History and Origins of Seirai-in Temple
From Founding to the Present
Seirai-in Temple, also known as Koshōzan Seirai Zen-in, was founded in 1428 by Zen Master Getsusō Giun. As a Soto Zen temple, it enshrines a statue of Shakyamuni Buddha as its principal image.
Seirai-in Temple, which has preserved its Buddhist traditions in Hamamatsu for approximately 600 years since its founding, played an important role as a temple associated with the Tokugawa family from the Sengoku period to the Edo period. It is particularly known for its deep connection to Tokugawa Ieyasu as the family temple of Tsukiyama Gozen.
Relationship with Tsukiyama Gozen (Sena-hime)
The most historically significant reason for Seirai-in Temple is that it houses the tomb of Tsukiyama Gozen, the principal wife of Tokugawa Ieyasu. Tsukiyama Gozen was born as the niece of Imagawa Yoshimoto and married Ieyasu (then Matsudaira Motoyasu) while he was a hostage.
Tsukiyama Gozen bore Ieyasu two children, Nobuyasu (Matsudaira Nobuyasu) and Kamehime, but tragically met her end in 1579 when she was murdered by Ieyasu on the orders of Oda Nobunaga. Her turbulent life has been the subject of many historical dramas and novels.

To Deepen Your Understanding of Seiraiin Temple’s Charm
Learning About Tsukiyama Gozen
Having some background knowledge about Tsukiyama Gozen’s life before visiting Seiraiin Temple will make your visit more meaningful.
Tsukiyama Gozen (Sena-hime) was born as the niece of Imagawa Yoshimoto and married Matsudaira Motoyasu (later Tokugawa Ieyasu), who was a hostage in Sunpu. After the Battle of Okehazama, when Ieyasu became independent from the Imagawa family, Tsukiyama Gozen found herself caught between the two sides.
Her son, Nobuyasu, married Tokuhime, the daughter of Oda Nobunaga, but the relationship between Tokuhime and Tsukiyama Gozen deteriorated. Ultimately, Nobunaga issued an order for the execution of Tsukiyama-gozen and Nobuyasu, and on August 29, 1579 (Tensho 7), Tsukiyama-gozen was killed in Koyabu Village, Shikichi District, Totomi Province (present-day Tomizuka-cho, Naka Ward, Hamamatsu City). She was 38 years old.
This tragic incident continues to attract the attention of many people today as a symbol of women who became victims of the politics of the Sengoku period.
