Sugari no Ontachi

Sugari No Ontachi (須賀利御太刀) is a Japanese sword. It is one of the important sacred treasures of the Inner Shrine, Naikū (内宮) of Ise Grand Shrine (伊勢神宮, Ise Jingū), the Grand Head of Shinto shrines in Japan.^[1] Kotai Jingu Gishikicho (皇太神宮儀式帳) describes Sugari (須賀利) as "須賀流". "須賀流" is an archaic word for bee or wasp, which is thought to have been named for its beautiful decoration like a bee or wasp.

Since the reign of Empress Jitō at the end of the 7th century, Ise Grand Shrine has continued the tradition of Shikinen Sengu (式年遷宮), in which the shrine buildings are rebuilt every 20 years on an adjacent site with the same specifications.^[2] This tradition is based on the idea of Tokowaka (常若) in Shinto, that new objects have stronger divine power.^[3] There are 1576 sacred treasures that are renewed every 20 years, and Sugari no Ontachi is the most important sacred treasure along with Tamamaki no Ontachi (玉纏御太刀)^[4] in the sword category.^[5][2][1]

The Sugari no Ontachi was first described in the Kotai Jingu Gishikicho (皇太神宮儀式帳) compiled in 804, and it is believed that new decorations were added to the scabbard and sword fittings at each subsequent Shikinen Sengu to complete the design as we know it today.^[6] The scabbards and hanging belts of Sugari no Ontachi and Tamamaki no Ontachi were made in a characteristic style in the Heian period after the end of the 8th century.^[5][7]

A part of the name of Sugari no Ontachi", "Tachi" (太刀) is characterized by a curved blade, but the shape of the Sugari no Ontachi is similar to a straight Chokutō (直刀). As Sugari no Ontachi is used for religious services, it is much more gorgeous than swords for actual fighting. The exterior is decorated with fine gold sculptures, multiple bells, crystal, glass, agate and amber, and two crested ibis feathers.^[5]
