Seitenzan Kangiin (Menuma Seiten), Kumagaya

Seitenzan Kangiin, commonly known as Menuma Seiten-gū or simply Menuma Seiten, is a Buddhist temple located in Kumagaya City, Saitama Prefecture, Japan. The temple belongs to the Koyasan Shingon sect and was originally founded in 1179 during the late Heian period. According to tradition, a farmer named Saita Bettō discovered a sacred image while plowing his field and established a small sanctuary on the site. The temple gained prominence during the Edo period and became an important pilgrimage destination in the Kantō region.

The temple's main attraction is its spectacular honden (main hall), which is designated as a National Treasure of Japan. This ornate structure was rebuilt in 1746 after a fire destroyed the original building. The hall is renowned for its breathtaking architectural decoration, featuring elaborate carvings of mythical creatures, flowers, and geometric patterns that cover virtually every surface. The building exemplifies the highly decorative style of mid-Edo period temple architecture, with intricate lacquerwork and gilding that has been carefully preserved. The craftsmanship displays techniques rarely seen in other religious structures from this period.

Visitors can explore the temple grounds, which include several other historically significant buildings and a traditional Japanese garden. The main hall houses the principal deity, Shōten-sama, a form of Kangiten, one of the Buddhist guardian deities. The temple complex also features a treasure house displaying religious artifacts and historical documents related to the temple's history. The temple is particularly known for granting wishes related to marriage, business prosperity, and removing obstacles, drawing worshippers seeking these blessings throughout the year.

Menuma Seiten is accessible from Menuma Station on the Chichibu Railway, approximately 10 minutes on foot from the station. From Tokyo, visitors can take the JR Takasaki Line to Kumagaya Station, then transfer to the Chichibu Railway. The temple is approximately 60 kilometers north of central Tokyo. Admission to the temple grounds is free, though there is a small fee of around ¥500 to enter the treasure house and view the interior of the main hall more closely.
