It is National Museum that becomes the fourth in Japan built in Fukuoka Prefecture Dazaifu following Tokyo, Kyoto, and Nara. The lighting plan to connect the inside to the outside with LED buried under the floor because of light was held to the main body of the museum. Moreover, a consecutive reflected crowding from the inside to the reflection glass was made to set up LED on the glass wall, and to be able to be enjoyed outside as an accent of the facade. The sense that passes under the time tunnel is produced to the passage where Dazaifu Temmangu is connected to the museum by the movement of light with the speed feeling.
