Shinotsu Shrine Front Gate

A Castle Gate That Became a Shrine Gate

The gate standing at the front of Shinozu Shrine in Otsu was never built for a shrine. It began as the Kita-Ōtemon, the North Great Gate, of Zeze Castle, the fortress that once reached out into Lake Biwa just south of the modern city. When the castle was pulled down in 1870, in the first years of the Meiji period, the gate was taken apart and carried a short way inland. A ridge tablet recovered during the work records that it was reassembled at the shrine in 1872. What now reads as the modest entrance to a neighbourhood shrine is a working piece of one of the earliest castles the Tokugawa shogunate ever ordered built.

The shrine is older than the gate that fronts it. A ridge tablet dated 1456 survives among its records, placing the shrine here by the middle of the Muromachi period. Long known as a Gozu Tennō shrine, it enshrines Susanoo-no-Mikoto, a storm deity of the Shinto pantheon. Successive lords of the Zeze domain were patrons, and the present main hall was rebuilt in 1661 under Honda Toshitsugu. The gate's arrival two centuries later tied the shrine directly to the castle its patrons had governed.

Zeze Castle and Why a Single Gate Is Protected

To understand the gate, it helps to know what it once guarded. Zeze Castle was raised in 1601, the year after the Battle of Sekigahara, on the order of Tokugawa Ieyasu. It was the first of the tenka-bushin castles, built through a nationwide levy in which the shogunate required the feudal lords to supply the labour and materials. Ieyasu handed the design to Tōdō Takatora, the leading fortification builder of the age. The result was a water castle that projected into Lake Biwa, with a four-tier, four-story keep at the western corner of the main bailey. Its job was to hold the Tōkaidō highway and the crossing at the Seta Bridge, the eastern doorway to Kyoto. Alongside Matsue and Takashima, it is counted among Japan's three great lake castles.

When the Meiji government ordered the country's castles dismantled, Zeze was broken up and its gates found second lives at temples and shrines across the district. Three of its principal gates survive, and each now holds the rank of National Important Cultural Property: the main bailey gate at Zeze Shrine, the south gate at Muchizaki Hachimangū, and the north gate here. This gate received its designation in April 1924. The Agency for Cultural Affairs records it within the castle category and dates it to the Keichō era (1596–1614), in line with the castle's construction.

What to Look For at the Gate

The structure is a kōrai-mon, a gate type developed for castle defence. Its defining trait sits at the rear rather than the front. Behind the main roofed opening, two stout control posts each carry a small roof set at a right angle to the principal one, so that from the side the roofline reads as a broad central span with short wings projecting backward. A simpler gate would stop at the front roof; the kōrai-mon adds these rear roofs to shed rain off the posts and to brace the heavy doors.

Look up at the tiles. Among them you can pick out the tachiaoi, the standing-hollyhock crest of the Honda family, who held Zeze longer than any other house. In Japan a family crest, or mon, functions much like a coat of arms, and finding the Honda mark on a shrine gate is the clearest sign of where the structure came from.

The doors open inward. They are built with vertical lattice above and horizontal boarding across the lower section, and a smaller wicket gate is set beside the main opening for everyday passage when the great doors stayed shut. The roof is laid in hongawara-buki, the formal tiling that alternates broad concave pan tiles with rounded covering tiles, a finish reserved for buildings of standing. Seen together, these are the marks of a fortress entrance, not the lighter woodwork of an ordinary shrine.

Around the Shrine

The gate sits within a short walk of the places it connects to. The site of Zeze Castle is now Zeze Castle Park, laid out on the former main bailey beside the lake, with fragments of stone wall still in place and a reconstructed gate at the entrance. The other two surviving castle gates are close by: the main bailey gate at Zeze Shrine and the south gate at Muchizaki Hachimangū, so a single afternoon can take in all three. The Zeze-yaki pottery museum, devoted to the local tea ware once favoured by the domain, lies a few minutes away.

In the shrine precinct itself, a large zelkova said to be around four centuries old stands near the hall. The shrine holds its Gion festival in July, when a portable shrine is carried through the streets of the old castle town.

Naka-no-shō Station on the Keihan Ishiyama-Sakamoto Line is the closest stop, a few minutes on foot to the east. The gate faces a public street and can be seen at any hour; the shrine grounds are generally open during daylight, from around 9:00 to 17:00.
