either side of the Yasukuni date.

Kanto's tsuyu normally runs around 7 June to around 19 July. JMA always writes *around* — these are never sharp dates.

But here is the trap almost every English page falls into. JMA announces tsuyu twice. A preliminary call is made live during the season from forecasts; a confirmed value is issued in early September after reviewing what the weather actually did. In 2025 that revision moved the start 19 days earlier (10 June → 22 May) and the end 20 days earlier (18 July → 28 June), making 2025 the earliest tsuyu end since records began in 1951. Any page still saying "the 2025 rainy season ended 18 July" is quoting a dead number.

2026's preliminary dates are around 7 June to around 20 July, and the confirmed values were not out at the time of writing. Tokyo recorded 299.0 mm across that period against a 253.0 mm normal.

What tsuyu actually feels like: humidity in the mid-70s, grey skies, and rain that comes and goes rather than falling all day. Temples photograph beautifully in it, hydrangeas are at their peak, and hotel rates are noticeably softer. It is a genuinely underrated time to visit if you are not chasing blue sky.

August normals are a 31.3°C high with 23.5°C nights and 74% humidity, and July is barely gentler at 29.9°C. Those are the *normals* — recent summers have run hotter.

The part the numbers don't convey is the nights. A 23.5°C average low means the city never really cools, and walking days that would be pleasant in April become genuinely draining. If your itinerary is temples and neighbourhoods on foot, July and August will cut what you actually manage to see.

If you are locked into summer, the workarounds are real: start at first light and stop by 11:00, move the afternoon indoors or underground, and put the walking back in after 18:00 when the city is at its best anyway. Evening activities — a night bike ride, a neon photo walk — are not a consolation prize in Tokyo summer, they are the correct plan.

JMA's 1991–2020 normals: 25.1 typhoons form per year, 11.7 approach Japan, 3.0 make landfall. Formation peaks in August (5.7), but landfall peaks in September (1.0) — September storms are the likelier ones to actually hit.

Watch the definitions before you panic. JMA counts an *approach* as passing within 300 km of any Japanese observatory nationwide, which includes an Okinawa near-miss 1,500 km from Tokyo. *Landfall* excludes Okinawa entirely.

Two 2026 storms show the realistic range. Typhoon Jangmi (3 June) cancelled around 900 flights affecting some 90,000 passengers, halted shinkansen and metro services and triggered evacuation advisories — but most JR East lines were running again by 22:48 the same evening. Typhoon No. 15 (11–12 August) cancelled 64 flights and no shinkansen at all.

The honest framing: a typhoon usually costs you a 12 to 36 hour window, not a trip. Build one flexible day into a September or October itinerary and you will almost certainly be fine.

Tokyo's koyo runs later than most visitors expect — central Tokyo peaks late November to early December, weeks behind Kyoto and well behind the mountains.

JMA's Tokyo specimen trees sit in Kitanomaru Park. Recent observations: ginkgo yellowing on 3 December 2024 and 22 November 2025; maple reddening 3 December 2024 and 23 November 2025. Those describe one tree each, which is not the same as a garden looking its best, but they anchor the timing.

Where to go:

| Spot | Typical peak | Why |

|---|---|---|

| Meiji Jingu Gaien ginkgo avenue | late Nov – early Dec | 146 trees over 300 m, grown from 1908 Shinjuku Gyoen seed |

| Rikugien | late Nov – early Dec | Evening light-up, historically late Nov to early Dec |

| Showa Kinen Park | ginkgo mid-Nov, maples to mid-Dec | Katarai avenue 98 trees, Canale 106 trees |

| Mt Takao | mid-Nov – early Dec | Momiji festival, and an easy half-day from Shinjuku |

| Koishikawa Korakuen, Shinjuku Gyoen | late Nov – early Dec | Central, and reachable between other plans |

One correction worth knowing: the Jingu Gaien Ginkgo Festival has not run since 2019 — COVID, then the Gaien redevelopment. A light-up ran in late November 2025 instead. Don't plan around festival dates you find on older pages.

Three periods move domestic prices and fill trains. All dates below are from the Cabinet Office holiday register.

Golden Week. 2026 was split — a lone Wednesday on 29 April, then a five-day run from 2 to 6 May (6 May was a substitute holiday because Constitution Day fell on a Sunday). 2027 is worse: Shōwa Day falls Thursday 29 April, and anyone taking Friday 30 April off gets a seven-day run to 5 May. Expect that to be the peak congestion window of 2027.

Obon, 13–16 August. Not a public holiday, but customary leave, and one of Japan's three great travel crushes. A Tokyo quirk worth knowing: central Tokyo observes its own Bon on 15 July, while the August travel chaos hits Tokyo as residents *leave* for ancestral hometowns. In 2027 Obon falls Friday to Monday with Mountain Day on Wednesday 11 August — a heavy 11–16 August period.

New Year, 1–3 January. The one time attractions and shops close *despite* peak season. Meiji Shrine alone draws several million hatsumōde visitors across the three days.

And one to target: Silver Week, 19–23 September 2026. Respect for the Aged Day on Monday 21st and the Autumnal Equinox on Wednesday 23rd sandwich Tuesday the 22nd, which becomes a citizens' holiday automatically. It is the first true Silver Week since 2015 and the next is 2037. Domestic travel will be heavy — but if you want to see Japan on a genuine holiday, this is the rare one.
