This week the theme is housing - and daily domestic life - in Tokyo and Kyoto. The centre of Kyoto is built on a grid system, and when you turn off the wide, crowded main streets, the narrow side streets are delightfully calm and residential. This is where to find the traditional Kyoto machiya wooden town houses which survived WWII. They are long and thin, often with an enclosed courtyard, and inside they are usually traditionally Japanese in style, with tatami mats, minimal decoration, exposed wooden beams, and sliding bamboo and paper partitions. Many are now being renovated and used as shops, restaurants, and places to stay.
