The Former Noma Post Office: A Seaside Landmark on the Chita Peninsula
On the Ise Bay side of the Chita Peninsula, in the town of Mihama, a compact wooden building with a steep grey roof and a pair of pointed dormer windows stands along National Route 247. This is the former Noma Post Office, finished in 1931. For close to half a century it handled the letters and parcels of the Noma district, and although it stopped doing so in the late 1970s, it has never left its corner of the village.
The building is unusually small for something that earns a place on a national heritage list: a single story with a partial upper floor, a footprint of roughly 95 square metres. What gives it weight is not size but survival. Modest rural post offices of the early Shōwa era were built in their thousands and demolished in their thousands. Few are still standing where they were put up, still looking much as they did, in a fishing and shipping town that once sent thousand-koku cargo ships up and down the Japanese coast.
From a Merchant's House to a Village Post Office
Postal service came to Noma through a local merchant. In 1880 Morita Isuke, who ran a shipping agency and a miso and soy-sauce business, turned part of his own house into an office and opened the district's first post office, becoming its first postmaster. The post moved and was rebuilt more than once over the following decades. The building registered today dates from 1931, and accounts differ on exactly which generation of the office it represents, but its role is clear enough: it served as a third-class post office and later as a collection-and-delivery branch, in continuous postal use for around forty-seven years until roughly 1978.
Noma itself had grown wealthy on the sea. In the Edo period it was a port for the sengokubune, the large coastal freighters that carried rice and goods between the regions, and the prosperity of that trade is part of why a small village could afford a building this finished. The post office sits within easy reach of the harbour and the main road, exactly where the comings and goings of a port town would have passed it every day.
What "Registered" Means Here
In November 2015 the building was added to the national list as a Registered Tangible Cultural Property (tōroku yūkei bunkazai). For visitors used to the headline categories of National Treasure and Important Cultural Property, the word "registered" is worth pausing on, because it points to a different system.
National Treasures and Important Cultural Properties are designated. Designation is the older, stricter route, reserved for items judged to be of the highest importance to the country, and it comes with firm controls on what an owner may alter. Registration is a lighter framework, brought in by a 1996 revision of the law specifically to protect the enormous stock of more ordinary buildings from the Meiji period onward (schools, shops, houses, bridges, offices) that were vanishing faster than the designation system could ever cover. Registered buildings stay in everyday ownership and use; owners are encouraged, not heavily compelled, to maintain them.
The Noma Post Office qualified under the criterion that it contributes to the historic character of the national landscape. It was the first property in Mihama to be registered, and it joined the list on the same day as another Chita Peninsula building, the former Okada Clinic.
Two Faces: Western Street, Japanese Sea
Stand on the road and the post office reads as a piece of restrained Western design. The walls are sheathed in horizontal weatherboarding, the windows are double-hung sashes that slide vertically, and the whole composition is trim and symmetrical rather than showy. The most memorable feature is the roofline. The main roof and the small porch roof projecting at the centre of the front are both treated as half-gables, where the gable end is clipped back at the top instead of rising to a full point. Above the entrance, on either side, sit two gabled dormer windows. A small ornament crowns the ridge. The roof is recorded by the Agency for Cultural Affairs as slate; some local accounts describe it more precisely as slate laid in a diamond pattern.
Then walk around. The rear of the building, the side facing the sea, is built in a plainly Japanese manner. This split personality — a Western shopfront to the street, a Japanese structure behind — was a common and practical compromise in provincial Japan of the period, and seeing both halves in one short circuit of the building is the real reward of a visit.
The Building Today
Postal work long ago shifted to a newer office next door, and the old building has been given a second life. It now carries the name Taisōkanpodō and is used as a venue for events: chamber concerts, a violin recital, even a rakugo storytelling evening have all been held inside. Much of this has come from the postmaster's family, who have championed the building's preservation and kept it open to the public on selected occasions rather than letting it stand empty.
The exterior is the main draw for a casual visitor, and it can be seen from the road at any time. The interior is not generally open; the most reliable chance to step inside is the autumn "Aichi Architecture Expo" (Aitate-haku), an annual event run by the prefecture's association of registered-building owners, when dozens of normally private cultural properties across Aichi open their doors for guided viewing.
Around Noma
The post office sits in a corner of Mihama that rewards a half-day of wandering. A short way inland is Nomadaibo, formally Ōmidōji, the temple traditionally said to hold the grave of Minamoto no Yoshitomo, father of Minamoto no Yoritomo, who founded the Kamakura shogunate. On the coast stands the Noma Lighthouse (Nomazaki Lighthouse), put up in 1921 and the oldest in Aichi; its tidy white form has made it a popular spot for couples, who leave padlocks on a nearby monument. Between them lie quiet swimming beaches and views west across the bay, which catch the sunset directly.
The nearest station is Noma on the Meitetsu Chita New Line, reachable from central Nagoya, with the post office a walk from there along Route 247. By car, the Mihama interchange on the Minamichita Road is the usual exit.

Q&A
- Can I go inside the building?
- The exterior can be viewed from the public road at any time and is the main attraction. The interior is not regularly open. The most dependable opportunity to enter is the annual autumn Aichi Architecture Expo, and the building is also used now and then for concerts and other events.
- How do I get there?
- Take the Meitetsu Chita New Line to Noma Station, which connects to central Nagoya; the building is within walking distance along National Route 247. Drivers usually leave the Minamichita Road at the Mihama interchange.
- What is the difference between a "registered" and a "designated" cultural property?
- Designation (used for National Treasures and Important Cultural Properties) is the older, stricter system for items of the highest importance, with tight controls on changes. Registration, introduced in 1996, is a lighter system meant to protect the much larger number of everyday historic buildings while keeping them in ordinary use. The Noma Post Office is registered, not designated.
- Is there an admission fee?
- Viewing the building from outside is free. Special openings and events run by the owners or organisers may have their own conditions, so check ahead if you hope to see the interior.
- What else is worth seeing nearby?
- Nomadaibo temple, linked to the grave of Minamoto no Yoshitomo; the Noma Lighthouse, the oldest in Aichi, dating from 1921; and the swimming beaches along the Ise Bay shore, which face the sunset.
