Cherry blossoms appearing early in Nagano… about half a year early

Better early than never. It’s autumn once again in Japan, and that means sweet potatoes are in season, the leaves on trees turn a beautiful crimson, and cherry blossoms delight many with their gentle hues. You might have thought cherry blossoms were a spring thing, but nature likes to keep us on our toes every once in a while. On the morning of 17 October, visitors to Garyu Park in Suzaka City, Nagano Prefecture, were surprised to find a scattering of sakura among the autumn foliage. Garyu Park is famous as one of the best parks for cherry blossom viewing in Japan, but currently, the small flowers have been very patchy compared to what’s seen in the spring. Still, clusters of as many as 10 blossoms could be seen. ▼ “In Garyu Park, near the zoo, cherry blossoms are blooming out of season.

Sakura trees usually develop their buds throughout the summer, but just before the buds are ready to pop open, they’re held back by a hormone called abscisic acid. Abscisic acid is delivered to the buds by the leaves of the tree, and by the time the leaves naturally fall from the tree, the temperature is low enough to keep the buds in a state of dormancy by themselves. However, sometimes the leaves fall off prematurely due to other factors, the most common being the strong winds of typhoons that tend to make landfall in September and October. The combination of enough lost leaves and stubbornly high temperatures well into mid-October in many parts of Japan may strip away all of the natural checks that would prevent a sakura from blossoming, causing some to trigger prematurely. Luckily, Garyu Park boasts some 600 trees and should still have more than enough to put on its usual display next spring. It’s also expected to finally cool down in the following week, so if your part of Japan was recently hit by a typhoon, you might want to quickly check out cherry blossom trees near you and see if a little early sakura is waiting.
