House of Councillors (Sangiin) at the National Diet Building

Overview & Appeal

The House of Councillors offers official tours conducted by security officers (Eishi) following a designated route. These tours are available to those who have completed the registration process. The journey through the facilities, including the main chamber, takes approximately 60 minutes. This is a structured opportunity to witness the actual site of legislative activities in Japan through an official route.

History & Cultural Background

The House of Councillors is one of the two houses that constitute the National Diet of Japan. The National Diet Building houses essential facilities that play a central role in Japanese politics. The interior design utilizes special materials and techniques, reflecting both Japanese architectural skill and cultural heritage. Furthermore, there are established systems for public transparency, such as the special viewing sessions held on Sundays after the Diet session has adjourned.

Main Highlights

The primary tour route includes the viewing lobby and the House of Councillors chamber. The chamber is the central space where legislative debates in Japan take place, allowing visitors to observe its unique structure and design. The tour follows a strict path under the guidance of security officers to ensure order and safety.

Seasonal & Time-Specific Recommendations

Tours are generally held from Monday to Friday (excluding holidays and New Year's holidays) between 9:00 AM and 4:00 PM, with registration available at the start of every hour. However, if a plenary session is scheduled, tours may be suspended from one hour before the session starts until the session concludes. During school long vacations, morning tours tend to be more crowded. To avoid crowds, visiting in the afternoon is a good option. Additionally, on the 1st and 3rd Sundays after the Diet session ends, special viewings are held from 10:00 AM to 3:00 PM via applications through Diet members.
