Absolutely the highlight of my trip to Japan in April 2026.
It’s in a small town of Obuse just an hour away from Nagano. The park seems to still be in construction, but you can already see a loonnnngg stretches of cherry blossoms in bloom, lining the river bank.
The yellow flower fields are gorgeous. And the best part is it’s not filled with people! So you can just take your time and explore the park thoroughly.
