At Home In Japan: Beyond The Minimal House, at the Geffrye Museum, offers a fascinating peek into contemporary Japanese life. The exhibition is the brainchild of anthropologist Inge Daniels, who spent more than a year looking at 30 urban homes in the Kansai region around Osaka and Kyoto in southern Japan.
The interiors of 10 of these houses were documented by photographer Susan Andrews and form part of the exhibition, which is laid out in the style of a "typical" urban home.
Since the early 20th century, leading Western architects and designers have been seduced by the idea of the minimalist Japanese home, using it as the basis for their own designs for spare, empty spaces.
The truth about how the urban Japanese live is, according to Inge Daniels, rather different. "Since Japan opened up to the West in the 1860s, successive governments tried to encourage people to adopt western habits, from the design of interiors to the use of tables, chairs and sofas."
After the Second World War, four million new homes were needed but the country's priority was economic recovery and housing was left to private developers. By the late Nineties more than 60 per cent of Japanese owned their own homes but the dominance of five national home-building companies has resulted in a standardised look to both their exteriors and layouts.
Space is extremely expensive there, so since the Sixties the typical home has a living/dining/kitchen or a dining/kitchen area. This is a yoshitsu, a Western-style room, where the family cooks, eats and relaxes. The Japanese rarely now eat on the floor and have a simple table and chairs along with a cupboard stacked with colourful tableware in ceramic, wood and plastic. However, sitting on the floor to relax is still the norm and the sofa is often used to recline against rather than sit on.
Many homeowners like to maintain a traditional washitsu room, a multifunctional space with tatami mats made of rice straw covered in soft woven rush straw. At night children sleep here on futons, often with their mother, and by day a low table plus large pieces of "western" furniture such as desks and cupboards create a general-purpose activity space. Most homes built since the Nineties have wooden flooring throughout.
WET AND DRY ROOMS
By western standards lavatories — always separated in Japan from the bathroom — are sophisticated, including heated seats and built-in bidet systems, with hand basins cleverly located on top of the cisterns.
Bathrooms consist of two spaces — firstly a dry room with a washbasin, washing machine, a laundry basket and towel storage; here people undress before stepping into the adjacent wet room for bathing. Before entering the bath, the bather sits on a low stool, cleansing the body repeatedly with soap and rinsing thoroughly.
The bath is often the only private space for the father in the household (though he often sleeps separately from his wife). Special slippers are worn in the bathroom and the loo. Shoes are never worn inside a Japanese house but are left at the threshold and replaced by slippers.
THE LAND IS MORE IMPORTANT THAN THE HOUSE
Japanese families sacrifice larger gardens for parking. Plants are grown in pots. It is the land rather than the house that is important. "Modern Japanese houses are commodities that generally reach the end of their life after about four decades. It is common to mark the change of generations (when parents die or when children move back home to take care of them) by destroying the family home and building a new house on the same site, but not before holding a housebuilding ceremony to guard the building and its future inhabitants against misfortune."
