A fulfilling short cruise where you can learn about nature and history. Cruising in a quiet bay, anyone can use it casually without worrying about seasickness and getting wet clothes.

While watching the origin of the place name of the “Aburatsubo”, the rise and fall of the Miura family related to the local area, and the marine research on the Aburatsubo, we visited the highlights of the Aburatsubo from the sea.
