Notable sites:

(1) 中川番所跡 Nakagawa Ship Guard Station & Museum

Here are a few pictures of the Nakagawa Ship Guard Station, which, during the Edo era, was used to check waterway-bound trade. As I’ve cited in a previous post, “The station checked people and goods brought by barges into Edo; this included monitoring the flow of weapons to identify potential wars against the Shogunate. The station also checked the flow of women leaving Edo, as the Shogunate would take hostage the wife of each feudal lord in Edo and forbid her from going home.”

(2) 小名木川しおのみち Onagigawa River Shio-no-michi (Onagigawa Salt Road)

This river was used as a channel to transport salt during the Edo era.

(3) 宝塔寺塩なめ地蔵 Hotoji Shioname Jizo Temple

This temple has something to do with salt and the removal of warts. Seen here, bags of salt as offerings at the temple (source):

(4) 大島稲荷神社 Ojima-Inari Jinja Shrine

(5) 子安神社跡庚申堂 Koyasu Shrine ruins

Small shrine at a street corner.
