Going to the island, the ferry ⛴️ is very convenient, there are more than 6 dozen boats in 24 hours, only 15 minutes from Kagoshima port to Sakurajima, to Sakurajima to try the ash ice cream, the same famous ~ small honey ~ ice cream, go to the left dinosaur park, there is a long slide, You can take a sightseeing bus to the nearest crater of the observatory to watch the volcano. It is an active volcano. There are a lot of them to excavate the wild. Take the left volcano charcoal back to do a hand letter. I suggest that the day trip time on Sakurajima will be loose.
