It has been pointed out that the katakana translation of accessibility itself may be difficult to understand. It is also necessary to consider that even if it says "accessibility compatible", it is not easy for everyone to understand.

In the absence of clear standards, there are cases where the expression "accessibility is taken into consideration" is used even if sufficient accessibility is not ensured.In order to respond according to the actual situation, it is not only accessibility of knowledge, but improvement with persons with disabilities (feedback) Need to be done.

Accessibility in buildings

It means that anyone, including the elderly and people with disabilities, can use the building and the route to the building without any problems.Since a building can be used only after consideration is given to urban design such as the movement route to the building, it is desirable to consider accessibility not only to the building but also to the route to the building use.However, in the process, security may be reduced, so depending on the situation, a new barrier may be set up, and in the end, the facility may not be available without the assistance of the facility manager (for example, the facility). It is not desirable to enter insideBicycleLight vehicles such asKick boardTo block the passage of playset such aswheelchairThere is a fence on the slope for prohibition of traffic and it is locked).Act on promotion of facilitation of movement of elderly people, persons with disabilities, etc.See also (New Barrier-Free Law).

Accessibility in services

It means that anyone, including the elderly and people with disabilities, can use services such as subsidies and subsidies without any problems, or the degree to which they can be used.Since the benefits of using a service have a utility value only when the benefits of using the service exceed the time and effort required to enjoy it, accessibility is evaluated from the point of view of the benefits of using the service.
