The tiles used on the buildings are made out of Kucha, an iron-rich mudstone unique to Okinawa that turns a beautiful vermilion color when baked! Kucha is used for its heat and humidity-controlling properties. Tiles made out of Kucha absorb moisture from the air, which serves to dissipate heat when it evaporates. This helps to make a much cooler house -- perfect for a subtropical island like Okinawa! 📷:@takao.maki #taketomiisland #yaeyamaislands #竹富島 #八重山群島 #다케토미섬 #야에야마제도 #八重山諸島 #シーサー #shisa #redrooftiles #beokinawa #visitokinawa」1月29日 16時00分
