In the beautiful blue sea between the Shimabara Peninsula and the northern point of Amakusa Shimoshima Island lives a pod of around 200 wild Indo-Pacific Bottlenose Dolphins (Tursiops aduncus). 🔗 These dolphins are a year-round resident population, making Amakusa one of the rare places in the world where wild dolphins can be encountered throughout all seasons with exceptional reliability. 🔗
The Indo-Pacific bottlenose dolphins of Amakusa inhabit the waters off Tsujishima Island in Itsuwamachi Town, specifically in the Hayasakiseto Strait between Nagasaki and Kumamoto Prefectures. 🔗 The undulating sea floor and strong tidal currents create rich feeding grounds filled with small fish, providing the dolphins with a sustainable year-round habitat. 🔗 This abundance of food resources has enabled the population to remain resident rather than migrating, a phenomenon that is considered rare globally. 🔗
Scientific research has documented this population extensively. Population size estimates in 2007 and 2008 were 230 individuals (CV = 2.5%) and 216 individuals (CV = 2.1%) respectively, based on mark-recapture techniques. 🔗 A total of 172 individual dolphins have been photo-identified, representing most members of this population, with mean group sizes exceeding 100 individuals. 🔗
The Indo-Pacific bottlenose dolphin is generally smaller than the common bottlenose dolphin, with an average length of 2.6 meters (8.5 feet) and weight up to 230 kg (510 pounds). 🔗 These dolphins are characterized by their friendly and active personalities, frequently jumping out of the sea, catching fish, and swimming playfully alongside boats. 🔗 Man and dolphin have long lived in harmony in this area, contributing to the dolphins' calm and tender disposition toward boats and visitors. 🔗
The Roadside Station Amakusa Dolphin Center serves as the primary hub for dolphin watching tourism. 🔗 Located in the northern part of Shimoshima, the largest island in Amakusa, this comprehensive facility includes tour booking services, a VR area for experiencing wild dolphin encounters, a seafood restaurant, and a local specialty products shop. 🔗 The center operates as both an information station and departure point for dolphin watching cruises, providing visitors with educational resources about dolphin ecology before embarking on tours. 🔗
Cultural & Ecological Significance
Amakusa's dolphin watching experiences are part of the broader Unzen-Amakusa National Park, where conservation and sustainable tourism practices protect these marine mammals while allowing meaningful wildlife encounters. 🔗 The year-round resident population represents a globally rare phenomenon, with most wild dolphin populations being migratory.
The harmonious coexistence between humans and dolphins in Amakusa waters reflects centuries of mutual respect. Local fishing communities and dolphin tourism operators have developed sustainable practices that maintain this delicate balance, ensuring the population's continued health and accessibility for future generations.

The Dolphin Watching Experience
Pre-Tour Activities at the Dolphin Center:
Before boarding, visitors can explore the Roadside Station Amakusa Dolphin Center's educational facilities. The center features a VR area where guests can experience virtual dolphin encounters and learn about dolphin ecology and behavior. 🔗 Educational displays provide context about the resident dolphin population, conservation efforts, and the unique ecological conditions that support this year-round habitat.
The Boat Tour:
Tours depart from the Roadside Station Amakusa Dolphin Center and quickly reach the prime dolphin habitat in Hayasakiseto waters. Within just 5-10 minutes of departure, visitors typically encounter the first dolphins. 🔗 As the boat approaches the dolphin grounds, groups of dolphins become visible jumping offshore, with schools ranging from dozens to over 100 individuals swimming together. 🔗
The Indo-Pacific bottlenose dolphins of Amakusa are notably friendly and curious. When boats approach, the dolphins actively surface and perform for visitors, displaying their natural behaviors including jumping, fishing, and playful swimming alongside the vessels. 🔗 Sometimes 50 to 200 dolphins gather and migrate together, creating spectacular viewing opportunities that are rare for such large schools. 🔗
The dolphins are calm and tender in their interactions, having coexisted harmoniously with humans in this area for generations. 🔗 Observers can watch dolphins catching fish in their natural habitat, leaping from the waves, and engaging in social behaviors with other pod members. In winter months like November, dolphins particularly enjoy playing with the waves when big swells hit Amakusa, offering dynamic viewing experiences. 🔗
Boat Facilities:
Tour boats are designed for passenger comfort across all age groups. Vessels are equipped with toilets and air conditioning, making them suitable for elderly visitors, women, and children. 🔗 Boats feature covered seating areas with roofs and provide free raincoats if needed during wet conditions. 🔗 The boats safely navigate the rapid waters of Amakusa while maintaining respectful distances from the dolphins.

Important Notes
Conservation Context:
The Amakusa dolphin population faces conservation challenges. Scientific research (2007-2008) documented 12-14 dolphin deaths annually from bycatch in bottom-set gillnets, considered unsustainable for this local population of approximately 200 individuals. 🔗 This represents approximately 6-7% annual mortality from fishing-related deaths alone. Responsible tourism that follows wildlife viewing guidelines supports conservation efforts by demonstrating the economic value of living dolphins versus consumptive uses.
Indo-Pacific bottlenose dolphins are classified as "Near Threatened" on the IUCN Red List globally. 🔗 The Amakusa population's year-round resident nature and limited geographic range make it particularly vulnerable to local threats including fishing gear entanglement, marine pollution, and habitat degradation.
Weather Cancellations:
November weather can be unpredictable. Tours operate in light rain but cancel during storms or high seas. 🔗 Operators provide advance notification of cancellations when possible. The 99% dolphin sighting guarantee only applies to completed tours - weather cancellations receive refunds, not the free return ticket. Plan flexible schedules allowing potential rescheduling if traveling during winter months.
Physical Accessibility:
While boats are designed to accommodate elderly visitors and children, boarding requires navigating gangways and boat stairs. 🔗 Guests with significant mobility limitations should contact operators in advance to discuss specific accessibility needs and boat configurations. Wheelchairs may not be accommodated on all vessels due to safety regulations and boat design.
Return Guarantee Details:
The 99% encounter rate comes with a unique guarantee: if dolphins are not spotted during a tour (1% probability), participants receive a free ticket to return another day. 🔗 This guarantee requires proof of the unsuccessful tour and may have specific terms varying by operator. For November 1 stopover visitors continuing to Beppu, the return ticket may have limited practical value unless planning future Kyushu travel.
