Okegawa-juku was the 6th lodging town (shukuba 宿場) on the old Nakasendo Road (中山道) that connected Tokyo (Edo) and Kyoto through an interior route passing through Saitama, Gunma, Nagano, Gifu, and Shiga Prefectures.

It was about 526 km long and had 69 lodging towns where travelers could lodge and water their horses. A few buildings from this era still remain. This Okegawa manhole has a safflower (benibana) design. Okegawa was a major producer of safflowers.
