Kenchikushi is a national qualifica

Kenchikushi is a national qualification under the Kenchikushi Law. The Kenchikushi Law (“the
Law”) was promulgated and came into effect in 1950, and has been revised several times since
then.
The holder of the Kenchikushi qualification, referred to as a “Kenchikushi,” is licensed to provide
services such as design and construction administration*1 of buildings*2, and plays the dual role of
an architect and a building engineer. Those who intend to become Kenchikushi must pass the
qualifying examination for Kenchikushi and obtain the license through the registration procedure.
There are three types of Kenchikushi licenses (1st-class Kenchikushi, 2nd-class Kenchikushi, and
Mokuzo Kenchikushi), which restrict the use, scale and structure of buildings for which the
Kenchikushi is qualified to offer a professional service.
For buildings larger than the prescribed scale, a Structural Design 1st-class Kenchikushi*3 must
perform the structural design and an MEP Design 1st-class Kenchikushi*3 must perform the MEP
design; or a holder of the relevant qualification must confirm that the design complies with the
relevant law. (Articles 20-2 and 20-3 of the Law)
