It rained the day before our Okinawa glass-bottom boat underwater sightseeing tour, and I was worried we wouldn't see any fish. However, on the day of the tour, the weather cleared up beautifully. Upon arriving at the West Marine counter, there was a sign indicating the clarity of the water and the choppiness of the waves, which passengers could refer to. After boarding, passengers could first enjoy the coastal scenery from the top deck. When the boat reached deeper waters, staff would instruct passengers to go to the lower deck to observe the fish, and finally, they could go to the middle deck to feed the fish. This activity is very suitable for families with children. My package also included a seafood donburi on the Mobydick boat, with several types of fresh sashimi available for unlimited consumption. Perhaps there were fewer people that day as it wasn't peak season, but enjoying lunch quietly was exceptionally leisurely and relaxing.
