About the Hakkakutei Main Building
The Hakkakutei Main Building (八鶴亭本館, Hakkakutei Honkan) is a two-storey timber inn building of the early Shōwa period on the shore of Hakkaku Lake in Tōgane, Togane City, Chiba Prefecture, registered as a Registered Tangible Cultural Property on April 28, 2009. With a building area of 414 m², it is the largest of the five registered buildings at Hakkakutei.
The Hakkakutei Main Building occupies the northwest part of the site, on the south side of the road along the lakeshore. Its roof combines several hip-and-gable sections covered in pantiles. On the ground floor are a 60-mat banquet hall, the entrance and a serving room; the upper floor holds guest rooms. It was the building that served both feasting and sleeping.
The Agency for Cultural Affairs dates it to the early Shōwa period and records alterations around 1955 and in 2005. The New Building adjoins it on the east.
Why the Main Building Was Registered
The Hakkakutei Main Building was registered as a structure that has become a model of its type. What the agency singles out is the care lavished on the upstairs guest rooms.
Each room on the upper floor has a small lean-to roof over its own entrance. With a little roof marking every door along the corridor, the rooms read almost like separate cottages set inside the building. The alcoves were treated with the same care: Togane City notes that prized timbers were used for the alcove posts, the alcove sills and the lintels above, and that no two rooms share the same ceiling design.
Rather than repeating one standard room, the builders varied the wood and the details from room to room. That attention to each guest room is what sets the upper floor of the Hakkakutei Main Building apart.
Ceilings, an Entrance and a Long Roof
The banquet hall on the ground floor measures 60 tatami mats. According to Togane City, its coffered ceiling is made of Yakusugi, the cedar of Yakushima island, from trees more than 1,000 years old. Sit in the middle of the room and follow the grain from panel to panel across the grid.
The entrance has its own story. Togane City records that after the Second World War it was remodelled by Nakamura Sotoji, a Kyoto carpenter known for buildings in the Sukiya-zukuri manner, who in 1955 worked on the villa of former prime minister Yoshida Shigeru at Ōiso in Kanagawa Prefecture. So an inn built by a local master carpenter gained an entrance shaped by one of Kyoto's best-known craftsmen.
From the lakeshore road, the Hakkakutei Main Building sits lower than the three-storey New Building next door, its hip-and-gable roof spreading sideways. Seen together, the broad, low main roof and the taller neighbour make a clear contrast.
Seeing the Main Building
The interior of the Hakkakutei Main Building can be seen on the irregular public open days and events run by the volunteer group Minna no Hakkakukan. The banquet hall is also used for study meetings and small markets. As the building is not open every day, check the group's website for open days before you go (checked October 2026).
The exterior can be viewed from the road along Hakkaku Lake. The group's activity reports mention a roof leak found in Hagi-no-ma, one of the upstairs rooms, and repairs by volunteers. Directions and general visiting conditions are on the Hakkakutei page.
