Tokyo Sets Record With 34 Straight Days of Rain

Rain fell in central Tokyo for a 34th consecutive day on September 29, 2026, marking the longest unbroken stretch of wet weather in the Japanese capital since records began in 1886, The Yomiuri Shimbun reported. The milestone sets a new benchmark for Tokyo, surpassing the previous record of 33 straight days of rain.

A New Record for the Capital

The 34-day run breaks the previous mark of 33 consecutive rainy days, which was set in 2019 between June 27 and July 29, according to the Japan Meteorological Agency. With weather records for the capital stretching back to 1886, the new streak stands out as an exceptional entry in Tokyo's meteorological history.

A Stalled Autumn Rain Front

The unbroken run of wet weather began on August 27 and has been driven by an autumn rain front that has stalled along the southern coast of Honshu, the country's main island.

Late-summer and early-autumn rainy spells are a regular feature of Japan's climate, but a stationary front of this duration settling over a major metropolitan area is rare, making the extended wet spell especially unusual.

The Record at a Glance

• 34 straight days: Rain fell in central Tokyo for a 34th consecutive day on September 29, 2026.
• Longest on record: The streak is the longest since records began in 1886.
• Start of the wet run: August 27.
• Cause: An autumn rain front stalled along the southern coast of Honshu, Japan's main island.
• Previous record: 33 days, set in 2019 between June 27 and July 29, per the Japan Meteorological Agency.

Why the Streak Matters

While seasonal fronts regularly bring rain to Japan in late summer and early autumn, the persistence of a stationary front for more than a month over a major metropolitan area is rare, underscoring how remarkable the capital's extended run of wet weather has been in the country's long climate record.
