Usability in Japan - Building Slope-Roof - Law

Everyday Usability in Japan (Part 3)

In Part 1 and Part 2 of this series we looked at some of the intriguing aspects of the way people’s everyday lives are affected by design in Japan. Whether the result of a lone designer with a singular focus or a meddling committee with a medley of requirements it’s fascinating to see how other countries have approached the same challenges.

A big part of this includes the built landscape, and today I wanted to look at Tokyo’s ever-changing skyline which has been the result of natural disasters, war, and cultural beliefs.

Disposable Houses

  • The resale market in Japan for used houses is almost non-existent (likewise for cars)
  • Housing quality is very high but a detached house fully loses its value after 15-30 years
  • 50% of houses are demolished before they are 38 years old (compared to 100 in the U.S.)
  • Earthquakes cause people to view houses as perishable and builders play on this fear
  • Japanese society values newness as something which is spiritually clean and pure
  • There are more registered architects per capita in Japan than any other country
  • Huge demand for creatively designed homes but no economic incentive to maintain

More insight into this phenomenon on a recent Freakonomics Radio podcast episode.

Sliced Buildings

  • In Japan many mid-height buildings look like they’ve had their sides sliced off by design
  • Building regulations stipulate a slope plane that originates from the plot boundary
  • Intended to ensure that natural light can still reach the street and neighbouring properties

The law results in some very interesting shaped buildings when multiple slanted planes bisect.

Inverse Addresses

  • Most streets in Japan don’t have names, however the blocks between streets are numbered
  • Buildings within a block are also numbered in order in which they were historically built
  • Addresses are written starting from the biggest to smallest geographic entities

If that doesn’t make much sense this video by Derek Sivers should clear things up.

Queuing Culture

  • Without exaggeration, the Japanese are masters of queuing no matter how mundane
  • Whether a restaurant, train, theme park, shop, football match or shrine it’s always orderly
  • Queuing for hours becomes part of the experience of enjoying something popular or new

Surgical Masks

  • Worn by those with colds to prevent the spread of infections and show social responsibility
  • Have antimicrobial coatings which release toxic O3, killing germs such as MSRA
  • Some wear masks in an attempt to minimise effects of pollen allergies (花粉症)
