It's super local for sure. I doubt this one even applies effectively to all of japan. I found out about this a long time ago and have used it as a loose structure for coming up with my own similar thing based on my own area and observations.

But at this level of granularity moving a couple hundred miles north/south or a thousand feet in elevation is enough to shift a lot of it around, both in timing and in most notable plant and animal life at the transitions.

It's really more of a years-long exercise in observation, record keeping, poetry, and sense of place. I doubt there's a pre-made one that works as is for anyone.
