It started raining heavily before we even left Naha. The high-speed ferry ride took 40 days to reach the island. Thankfully, the rain wasn't too bad once we arrived, but it was very cold. Even though it was cloudy, you could still see the gradient colors of the sea. Next time, I want to come back for snorkeling and an overnight stay to experience the island's tranquility and play with the island's cats. On our way back to Okinawa's main island, we saw sea snakes, corals, and tropical fish at the harbor – probably the cleanest harbor I've ever seen. The Taiwanese staff who greeted us on the island were very kind.
The original booking time was unavailable, but we rescheduled with the staff and were finally able to go. Many thanks to them for their help. Our group included tourists from South Korea, Hong Kong, Taiwan, and Europe and America. The boat trip was quite long, but no one got seasick; everyone was quite healthy. The weather was nice, and we strolled around Aharian Beach. We had curry rice for lunch, and in the afternoon, we went whale watching. We saw whales a few times, but unfortunately, their surfacing was brief and they were quite far away. Overall, though, it was a very good experience.
Whales are hard to catch, but it was a great experience. I hope to have the chance to see a whale breaching the water next time. The staff were very thoughtful; they added me on the app the day before to confirm.
