    When I looked up at the sky, I saw a sky full of stars—it truly cleansed my soul. In the darkness, with only the sound of the waves, being enveloped by the starlight made me feel strangely at peace. The guide’s stories about the constellations were so romantic; it was such a wonderful night that I found myself wishing I could stay in that moment forever…

    The ocean is unbelievably beautiful, and no matter where you look, there are Instagram-worthy spots everywhere! From the moment I jumped into the water from the boat, I was greeted by the vibrant scenery of the coral reef—I lost track of time and just wanted to keep snapping photos☆ It’s a truly wonderful place where unspoiled nature remains♪

    The boat ride was smooth. The mangrove scenery was just as I’d imagined, and I was able to enjoy a relaxing time. However, the sun was strong, so it’s a good idea to take proper precautions against sunburn. Getting the photos was a great keepsake.

    I was so moved by the island’s abundant nature the last time I visited Kohama Island, so this time I decided to join a night tour. After sunset, the quiet island takes on a completely different atmosphere from daytime, and you can hear the sounds of rare creatures right beside you. Thanks to the guide’s detailed explanations, I was able to gain a deep understanding of the island rather than just observing it. I also appreciated that I could participate without having to bring anything.
