@jesseogn: Exploring Akiyoshido Cave in Yamaguchi gave me the chance to see a side of nature I didn't know existed in Japan. From the massive limestone ceilings to the crystal clear river, every part of this underground tour was incredible. If you want to find unique spots like this for your itinerary, I reccomend using @JAPAN AIRLINES【公式】 quick and convenient domestic flights, plus their “JAL Guide to Japan” website. #japan #yamaguchi #japantravel #FlyJAL #PR
