Every one of these is a reason I would plan a whole trip: drift ice off Hokkaido, squid that light up Toyama Bay, snow monkeys in Nagano, Fuji turning red at dawn. Pick a month and the map shows what is happening then, with the peak weeks marked.
Nothing matches that combination. Try another month or type.
Plenty of people I hear from want more than a trip. Settle Japan covers visas and the move itself, and Maneki Homes finds houses for sale in the countryside around them.
Timing and locations come from the Earth Exhibit catalog, and dates shift a week or two with each year's weather. Photos are credited in each pin; phenomena without a verified real photo show none. Map data © OpenStreetMap contributors.
