Senkakuwan Ageshima Amusement Park is a premier tourist facility located in the Ageshima Gorge area of Senkaku Bay, part of the Sado Quasi-National Park in Niigata Prefecture. The area is characterized by its dramatic scenery, where steep cliffs meet the beautiful, deep blue sea. Visitors can experience the dual charms of land and sea through various activities, such as riding a glass-bottom boat to observe the underwater world up close, exploring a modern aquarium that utilizes digital technology, and enjoying panoramic views from the observation deck.
This area has long been cherished as a place to experience the rich natural beauty of Sado. As tourism development has progressed, the site has evolved from a simple scenic viewpoint into a hub for passing down the natural heritage of Sado to future generations. The facility blends traditional nature observation with modern innovation, exemplified by the 'Agishima Sea Digital Museum,' which integrates digital technology into the study of marine life, representing a new style of sustainable tourism.

One of the greatest draws is the 'Glass-Bottom Boat' experience. By looking through the transparent bottom of the boat, you can witness the vibrant marine life and colorful coral reefs directly beneath you. Additionally, the renovated 'Agishima Sea Digital Museum' offers immersive exhibits using the latest digital technology, allowing for a deep understanding of marine ecosystems. For a breathtaking view, the Ageshima Observation Deck provides a sweeping view of the beautiful arc formed by Sado's coastline, making it a perfect spot for photography and relaxation.
The park is open year-round, though operating hours vary by season. During the summer months (May to September), the long daylight hours allow for extended activities, and the sea colors appear particularly vivid under the bright sun. Spring and autumn are ideal for gentle strolls in a mild climate. On certain occasions, the 'Agishima Light-up' event may occur, offering a mystical and enchanting atmosphere that differs greatly from the daytime scenery.

We highly recommend trying the glass-bottom boat tour to see a world beneath the waves that is invisible from the shore. At the digital aquarium, you can enjoy interactive exhibits and even interact with creatures like doctor fish. For a relaxing break, visit the 'Agishima Sea Cafe' to enjoy a beverage while soaking in the magnificent coastal scenery.
The surrounding area features iconic landmarks such as the Oozaki Lighthouse and the Yusen Bridge, which symbolize the natural grandeur of Sado. Exploring these nearby spots will deepen your understanding of the island's geography and natural formations. The park is easily accessible via driving routes from major ports like Ryotsu Port or Ogi Port, making it a perfect stop during a Sado island road trip.

While the park paths are well-maintained, we recommend wearing comfortable walking shoes for moving around the coastal areas and observation decks. Regarding payments, please check if your preferred facility accepts credit cards, as some may require cash. While there are English signs and digital exhibits, you may need to consult local staff for detailed information. Please be mindful of other visitors when taking photos. The facility is accessible, with wheelchair-friendly entrances and parking available.
