Akarengasoko was constructed from the end of the Meiji era to the early Taisho and did not meet existing conditions. Therefore, when utilizing it as a facility to be provided to an unspecified number of users, it was necessary to consider the safety of users and to meet the current seismic regulations.
The structural reinforcement that has been implemented so far has been reinforced using steel frames based on the basic policy of preserving the exterior design, making the indoor brick wall visible, and removing it as necessary in the future.
