We drove down to check out this Japan World Heritage site this past weekend. I checked prior to arrival that you had to purchase tickets. I read ¥200 for adults and ¥100 for kids. When I purchased tickets via the vending machine the price had gone up ¥100 for both adults and kids. No biggie on my end, but I want others to be prepared. You walk across the street from the welcome center and about a quarter mile before you arrive at the site. When you start your walk you will hand over your ticket and receive a brochure in your language. You can walk at your own pace and take as many pictures as you want throughout the park. We spent around an hour walking/viewing/taking pictures with our boys. Be sure and read each marker for details at each spot (there's English which is rare for most Japan sites). I enjoyed this historical site and recommend it for all interested in history. It might be difficult (mainly distance and rough terrain) for young children.
