Located only two hours from Tokyo, Gunma Prefecture is one of Japan’s most popular destinations for outdoor sports. Operating since 2007, Minakami is the original bungy jump site of Bungy Japan. Here, visitors can jump from a 42-meter-high bridge right in front of Tanigawa mountain range, and free fall towards Tonegawa River. Aside from bungy jumping, visitors can also enjoy white water rafting, canyoning, mountain biking, and tandem paragliding. As the length of the season varies from year to year, make sure to check their website before you go.
