01 ／ Former Hanawa Elementary School

Rebuilt in 1931 with a donation,a two-story wooden schoolhouse.

The school opened in 1873, and in 1931, thanks to a donation from Imaizumi Kaichiro, it was rebuilt as a two-story wooden building with a tiled, gambrel-style roof. The city notes that the roof ventilator has no other example in the prefecture. It is a nationally registered tangible cultural property.

02 ／ Kasakakeno Goyosui canal

About 66 cm in the main channel, about 36 cm in the branch.No one was allowed to alter the flow, it is said.

This is the Mitsumata diversion point, where the canal opened in 1669 by the magistrate Okanobori Kageyoshi splits the water of the Watarase River into a main channel and a branch. The present structure reproduces the one from the 1872 revival, and it is a city-designated historic site. The canal was opened to bring water to the Honmachi post town (now Ohara, Ota City).

A makeshift theater went up in 1929, and the two-story wooden theater was completed in 1937. It has a revolving stage turned by hand, and is a city-designated important cultural property.
