Wonderful experience camping in Kozu-shima https://www.google.com/search?q=%E7%A5%9E%E6%B4%A5%E5%B3%B6&source=lnms&tbm=isch&sa=X&ved=2ahUKEwj7_dOZhsTnAhWB-2EKHWk4CWoQ_AUoAnoECBQQBA&biw=1920&bih=937 Kozu-shima is an island way far from main land of Japan although it's a part of Capital, Tokyo. High-speed vessels are not operated in off season, so my husband and I had no choice but to take 10 hours- large passenger ship from Tokyo- takeshiba terminal (in main land) to the island. We like boat/ferry trip, so taking long time was not big deal for us... this is what I was thinking before boarding. We enjoyed cruising looking at the twilight of Tokyo-bay about for the first 30 minutes and gradually came to know the day was not good for me. I get motion sickness easily but I was thinking this big ship would not roll so heavily and I could stay without sea sickness. At last, I was sleeping whole the time on the ship because sea wave was very heavy that day and the ship rolled violently. I have to go now and will continue this article later.
