Uchiko-cho, Ehime-ken, Japan.
Some info from Wikipedia:
Uchiko (内子町 Uchiko-chō) is a traditional town located in Kita District, Ehime, Japan.
From the end of the Edo Period (1603-1867) to the end of the Meiji Period (1868-1912), Uchiko developed and thrived as a manufacturing center of Japanese paper and Japanese wax. At that time the Yokaichi and Gokoku districts became industrialised and their historical houses still retain some vestige of Uchiko’s former glory.
In the Yokaichi and Gokoku districts is a street of merchant houses, which have solemn white or cream coloured plaster walls, lattices, decorative walls and old-style Japanese desks. This traditional street is about 600 meters long and around 90 of these historical houses are still lived in.
The campaign to preserve this old town area has been on going since 1975 and the national government designated this area as an “Important Traditional Construction Preservation Area” in 1982.
The Nobel laureate Kenzaburo Oe was born in Uchiko.
