At Yuzawa Nakazato Forest Adventure you can climb wooden and rope bridges high up in the trees before zip-lining back down to the ground. Everyone wears a harness with a belay system, so you're safe at all times, and the staff give a comprehensive explanation of how everything works. At the start of the course there's also a practice area where you can get comfortable with how to move from tree to tree.
Forest Adventure has a beginner course (Canopy Course), which is for anyone over 110cm, and an advanced course (Adventure Course), which requires children to be at least in the 4th grade and over 140cm. We tried the Canopy Course, which has 4 different routes, and spent about an hour and a half there. We had a great time, and though at first it is a little scary to be up so high above the ground, the harness makes you feel so safe that you'll quickly stop worrying and just have fun! The website below (no English) has additional photos and few video clips.
The Forest Adventure operates from the end of April until early November. Reservations are required in advance (phone number is on the homepage). The price for the Canopy Course (kids and adults) is 2,800 yen.
