Nojimasaki Lighthouse stands at Cape Nojima in Minamiboso City, Chiba Prefecture, overlooking the Pacific Ocean. It has an important place in the history of Japan’s modern Western-style lighthouses.
The large, white, octagonal lighthouse is one of the lighthouses whose construction was agreed upon under the 1866 Edo Treaty, concluded between Japan and the United States, Britain, France, and the Netherlands. It has been selected as one of Japan’s 50 Best Lighthouses and is also registered as a National Tangible Cultural Property.
Located within the Minamiboso Quasi-National Park, the lighthouse is both an important historic structure and a popular sightseeing destination where visitors can enjoy spectacular views of the Pacific.
Nojimasaki Lighthouse is an active navigational aid standing in a scenic location overlooking the Pacific Ocean. It has been assigned both an international identification number and a Japanese navigational aid number.
The area around the lighthouse is rich in natural beauty and includes various tourist facilities. In addition to its role in maritime navigation, the lighthouse is valued as a historic structure representing the development of modern lighthouse technology in Japan.
Nojimasaki Lighthouse was one of eight lighthouses whose construction was agreed upon under the 1866 Treaty for the Revision of Tariffs, commonly known as the Edo Treaty, between Japan and the United States, Britain, France, and the Netherlands.
These treaty lighthouses played an important role in improving maritime safety as international shipping expanded around Japan during the late 19th century.
Nojimasaki Lighthouse was first lit on January 22, 1870, following Kannonzaki Lighthouse as the second Western-style lighthouse in Japan to begin operation.
It was constructed under the guidance of French engineer François Léonce Verny. The original lighthouse was a white, octagonal brick structure standing approximately 30 meters tall. It was equipped with a French first-order Fresnel lens, an advanced optical system developed to project a powerful beam of light over a long distance.
The original lighthouse was severely damaged in the Great Kanto Earthquake of 1923 and collapsed from a point approximately six meters above ground level.
A temporary lighthouse was installed while reconstruction was carried out. In 1925, the present octagonal lighthouse was completed using white concrete.
The lighthouse suffered significant damage during the Pacific War but was restored after the war. Over the following decades, additional maritime facilities were installed, including a radio direction-finding station and a ship weather information service.
These facilities were gradually discontinued, and from 2006 onward, the former operational facilities were closed. Today, Nojimasaki Lighthouse continues to serve as a popular tourist attraction as well as a historic landmark.
The lighthouse has an attached exhibition room known as Kirarin-kan. Visitors can learn about the history, functions, and importance of lighthouses in Japan.
The exhibits include valuable historical materials, such as a second-order Fresnel lens that was once used in lighthouse operations.
Various pieces of historic lighthouse equipment are displayed outdoors around the lighthouse. These include a fog signal horn and a buoy electromagnetic horn, allowing visitors to learn more about the technologies once used to support maritime navigation.
Nojimasaki Lighthouse is an open-to-the-public lighthouse, allowing visitors to enter the tower and climb to the observation area. The admission fee was 300 yen for adults as of November 14, 2021.
On Lighthouse Day, November 1, the lighthouse is opened free of charge, attracting many visitors.
One of the highlights of visiting Nojimasaki Lighthouse is the magnificent panoramic view of the Pacific Ocean.
From the top of the lighthouse, visitors can look out over the surrounding coastline and see large ships sailing toward Tokyo Bay. The views also extend toward the Shirahama Onsen resort area and Shirahama Nojimasaki Park, making the lighthouse an excellent viewpoint for enjoying the scenery of southern Chiba.
From Tateyama Station on the JR Uchibo Line, take a bus bound for Awa-Shirahama and get off at either Nojimasaki Lighthouse Iriguchi or Nojimasaki Lighthouse-guchi.
Direct buses, including the Boso Nanohana-go, also operate from Tokyo Station, providing a convenient option for visitors traveling from central Tokyo.
When traveling by car from Tokyo, visitors can use the Tokyo Bay Aqua-Line and the Tateyama Expressway, exiting at the Tomiura Interchange. From there, approach the lighthouse via National Route 410 and the Boso Flower Line.
Free parking is available in the surrounding area.
Several sightseeing spots can be found around Nojimasaki Lighthouse. These include Roadside Station Shirahama Nojimasaki, Shirahama Onsen, and Shirahama Beach.
Visitors may also wish to explore Itsukushima Shrine and the Shirahama Oceanographic Museum of Art, making it possible to combine the lighthouse with other attractions in southern Minamiboso.
Nojimasaki Lighthouse combines an important place in Japan’s maritime history with the natural beauty of the Pacific coast. As one of the historic treaty lighthouses built during Japan’s transition to modern Western-style navigation, it offers an opportunity to learn about the development of lighthouse technology and maritime safety.
At the same time, its white octagonal tower and sweeping ocean views make it one of southern Chiba’s memorable sightseeing landmarks. A visit offers the chance to experience both Japan’s maritime heritage and the spectacular coastal scenery of Minamiboso.
