I’ve been following using this source rather than the maps, particularly over the past week or so.
Current bud growth rate for

Tokyo: 60%, flowering date 21st Mar & full bloom 28th Mar

Kyoto: 59%, flowering date 22nd Mar & full bloom 31st Mar

Last year I found this same source to be the most accurate. Even so, the Sakura came to full bloom and then withered earlier than was predicted at quite a few of the micro locations listed.
There are some long, long spells of very warm weather coming up, both in Tokyo and Kyoto. I’m personally expecting the forecast trend to edge towards earlier dates (further North than Sendai is a different story)
