Japan’s first cherry blossom forecast for 2026 revealed — here’s when Tokyo, Kyoto and Osaka will turn pink sooner than expected

Japan’s first sakura forecast for 2026 is here—revealing when Tokyo, Kyoto and Osaka are expected to turn pink and how early travellers should start planning their spring trip.

It may still be winter in Japan, but for travellers already dreaming of spring, there’s finally something concrete to plan around. Japan’s Meteorological Corporation (JMC) has released its first official cherry blossom forecast for 2026, offering an early glimpse into when the country’s iconic sakura season will unfold next year.

According to the forecast, Tokyo and Nagoya are set to see the first cherry blossoms on March 19, kicking off the season in central Japan. For those planning their trips around peak bloom rather than first sightings, patience will pay off — Tokyo is expected to reach full bloom around March 26, followed closely by Nagoya on March 28.

The forecast, released on December 18, covers flowering (kaika) and full bloom (mankai) dates for the popular Somei Yoshino cherry trees at nearly 1,000 locations across Japan, from Hokkaido in the north to Kagoshima in the south. JMC notes that this year’s outlook has been issued slightly earlier than usual, helped by the use of artificial intelligence and long-range temperature data from the previous autumn.

Key cherry blossom dates to bookmark for 2026

After Tokyo and Nagoya, cherry blossom season is expected to unfold quickly across other major cities.

Fukuoka and Kochi are likely to see their first blooms on March 20, with full bloom forecast around March 27 in Kochi and March 29 in Fukuoka.

Meanwhile, Osaka and Kyoto are expected to welcome sakura by March 24, with peak bloom anticipated around March 31.

JMC says Tokyo’s 2026 bloom is likely to arrive a few days earlier than last season, a trend that travellers and researchers have been watching closely in recent years.

Sakura season moves north in April

As usual, cherry blossom season will gradually travel northward as temperatures rise:

Sendai: In Japan’s Tohoku region, Miyagi Prefecture’s capital is expected to see cherry blossoms open around April 5, with full bloom arriving by April 10.

Aomori: Best known for its Nebuta Festival, Aomori is forecast to begin flowering on April 19, reaching peak bloom around April 22.

Sapporo: Farther north in Hokkaido, Sapporo’s sakura season arrives later, with first blooms expected on April 28 and full bloom around May 1.

Hokkaido remains the last major region to welcome sakura each year, making it a popular option for travellers who miss the blossoms in Tokyo or Kyoto.

JMC has clarified that this is only the first forecast, and dates may shift slightly as winter progresses. The next official update is scheduled for January 8, with further refinements expected closer to spring.

How Japan forecasts cherry blossom dates

Cherry blossom forecasting is more science than sentiment. According to JMC, flowering depends heavily on temperature patterns from the previous autumn and winter.

Cherry buds form during the summer of the previous year and then enter a dormancy phase, which allows them to survive winter. During this time, buds require sustained cold temperatures — typically between -5°C and 15°C — to properly “reset.” Once dormancy is broken, rising spring temperatures trigger the growth phase, leading to flowering.

Simply put, warmer springs accelerate blooming, while colder conditions delay it. That’s why JMC continues to update its predictions as winter unfolds.

For travellers planning a sakura trip in 2026, this early calendar offers a valuable head start — but flexibility remains key. Japan’s cherry blossom season may be fleeting, but with careful timing, it remains one of the world’s most rewarding travel experiences.
