【Fukuoka】Watch Japan's largest basalt sea cave up close🌊🚢

#Naturalscapes This time to see the main gate of Mustard House, I went to book an excursion boat to see 😍 Mustard gate is one of the three major basalt caves in Japan, is an erosion cave formed on the northwestern gate of Shijima Peninsula After boarding the boat, you have to put on a life jacket. After the boat stops, you can stand on the deck to see the gate of Mustard House up close, and see the largest basalt sea erosion cave in Japan at a very close distance. It is really spectacular🤩 address 819-1335 Shima Azaya 667, Itoshima, Fukuoka Prefecture
