Shirasuka-juku

During the Edo period, it was the westernmost post station of Tōtōmi Province.

Before the 1707 earthquake, it was recorded to have 27 inns for travelers, making it a middle-sized post station.

When the post station was decommissioned in 1889, it was replaced with the new town of Shirasuka, which later merged with the city of Kosai in 1955.

However, the train line did not come through Kosai and major developments in the area were kept to a minimum.
