Thank you to our tour guide for your kind guidance. Actually, some people are bound to be delayed in disembarking on this kind of tour. My suggestion is that if you're going to take this tour, queue up early to disembark; it will give you a much better experience. The scenery inside is beautiful. You can buy the Miffy popcorn bucket; it's very cute.
The scenery on Kujukushima Island is beautiful, and the weather was great the day I went. The sightseeing boat trip takes about 40 minutes and the ride is very smooth. There are seats or standing room by the windows on the boat, and you can also go up to the deck to take pictures.
