Yes, the Hakone Sightseeing Cruise (Pirate Ship) is widely considered "worth it" as it is one of the most iconic experiences in Japan's Fuji-Hakone-Izu National Park. The ships, which are whimsically modeled after 18th-century European warships, offer a 30-minute journey across Lake Ashi with stunning views of Mt. Fuji on clear days. Beyond the novelty of the pirate theme, the cruise provides a practical and scenic connection between the Hakone Ropeway (Togendai) and the historic Hakone Shrine and Checkpoint. It is included in the Hakone Free Pass, making it a cost-effective highlight for most travelers. For an extra ¥740, you can upgrade to the "First Class" cabin, which offers plusher seating and a less crowded deck for photography, though the standard deck is perfectly adequate for enjoying the fresh alpine air and the view of the floating torii gate.
