Significance of conservation
and repair work

道後温泉本館

To preserve the value of cultural property and pass it on to the next generation

Since the completion of Kami-no-Yu Honkan building in 1894, over a long period of 125 years, Dōgo Onsen Honkan has repeatedly been shifted, renovated, and expanded incorporating techniques of the various eras. As a result, it now has a very complex form, with four main buildings fitted together. In response to the social demands of each era alongside the development of the hot springs, is has established itself as the symbol of Dōgo Onsen.
In 1994, Dōgo Onsen Honkan became the first bathhouse in Japan to be designated an Important Cultural Property. To pass on this historical and cultural value for the next generation to inherit and preserve, this conservation and repair work is required.

Because the Dōgo Onsen Honkan conservation and repair work requires the removal of roof tiles and copper plates during roof repairs, the entire building is covered in scaffolding.

What is the main point of conservation and repair work?
Because the Dōgo Onsen Honkan is a hot springs facility, damage to wooden parts due to moisture cannot be avoided. However, since it is a designated Important Cultural Property, simply replacing the old structure with something new would risk lowering its value as a cultural property. Extra care is taken when making repairs, as it is most important to leave the valuable materials used in the original construction, wherever possible.
What are some attractions while the conservation and repair work is being done?
Up until now, there were two men’s bathrooms but during the construction, one of them will be open as a women’s bath, so women can enjoy the men’s bath that they could not enter before.
