Hado Misaki is a scenic cape located at the tip of the Higashimatsuura Peninsula in Chosei Town, Karatsu City, Saga Prefecture. As part of the Genkai Quasi-National Park, it is recognized as one of the '100 Best Beaches in Japan' and is also designated as a 'Lovers' Sanctuary.' The greatest draw of this location is the underwater observatory, which allows you to observe the sea life directly from below, and the breathtaking views of the coastline. The area also serves as a resort destination, featuring amenities such as beaches, campsites, and public lodging facilities to enjoy the great outdoors.
The area holds significant historical value. To the south lies the site of Nagoyoshi Castle, believed to have been built by Toyotomi Hideyoshi in 1592. The surrounding area is dotted with remnants of battle sites that tell the story of past conflicts. At the very tip of the cape stands an unmanned lighthouse that has long protected maritime navigation. Additionally, the presence of the 'Dol Hareubang' stone statue—a guardian deity from Jeju Island, South Korea—highlights the international cultural exchange and connections of this region.

The iconic symbol of Hado Misaki is the Underwater Observatory. Connected to the land by an 86-meter-long pier, the structure features an underwater viewing room at a depth of 7 meters. Through 24 specialized windows, visitors can observe a diverse marine ecosystem, including tropical fish like Sea Breams and various sea plants and shellfish. From the observation deck, you can enjoy a panoramic view of the islands floating in the Genkai Sea. The scenery becomes particularly dramatic during sunset, when the sky and sea are bathed in golden hues.
Hado Misaki offers different charms depending on the season and time of day. The area is bustling with people enjoying swimming, camping, and fishing during the summer months. For the most magical experience, visit during the evening to witness the sunset over the ocean. Beyond the views, the local food culture is a highlight; many visitors stop at nearby stalls to enjoy the famous 'Sazae no Tsuboyaki' (grilled Turban Shell), a delicious way to taste the freshness of the sea.
There are various ways to connect with nature here. Popular activities include observing marine life at the underwater observatory, hiking along the coast, fishing, and swimming. For those looking to stay longer, the area offers well-maintained campsites and lodging. Depending on the season, you may even encounter cultural elements related to local traditions, such as the 'Sea Tug-of-War' held at the nearby Hado Fishing Port.
The area around the cape is well-equipped with facilities to support visitors. The Hado Misaki National Lodging (Kokumin Shukusha) provides accommodation for families and groups. There are also campsites and outdoor shower facilities available, making it an ideal spot for outdoor enthusiasts. Furthermore, the nearby Karatsu area is rich in cultural heritage, such as the Nagoyoshi Castle ruins, making it a perfect addition to a scenic driving route.
