The Nihon Bijutsu Tōken Hozon Kyōkai (NBTHK) is an organization that works with the preservation of antique Japanese swords as well as promoting Japanese sword culture and studies. Established in Japan shortly after WWII, it has since existed as an organization that is authorized and supported by the Japanese government.

Among the responsibilities of the NBTHK is the preservation of Japanese swords, research, and classifying them as well as insuring their authenticity.

When it comes to the certification of authenticity of Japanese swords, the NBTHK is the highest regarded institution in Japan.

Another of its many purposes is educating admirers of the Japanese sword and its many fittings, both domestically and abroad. Additionally, the organization is also in charge of The Japanese Sword Museum, which has a lot of culturally important swords on display for its visitors, some of the blades being national treasures.

The NBTHK has its head office in Yoyogi, Tokyo.
