Frequently asked questions regarding cherry blossom forecast
Q1: What is the 2025 schedule for the cherry blossom forecasts releases?
A1: Here are the scheduled releases:

Q2: What are the criteria for the flowering and full bloom dates?
A2: The criteria are the same as those used by Japan Meteorological Agency. The flowering period starts the first day when 5 to 6 or more flowers have started to bloom on the designated observation tree (i.e. sample trees), and the full bloom date is the first day when more than 80% of the buds have opened on the sample trees.
Q3: How many locations are expected?
A3: We announce forecasts for 84 locations nationwide. The forecast locations consist of 53 sample trees observed by each local meteorological observatory and 31 locations where observation data are obtained from cooperating agencies such as municipalities/local governments and parks.
Q4: What are the methods and characteristics of the Japan Weather Association’s cherry blossom forecast?
A 4: We use our proprietary forecasting model that focuses on the temperature trends from autumn onwards, which significantly influence the growth process of the cherry blossom buds. Our forecasts are based on accurate observation data from sample trees at local meteorological observatories and cooperating agencies, emphasizing meteorological principles. Japan Meteorological Association has been conducting cherry blossom forecasts since 2007, making this year the 19th year of our endeavour.
Q5: What data are utilised for forecasting cherry blossoms?
A5: The following data are used.
- Temperature observation data from the previous autumn to the forecast date
- Temperature forecast data from the forecast date to the blooming period (from Japan Weather Association’s point forecasts and long-term forecasts).
The temperature from the previous autumn to spring significantly influences the cherry blossoming period. Cherry buds form during the previous summer and then enter dormancy. Exposure to a certain period of low temperatures during winter breaks this dormancy, and the buds grow and bloom with rising temperatures. It is believed that higher temperatures promote faster bud growth and earlier blooming.
