Registered Tangible Cultural Properties of Japan

Igantei is a Meiji-era guest hall built in 1912 by the prominent Hosaka landowner family in Tonome, Joetsu City, Niigata Prefecture. Registered as a National Tangible Cultural Property in 2024, it features a striking copper-plated karahafu entrance and exquisite kumiko lattice windows showcasing the finest craftsmanship of the period.

Ikinariya's rear gate, a late-Edo service gate on the hill behind the buildings, has a single lattice leaf with a sliding wicket and carefully chamfered posts.

Ikinariya's front gate of 1914 is a sukiya-manner gate with a curved copper roof and korai-mon stance, a crane emblem carved in openwork above the door.

Ikinariya's Kyuban-no-ma, an 1877 room of about 29 square meters, rests on a garden hill at the rear and tall posts at the front, projecting stage-like over the garden.

Ikinariya's Kotobuki-no-ma and Niban-no-ma, an 1877 hall and its largest registered room, sits at the back of the grounds, opening onto the pond garden for banquets.

Ikinariya's Sanban-no-ma, a compact 1877 room of about 40 square meters, pairs a kakekomi ceiling following the roof slope with a boat-bottom funazoko ceiling.

Ikinariya's main building, in a Niigata ryotei founded around 1700, is a late-Edo two-story wooden hall with an L-shaped doma, one of ten structures registered in 2000.

Ikinariya's middle gate and wall of 1928 form an inner boundary: a light gate with a natural-timber ridge, shingle roof and woven door, beside a wall by the storehouse.

Ikinariya's detached room, a 1928 wing and its largest registered structure, sets Western lamps and a natural-wood rail within a Japanese hall, cranes throughout.

A small wooden warehouse from 1910 stands at Nihongi Station, built a year before it opened. It keeps a king-post truss roof and high windows. Registered 2019.

A 1942 reinforced-concrete underpass links the building and island platform at Nihongi. Trains reverse across the main line here, so passengers cross safely below ground.

A 1937 steel roof shelters the island platform at Nihongi. Its columns reuse old rails, American ones from 1923 and Yawata Works rails from 1929, welded head to head.

A 1935 wooden waiting room stands on the Nihongi platform, glass on all sides and a timber face where red walls meet white posts. Built for snow country, registered 2019.

A brick lamp shed from 1910 stands at Nihongi, a 9.9-square-meter oil store for lamp fuel with a cornice and gable pediments. Locals call it the red-brick shed.
