Our family visited Shirahama this time, so we only used two types of passes: "Adventure World" and "Seamore Hotel Onsen Pass." However, the cost of just Adventure World alone exceeded the price of the pass, and the Seamore Hotel Onsen was also fantastic. Another advantage of this pass is that it is valid for one week from the date of card swipe, which is very considerate of consumers.
