The only sanctuary kept indoors
Sumiyoshi Taisha Omotosha Main Hall (住吉大社末社侍者社本殿) is a sanctuary of 1822 set inside the Omotosha Worship Hall and Offering Hall at Sumiyoshi Taisha in Sumiyoshi Ward, Osaka, registered as a Registered Tangible Cultural Property on 2018/05/10. It is one bay square, with a hipped-gable front, a plain gabled rear and a cypress-bark roof, and its floor area is just 1.5 square metres.
According to the official description it is the only sanctuary in the grounds housed indoors. Every other subsidiary shrine stands in the open; Omotosha alone sits inside a building. It enshrines the first high priest, Tamomi no Sukune, and his wife Ichihime, and by old custom inspected the offerings before they went to the main halls, which is why it shares a building with the offering room.
Fine detail at tiny scale
The roof is unusual: hipped-and-gabled at the front, a simple gable at the back. Side screens stand at the ends of a veranda with a railing, and seven wooden steps lead up to it. The brackets are simple boat-shaped blocks, the gables are latticed and hung with a pendant of the same pattern as the main halls, and the details are richly decorated with metal fittings.
At 1.5 square metres it is smaller than a single tatami mat, yet it has seven steps and the same gable pendant as the main halls. Because it is indoors and protected from weather, its bark roof and metalwork are well preserved, which is part of what makes the Sumiyoshi Taisha Omotosha Main Hall worth seeing.
It was built twelve years after the main halls were rebuilt in 1810, in the same year as the surrounding hall, so building and sanctuary were completed together. The worship hall was renovated in 1930, but the sanctuary is registered as the 1822 original.
What to look for, and visiting
The Sumiyoshi Taisha Omotosha Main Hall stands at the far end of the worship room, so you see it head-on: take in the hipped-gable front, the railing, the steps, the pendant and the metal fittings in turn. The gabled rear is hard to see from the front.
The worship hall sits on the boundary between the main sanctuary and the Shinkan zone and is open for worship during opening hours, at no charge. Omotosha is popular today with visitors praying for a good match. The festival is on March 5. Opening hours and directions are on the Sumiyoshi Taisha page.
