Oiwake Shukuba Matsuri: The Post Town That Still Knows Its Songs

Oiwake sits at the junction of the Nakasendo highway and the Hokkoku Kaido, one of the branching points in Edo Japan's road network where travelers stopped to decide which direction to continue. The post town that served this traffic was prosperous and lively; the folk song that developed here — the Oiwake-bushi, originally sung by the horse drivers who worked the road — spread widely enough to influence regional music across central Japan.
The September festival recreates something of this history: period-costumed processions, horses, and performances of the Oiwake-bushi in a setting that preserves more of the original post town character than most Nakasendo sites. The song itself is worth knowing — a kind of measured melancholy that suits a place where roads diverge and travelers made decisions.
Oiwake is administratively part of Karuizawa, which is famous as a summer resort. The post town is a different place entirely — older, less curated, carrying a different kind of atmosphere. Finding it requires knowing it is there, which is a prerequisite for everything worth finding.
The fields around Miyota stretch flat and wide under the shadow of Asama-yama, and in summer the rows of lettuce and cabbage run almost to the edge of the road. The mountain itself — a layered stratovolcano still considered active — shapes everything here: the soil, the air, the particular quality of light that falls across the plateau. Miyota-machi sits in the fold between the old Nakasendo highway and the Shinetsu highlands, a town assembled from three villages in the mid-twentieth century, now sustained by precision machinery factories and vegetable fields in roughly equal measure.
The old post town of Odai-juku still holds its form along the former Nakasendo route — the honjin and waki-honjin survive as structures, not reconstructions. Nearby, Shinraku-ji temple occupies ground that has been in use since the sixth century, its dragon-god legend tied directly to Asama-yama's volcanic mythology. The Asama Jomon Museum, sharing a site with the town library, traces both the mountain's eruptive history and the people who lived on its slopes long before the highway existed. Jomon pottery designated as important cultural property sits in cases without ceremony.
What keeps the texture grounded is the ordinariness of the infrastructure: a single Shinano Railway station, a curling hall — privately run, used for a film shoot — and the preserved D51 locomotive at the old switchback station site. The Ryujin Matsuri moves through the calendar as a local event, not a performance. Precision components leave the factories; cabbages leave the fields. The town continues on its own terms.
