A Pagoda Missing Its Upper Railings
Zenzanji Sanjunoto (前山寺三重塔, also romanized Zensanji or Zenzan-ji), the three-storied pagoda of Zenzanji Temple in the Maeyama district of Ueda City, Nagano Prefecture, was raised in the late Muromachi period and designated an Important Cultural Property on 13 April 1922.
The Agency for Cultural Affairs records it as sangen sanju toba: a pagoda of three bays on each side, three stories tall, roofed in kokerabuki, thin shingles of split wood laid in overlapping courses rather than tile. It carries designation number 00765 and is counted as a single structure. No inscription survives to name a carpenter or a completion date, so the Agency assigns it to the years between 1467 and 1572 on the evidence of its detailing alone.
The temple occupies a shelf of ground on the lower slope of Mount Tokko, looking north across the Shioda basin. Ueda's tourism materials call this stretch of countryside the Kamakura of Shinshu, a nickname earned by the unusual density of medieval religious architecture within a few kilometres. Temple tradition credits the priest Kukai with founding Zenzanji in 812, and records a second founding in 1331 when a priest named Choshu arrived from Zentsuji in Sanuki Province and moved the temple to its present ground. Shioda Castle stood across the valley to the west; local historians read Zenzanji as the castle's prayer temple.
An Argument About What Counts as Finished
Walk up the stone steps and the first thing that registers is an absence.
The lowest story carries a veranda (en) with its railing (koran) running the full circuit. The second and third stories carry neither. Windows and doors are likewise omitted above the first level, so the upper two tiers present nothing but plank wall, bracket and roof.
The builders had planned otherwise. Square nuki, the horizontal ties that pass through the pillars and lock the frame together, project outward at the upper levels at precisely the height where veranda boards would have rested. Other details around the structure look similarly arrested in mid-work. Something stopped the job, and nothing on the building says what.
Commentators divided over how to read that. One reading takes the pagoda at face value as unfinished. The other points out that a pagoda's upper verandas serve no function, since nobody climbs the upper floors of a pagoda, and argues that stripping away the ornament leaves the frame more legible, not less. The second reading gave the building its local name, mikansei no kansei to, the completed unfinished pagoda. Both readings agree on the quality of what stands: the stacked curves of the three roofs resolve without any sense of something lacking, and the nine rings of the finial rise above them with real authority.
The 1922 designation placed the pagoda among the earliest buildings in Nagano Prefecture to receive national protection, three decades before the neighbouring pagoda at Daihoji in Aoki Village was raised to National Treasure status in 1952.
What Rewards a Slow Look
Go to the southwest corner of the first story and look up at the head of the corner pillar. A carved kibana, the ornamented end of a projecting tie beam, pushes out to the left. Tusks and eyes have been cut into the block, an early stage in a motif that later carpenters developed into lions, elephants and the mythical baku. The eyes sit unusually high, leaving only a shallow band of surface beneath them, and that lopsided proportion earned the carving a wry nickname among Ueda residents generations ago.
The buildings that frame the pagoda are protected at a different tier. Zenzanji's main hall, its kuri (priests' living quarters), its formal entrance and its gate are Registered Tangible Cultural Properties, a lighter category than Important Cultural Property that covers structures judged worth preserving rather than nationally significant. The main hall keeps a thatched roof, now a rarity in Nagano temple architecture.
Practical matters. The precinct opens at 9:00 and closes at 16:00, and admission runs 200 yen for adults, 100 yen for high school students and 50 yen for elementary and junior high school students. Parking sits beside the gate, with a second, smaller area reserved for visitors with limited mobility. The pagoda is viewed from the grounds; its interior is not open to visitors. Notices about photography are posted at the entrance, so read them before raising a camera.
Reaching the temple takes roughly 30 minutes by car or taxi from Ueda Station on the Hokuriku Shinkansen, and about the same from the Ueda-Sugadaira interchange. Come in late April and the precinct's wisteria is out; come in November and the maples are.
One more thing worth knowing. The temple serves kurumi ohagi, rice sweets under a paste of walnuts gathered in the precinct, made by the resident priest's household. They are available April through November, the kitchen closes on Thursdays and Fridays, and reservations are required.

Q&A
- Can visitors see Zenzanji Sanjunoto, and what are the hours and admission fee?
- Yes. Zenzanji's precinct is open daily from 9:00 to 16:00, and the pagoda stands in open ground where it can be seen at close range. Admission is 200 yen for adults, 100 yen for high school students and 50 yen for elementary and junior high school students. Parking is available beside the gate.
- Why is Zenzanji Sanjunoto called the completed unfinished pagoda?
- Its second and third stories have no veranda and no railing, although the projecting tie beams that would have supported a veranda floor are in place. Some read the building as literally unfinished. Others argue that upper verandas on a pagoda are decorative, since the upper floors are never climbed, and that the building reads as complete without them. The nickname records that disagreement.
- When was Zenzanji Sanjunoto built, and when did it become an Important Cultural Property?
- The Agency for Cultural Affairs dates the pagoda to the late Muromachi period, between 1467 and 1572, based on its structural detailing, since no dated inscription survives. It was designated an Important Cultural Property on 13 April 1922 under designation number 00765.
- Can visitors go inside Zenzanji Sanjunoto or take photographs of it?
- The interior is not open to visitors, and the pagoda is appreciated from the surrounding grounds. Photography conditions are posted at the temple entrance and can change, so check the notices on arrival or ask at the temple office.
- How do visitors reach Zenzanji Sanjunoto from Ueda Station?
- Zenzanji is about 30 minutes by taxi or car from Ueda Station, which is served by the Hokuriku Shinkansen. Drivers coming off the expressway need roughly 30 minutes from the Ueda-Sugadaira interchange. The temple sits in the Shioda basin near Bessho Onsen, so it combines easily with the National Treasure pagoda at Anrakuji.
