The legend that Daikichi Taki affected construction of 1890 of the Ryouunkaku as a taskmaster has been written down in the biography of Rentaro Taki repeatedly until late years, it inspects this point, and it is following many points to become clear.
The opinion that Daikchii Taki affected construction of 1890 of the Ryouunkaku is listed in a biography of Rentaro Taki widely, but the clear grounds are not shown. There is the opinion that Daikichi Taki performed the taskmaster on the occasion of a building in 1890 of the Ryouunkaku, but it has been skeptical about before from the relations with the career of the Daikichi Taki by the building-related study. It was the investigation and repair after the Tokyo-Meiji Earthquake of 1886 that Daikichi Taki affected the Ryouunkaku. What Daikichi Taki showed as repair plan of the Ryouunkaku after the Meiji-Tokyo earthquake posted hoop iron in the window neighborhood and the trumeau and fastened it with an iron bolt and posted with metal fittings at the opposite angle of the octagon plane more. Kojiro Izumi of the original contractor of the Ryouunkaku and Daikichi Taki had the interchange since at least 1886. I can think that Izumi asked Daikichi Taki for the investigation of the Ryouunkaku which suffered from the Meiji-Tokyo earthquake of 1894 from these relations.
