For the Yokokuji-yato cave tombs, a Kanagawa Prefecture historic site, the Agency for Cultural Affairs database records 27 hollows spread over four tiers of hillside. Their shapes can be seen to grow simpler with the period they were built. A town survey (1990–93) confirmed 64 groups with 477 tombs in Oiso.

Oiso Saigicho is a fire festival of the Little New Year. The saito on Kitahama Beach are built by nine districts of the lower town: New Year decorations packed around a central bamboo, then wrapped in straw. It is a nationally designated Important Intangible Folk Cultural Property, designated in 1997.

The Konomachi festival is held on 5 May, the Boys’ Festival, at Mt. Kamisoroi and Oyaba. In the Zamondo rite, priests of the First and Second Shrines contest the higher seat; after three rounds the Third Shrine steps in with “until next year.” Rokusho Shrine is the provincial combined shrine of old Sagami.
