[Social Issues/Customer Issues/Requests] ・ To communicate the historical, architectural, and spiritual significance of the castle tower, which is the symbol of recovery from the Kumamoto Earthquake. We also want to convey that Kumamoto Castle, which has historically suffered numerous natural disasters, has been revived by the recent earthquake. ・ Focusing not on the whole Kumamoto Castle, but on the "Kumamoto Castle donjon," displays content of the surrounding facilities and the division of roles, cooperation and complementation should be attempted. Since the preservation environment in the castle tower is limited, displays of the actual castle tower should not be done in principle, and historical displays of the castle tower after the Seinan War should be added, which was not done in the past. ・ From the perspective of Universal concept design, displays should be enjoyed by a wide range of people by introducing a touch displays and multilingual audio guides. We received the above request.
