The Main Gate of Ryogonji
The Ryogonji Temple Main Gate (楞厳寺山門) is a thatched four-legged gate of the mid-Edo period in the grounds of Ryogonji in Imonoshima, Kakizaki Ward, Joetsu City, Niigata Prefecture, and was registered as a Registered Tangible Cultural Property (structure) on January 26, 2011 (Agency for Cultural Affairs). The temple name is also written Ryōgon-ji.
The Agency records its date as the mid-Edo period (1661 to 1751), with a repair in 1736; registration number 15-0331.
The Ryogonji Main Gate stands south of the main hall and faces south like it, serving as the temple's front entrance. Local tradition holds that it was once the rear gate (karamete-mon) of Kakizaki Castle, the stronghold of the Kakizaki clan, and was moved here.
A Thatched Four-Legged Gate
The Ryogonji Main Gate is a four-legged gate under a gabled thatched roof, 3.5 metres wide at the opening (Agency for Cultural Affairs). Two main posts carry the double doors at the center, with subsidiary posts set before and behind them.
The posts are locked together by a sill at ground level, a tie beam at waist height and a head tie at the top. On the posts sit large bearing blocks (daito) supporting a curved rainbow beam, and a frog-leg strut at the center of the beam holds up the ridge pole.
Above the front lintel (kabuki) a single short strut stands at the center. The eaves use two tiers of closely spaced rafters, and the floor is paved with square stones laid on the diagonal (shihanjiki).
Why It Was Registered
The Ryogonji Main Gate was registered for its contribution to the historic landscape. Its thatched roof, combined with careful joinery of main posts, subsidiary posts, rainbow beam and frog-leg strut, shapes the entrance to the temple.
That a mid-Edo gate repaired in 1736 still keeps its thatch adds to its value. The way the main hall comes into view as soon as you pass through the gate makes this small structure central to the historic setting of the precinct.
The Kakizaki Castle Tradition
Kakizaki Castle stood on Kizakiyama, a low hill 25 metres high in Kakizaki, and is said to have been the seat of the Kakizaki clan, who became senior retainers of the Nagao, later Uesugi, house in the Warring States period. The castle site is now ringed by roads leading to the Kakizaki interchange of the Hokuriku Expressway, and little survives (Niigata Kanko Navi).
Niigata Prefecture's tourism site introduces the Ryogonji Main Gate as the castle's rear gate by tradition, and Joetsu City's site states that it was moved from the castle. The Agency for Cultural Affairs, however, dates the gate to the mid-Edo period with a repair in 1736. Published sources do not show how the castle story fits that date.
What to Look For
Stand under the gate and look up: the load path is laid bare, from the bearing blocks on the posts to the rainbow beam, the frog-leg strut and the ridge pole above. That carefully composed temple carpentry hidden under a rustic thatched roof is the pleasure of the Ryogonji Main Gate.
The Agency describes the gate as having a bold, vigorous presence. Step back from the front to take in the heavy silhouette of the thatch, and look down at the diagonal stone paving underfoot.
Visiting the Main Gate
The Ryogonji Main Gate is the temple's entrance, and visitors pass through it on the way to the main hall. The exterior can be seen from the approach, and from beneath the gate you can study the rainbow beam and frog-leg strut at close range.
Thatch is easily damaged, so do not touch the roof or lean on the eaves. No official guidance on photography has been published; keep the passage clear for worshippers. Directions and reception hours are on the Ryogonji Temple page.
