Nomasaki Lighthouse: Aichi's Oldest Beacon, Still Lit After a Century
On a low shelf of rock where the Chita Peninsula edges into Ise Bay, a slim white tower has watched over the water since the spring of 1921. This is Nomasaki Lighthouse, though almost everyone in the area calls it simply Noma Todai. At eighteen meters it is modest beside the great coastal beacons of Japan, yet it carries a quiet distinction: it is the oldest surviving lighthouse in Aichi Prefecture, and it still performs the work it was built for.
The light first shone on 1 March 1921, during the Taishō era. The tower stands just south of Fugusaki Port, in the town of Mihama, set on a rocky reef close enough to the shore that you can walk right up to its base. Its plan is a simple circle, and its walls are built of unreinforced concrete. That phrase sounds technical, but the point is unusual: most concrete structures depend on a hidden skeleton of steel reinforcing bars, while Nomasaki has none. The walls carry their own weight as solid mass, which is why they are so thick, about 0.92 meters at the base around an outer diameter of 3.8 meters. Inside, the shaft divides into five levels.
Why It Joined the National Register
In June 2022 Nomasaki Lighthouse was added to Japan's national register of Tangible Cultural Properties. A short clarification helps here, because the country protects historic buildings on two parallel tracks. "Designated" properties, the National Treasures and Important Cultural Properties, receive the strongest legal protection and the strictest oversight. "Registered" properties belong to a lighter scheme, introduced in 1996, that recognizes buildings contributing to the nation's historic landscape while leaving their owners more practical freedom. Nomasaki was listed under that very criterion, so it is a Registered Tangible Cultural Property rather than a National Treasure.
Two qualities earned it the listing. The first is endurance. Having reached its hundredth year in 2021, the tower remains an active aid to navigation, not a retired relic kept for show. The second is how it was made. Surviving towers of unreinforced concrete from this period are scarce, and Nomasaki shows the craft of its builders in details that reward a close look: the lantern room rests on corbels shaped into clean geometric forms, and the beam-boards beneath it are cut as triangles. These are choices made by hand, in an age before such structures were standardized.
What to Look For When You Visit
The first thing most visitors notice is the shape. Nomasaki has the storybook outline that children draw when asked to picture a lighthouse, a clean white column tapering to a glassed lantern, and that unforced charm is a large part of its appeal. Against a clear sky the whole tower reads as a single bright stroke between the blue of the sea and the blue above.
Time your visit for late afternoon. The bay faces west, and as the sun drops toward the horizon the white tower catches the warm light while the water turns to color behind it. Benches set near the base invite you to slow down and stay for the change.
The lighthouse has also taken on a second life as a romantic landmark, part of a nationwide "Lighthouses of Love" project. Beside it stands a monument called Kizuna no Neiro, the "Tone of Bonds," shaped after a musical staff with no closing bar, a play on the wish for a love that never ends. Couples fasten padlocks to it and ring the nearby Bell of Bonds. Padlocks and keepsake certificates are sold at a small facility just up the road. The spot draws photographers and wedding parties, and on a clear day you may catch aircraft descending toward Centrair, the airport on its artificial island out in the bay.
One object worth knowing about is the lens. The original fifth-order Fresnel lens that once concentrated the beam was retired in 2008 when the light was converted to an LED unit, a change that cut its power draw and let it run on solar energy. After years stored elsewhere, that historic lens returned to Mihama in 2022 and is now displayed indoors near the lighthouse, where you can study its layered rings of glass up close.
Around the Lighthouse and Getting There
Nomasaki sits directly beside National Route 247, which makes it one of the easier coastal monuments to reach by car. A parking area lies on the inland side of the road; from there a marked crossing brings you to the tower. Just along the coast is a local food hall offering the area's salt soft-serve ice cream, where the original Fresnel lens is also on view, and the fish market at nearby Toyohama is a popular stop for seafood.
The tower's interior is normally closed. It became an unmanned, automated light in 1984, and as a working navigational aid it is not open for casual entry. On occasional public open days, however, a limited number of visitors can climb the internal spiral staircase, which is narrow and steep. If climbing the tower matters to you, check the Mihama tourism schedule before you travel. Reaching the peninsula is simplest by car, or by Meitetsu rail toward the Chita coast followed by a local bus.

Q&A
- Can I go inside and climb the lighthouse?
- Not on an ordinary day. Nomasaki is an active, automated light and has been unmanned since 1984, so the interior is usually closed. A few special open days each year let a limited number of visitors climb the narrow spiral stair, announced through Mihama's tourism channels.
- Is this a National Treasure?
- No. It is a Registered Tangible Cultural Property, listed in 2022. Registration is a lighter form of national recognition than the "designated" tiers such as Important Cultural Property and National Treasure, and it honors buildings that enrich the historic landscape.
- When is the best time to visit?
- Late afternoon into sunset. The bay opens to the west, so the hour before dusk lights the white tower against a coloring sky and sea. Benches near the base make it easy to wait for the moment.
- Why do people call it a lovers' spot, and what are the padlocks?
- The lighthouse belongs to a "Lighthouses of Love" project. A musical-staff monument called Kizuna no Neiro stands beside it, and couples attach padlocks and ring a small bell as a wish for lasting love. Padlocks and certificates are sold at the food hall up the road.
- How do I get there, and is there parking?
- The lighthouse sits beside National Route 247, with a parking area on the inland side of the road reached by a pedestrian crossing. A car is the simplest option; otherwise take Meitetsu rail toward the Chita coast and continue by local bus.
