Follow a line of Somei-Yoshino cherry trees along the Ohkouzu Diversion embankment for a walk that brings spring blossoms and river engineering together. The official tourism guide suggests the stretch between the Shinano River Ohkouzu Museum and Ohkouzu Bridge as a way to explore the riverside.

Why visit
These cherry trees mark more than the arrival of spring: they were planted to celebrate the achievement of the Ohkouzu Diversion works. That history gives the landscape a distinctive focus. Consider the walk for the combination of blossom-lined embankment and the river-engineering setting, rather than treating the trees as an isolated flower-viewing stop.
Plan your visit
For blossoms, aim for the usual viewing period of early to mid-April. The riverside trees can flower slightly later than those in town, so allow flexibility rather than relying on a single calendar date.
The site is in Tsubame City. The tourism guide estimates about five minutes by car from JR Bunsui Station, or about 25 minutes by car from either Nakanoshima-Mitsuke or Sanjo-Tsubame interchange. Ohkouzu Bunsui Sakura Park is listed as having parking for 160 ordinary cars.
Make the most of your visit
Use the Shinano River Ohkouzu Museum and Ohkouzu Bridge as landmarks for the suggested walk. Try taking in the embankment as a whole as well as looking closely at the Somei-Yoshino blossoms: the relationship between the trees and the diversion channel is the particular appeal here. The museum is a route landmark in this suggestion, not a promised indoor stop.
Planning notes
Official tourism information was checked on 22 October 2026. Flowering varies each year; the featured April 2020 photograph is a historical seasonal view, not evidence of current bloom or a guarantee for a future visit.
The driving times above are estimates, not a verified public-transport itinerary. Beside the river, stay on permitted paths and follow weather warnings and local barriers.
