Osaka Castle Aqua Bus Boarding Deck

See Osaka from the water by hopping on a boat tour. Two vessels depart from the boarding deck at Osaka Castle: the Aqua Liner cruises along the central Okawa river for around 40 minutes, while the Aqua Mini connects the castle park with bustling Dotonbori. The Aqua Liner is the larger of the two, has a transparent glass roof and is equipped with air conditioning and toilets, so you can look forward to a comfy ride whatever the weather.
