Negishi-ryu Shurikenjutsu Filmed at NINPAKU for a Nippon Budokan Overseas Video Project

Japanese kobudo, or classical martial arts, has been attracting growing interest overseas. Rather than focusing on the outcome of sporting competition, kobudo preserves techniques once connected with survival in battle and duels, together with disciplines for training the body and mind. Its many traditions include swordsmanship, jujutsu, iaijutsu, jojutsu, naginatajutsu, sojutsu and traditional gunnery.

Nippon Budokan and the Nihon Kobudo Kyokai work to preserve and promote these traditions. This year, video production is underway to introduce the appeal of Japanese kobudo to audiences overseas.

Higashiagatsuma was selected as a filming location for the segment on Negishi-ryu Shurikenjutsu. On September 18, 2026, filming took place at the Senryuin ruins of Iwabitsu Castle, Fudo Falls and Tainaikutsu Cave on Mt. Kannon, and at our own NINPAKU.

Master Yoshifumi Hayasaka demonstrated and explained Negishi-ryu Shurikenjutsu against the landscape of an authentic ninja region. We are eagerly waiting for a film that we hope will resonate with people overseas who love Japanese culture, martial arts enthusiasts, and everyone who wants to discover ninja culture more deeply.

Mt. Kannon, east of Mt. Iwabitsu, has the atmosphere of an old ninja training ground. Passing through Tainaikutsu Cave evokes a shugendo tradition of symbolic rebirth.

The timing was also special: the red spider lilies carefully tended by local residents were beginning to bloom at the Senryuin ruins. We expect the film to convey not only shurikenjutsu, but also the nature of Mt. Iwabitsu and Higashiagatsuma and the atmosphere of the area’s shugendo culture.

Master Hayasaka also serves as an adviser to NINPAKU. With guidance from one of Japan’s leading teachers of shurikenjutsu, we will continue working to welcome visitors from around the world and share ninja culture with them.
