【Ship Stamps】 This is the ship stamp for the Hakkoda Maru, the No. 97 ship of the Seikan Ferry. To prevent folding, it will be shipped with cardboard reinforcement. Ship stamps are the ship version of Goshuin, which are collected during visits to shrines and temples. Each company participating in the project issues stamps, which are sold at ports and on ships. The designs of the stamps express the characteristics of each company, and depict symbols of routes, ships, and tourist destinations. The ship journey to collect ship stamps is called "Ship Stamp Pilgrimage." This project started in April 2021 as an officially recognized project of the Japan Passenger Ship Association. #HakkodaMaruShipStamp
