This route offers a serene and charming voyage to enjoy fireworks at the start of summer. Guests can relax in their favorite places on board and enjoy the spectacle of fireworks bursting across the night sky above the enchanting silhouettes of islands on the sea after sunset. A unique highlight of this route is an up-close view of kaidenma boat races, during a local festival that passes down the tradition of the fast rowboats used by pirates in these waters centuries ago.
