Tokyo's historic Hyakudan Kaidan building reopens after 1 year

In the event, running until March 30, 2027, few exhibits are on display in the Tokyo metropolitan government-designated tangible cultural property, unlike in past events with exhibits and showcases that partially blocked views of ceiling paintings, pillars and architectural details.

"We aim to have visitors experience the architecture firsthand and directly feel its charm," the public relations office for Hyakudan Kaidan said.

Across the seven traditional Japanese-style rooms connected by a 99-step wooden staircase, visitors can find about 100 motifs associated with good fortune in paintings and architectural decorations on ceilings, walls and alcove pillars.

Among them are numerous Japanese 'sensu' folding fan motifs representing the Japanese concept of 'suehirogari,' which literally means widening toward the end like an open folding fan, and symbolizes growing prosperity, good fortune and future success.

In the Jippo room, the first room of the building, what is believed to be Japan's oldest surviving rotating table is on display.

The table, restored from a pre-World War II piece, is decorated with mother-of-pearl inlay, a traditional decorative technique in which the shimmering, silvery-white parts of shells are cut out and inlaid into the surface of lacquerware and other objects.

The architectural features and the rotating table offer insight into the history of Hyakudan Kaidan, which once served as a 'ryotei' traditional Japanese restaurant at the former Meguro Gajoen, a famous venue of lavish banquets and wedding receptions, following its completion in 1935.

Although most of the buildings in the original 1935 complex were demolished in 1988 due to redevelopment projects, Hyakudan Kaidan has been preserved largely in its original state to this day.

"As the cityscape continues to transform, the survival of Hyakudan Kaidan, nearly unchanged since the early Showa period, holds profound significance, allowing the area's history and memories to remain present within the modern landscape," the office said.
