The Akasaka Palace State Guest House, the government’s active state guest facility that hosts distinguished guests from overseas, will hold a special four-day extended evening opening from Saturday, September 19, through Tuesday, September 22 (a national holiday). During this period, the main building will be illuminated after sunset, and the facility will remain open until 8:00 p.m.
The beautiful illumination of the classical and majestic architecture, emerging from the darkness, offers an extraordinary sight on these long autumn nights.

In addition, the “Main Entrance Hall”—which is normally off-limits to the public—will be open for a special viewing, and a special exhibition will be held inside the main building.
A “Garden Café” and “Music Stage” are also scheduled to be set up in the front garden, allowing visitors to relax while enjoying music and food and drinks against the backdrop of the illuminated historic buildings.
No advance reservation is required for general admission. It’s great that visitors can easily drop by to fit it into their long weekend plans. (Advance reservations are required for tours of the Japanese-style annex and for group visits.)
