To the house, eleven slits of light are overlapped.
Five slits adjust to the time peculiar to Ibukijima Island, that is, the solar orientation at 9:00 a.m. on the day when three traditional ceremonies are held and the day of the summer solstice and the winter solstice. When the ray of sunlight passes in the house at 9:00 a.m., the locals know the visit of the season.
Meanwhile, the lines of the natural light which go to the major cities of 6 continents (Tokyo, London, Nairobi, New York, San Paulo, Sydney) by the shortest distance from Ibukijima island also pass in the architecture.
I considered that the loals are conscious of that each one is a center of the world and Ibukijima island regains the self-respect of the once by being conscious of relation with the world.
When the relation with the world ( Internationality) is added to the identity of Ibukijima Island ( Locality), the direction of the natural light of 2:00 PM would be founded to coincide with the direction of New York and they aware that the internationality exists along the extension of the locality.
Moreover, the place where the axis of these six angles crosses is the coordinates point that indicates the position of Ibukijima island, so, the relation with the world is also the locality itself.
