1. INTRODUCTION | |||
Within the context of the rapid aging of its population, this chapter discusses the implications for building accessibility in Japan. The introduction of the new Accessible Built Environment Law (2006) is described, as well as how dwelling design for an aging society has progressed in the last 20 years. Japan is among the first![]() countries to succeed in persuading the general public to accept design-for-all concepts |

2. AGING AND URBANISM IN JAPAN
The notion of the emergence of an aging society in Japan is relatively new, and its consequences have rarely been taken seriously, even by the government, until fairly recently. However, Japan is becoming a society with a rapidly growing population of elderly people (National Institute of Population Problems, 1986; National Institute of Population and Social Security Research, 1997). In 1970, just 7
3. INFLUENCE OF INTERNATIONAL ACTIONS ON JAPANESE ACCESSIBILITY LEGISLATION In the past in Japan, the accessibility issue was mostly under the control of the Welfare Ministry and its departments. As early as 1974, Machida City, one of the local municipalities, issued “Design Guidelines of Buildings and Facilities toward Realizing a Welfare City,” which aimed at creating an accessible environment for wheelchair users from the welfare perspective. Although it was not mandatory, the local government tried to influence building developers as much as it could to include barrier-free design for wheelchair users in larger buildings and facilities. Although they succeeded to some extent and other local governments followed, voluntary compliance was not as effective as desired, and the move toward realizing barrier-free environments was slow. Part of the problem could be attributed to insufficient coordination in the local governments between the Buildings Control Department and the Welfare Department. 4. OVERVIEW OF THE BUILDING STANDARD LAW The new law, however, did not replace the Building Standard Law. Rather, it 5. NEW POLICIES AND INCENTIVES The government also enacted preferential interest rate schemes and subsidies linked to the law at the same time, which were expected to work as incentives. Such measures were previously enacted by some local governments, e.g., for the
6. THE NEED TO REVISE THE BUILDING STANDARD LAW TO INCORPORATE ACCESSIBILITY REQUIREMENTS The problems designers and clients are faced with due to building control are probably not unique to Japan. However, it is true that there are several limitations of the present Building Standard Law in the Japanese system. The following issues need urgent solution: 1. The assumptions about building users, as far as their capabilities are concerned, are inadequate, as pointed out in part by the Accessible and Usable
2. There is no explicitly stated established system for routine revisions. 4. While there is too much emphasis on specification requirements, the performance standards are too vague. 5. The delegation of authority to local ordinances is too restrictive.

9.THE CURRENT SITUATION REGARDING DWELLING PROVISION As stated earlier, the official design guidelines of dwellings for the aged and the Housing Loan Corporation (HLC) housing mortgage requirements emphasized three requirements: floor without unnecessary level change, support for handrail installation, and width of crucial space dimensions.The Ministry of Construction wished to have 20 percent of all dwelling units in 2015 be newly built with at least such accessible and usable features and an extra 20 percent adapted to include thesefeatures. However, the most recent result of the Housing and Land Survey conducted in 2003 revealed the following picture: Among the entire housing stock, only 5.4 percent satisfy the three requirements, and even among those units where seniors reside, only 6.7 percent satisfy the same requirements. The situation is worse with rental units compared to owner-occupied units. More recent data, surveyed inautumn 2008, are to be released soon.
10.CONCLUSIONS There are several difficulties Japan faces in order to make dwellings accessible and usable during residents’ later years. The Basic Act for Housing, enacted in 2006, lacks effective authority to enable the government to tackle and solve the problems. Generally, the act asks local governments to establish their own policy measures and priorities, yet under the current economic situation, implementation has come to a halt. It remains to be seen whether various tax incentives for new housing construction and adaptation can reverse the trend. : https://www.tdc-interior.com/blog_detail.php?lang=&blogid=46 |
