Pilgrimage groups formed among neighborhoods and occupations and they sent delegations to Oyama every year to pray on the group's behalf. It took 2 to 3 days to walk from Edo/Tokyo.

Mt. Oyama became a destination for fun besides religion. Along the Koma-sando, you can see these many stone monuments and plaques engraved with the names of pilgrims and pilgrimage groups who worshipped on Oyama. Lots of names everywhere on this mountain.
