Exploring Amami Oshima’s Underwater Wonders: A Practical Review of the Half Day Boat Snorkeling Adventure
If you’re looking for a chance to experience Japan’s lesser-known tropical waters, the Half Day Amami Japan Boat Snorkeling Adventure offers just that. For around $99, you’ll spend roughly 3 hours on the water, exploring some of the most vibrant and unspoiled marine spots of Kagoshima Prefecture. The tour departs from Ashitoku Fishing Port and takes you to Kotori Beach and either Sakibaru or Utabaru Point, known for their stunning coral reefs and abundant tropical fish.
What we love about this tour is how accessible it is — suitable for families with children as young as 4 and for more experienced snorkelers alike. The guides, Masato and Ricky, are praised for their excellent English and deep knowledge, making the experience welcoming and educational. Plus, snacks and soft drinks are included, which adds a nice touch after a refreshing swim.

This tour is perfect for travelers who want an authentic, hands-on encounter with Japan’s vibrant marine life without spending all day on the water. If you’re someone who appreciates small group sizes (max 18 people), personalized attention, and genuine natural beauty, this experience is a great match.
