The opening ceremonies of new bridges named “watarizome” has been conducted for centuries based on Shinto-style in Japan. Three generations of couples consisting grand-parents, parents and young couple are invited to the ceremony and walk on the bridge together as the first users in order to give hope for longevity of the structure. This paper describes about the transition and details of the ceremony base on existing documents. I expect that the set of information in this paper which was non-existent will contribute to the tradition of this unique civil engineering ceremony for the future.
