Tombori River Cruise is a mini cruise along Dotombori that lasts 20 minutes. It has a regular fee of 900 yen, but it is free with the Osaka Amazing Pass. It is quite difficult to enjoy the view since railing is quite high and there are a lot of passengers (there are quite a lot of seats available and they tend to be fully packed). The emcee I had was bubbly but mostly spoke in Japanese and her commentary mainly involved waving to all the passers-by. Overall I neither enjoyed the view nor gleaned information of Dotombori. Assuming you have the Osaka Amazing Pass, you might want to take this ride if you are in the area, have spare time, and want to rest your feet, but it is definitely not a must do, and in fact is not really something I would be willing to pay for without the Osaka Amazing Pass.. Do consider the Pirates of Osaka ride for a more enjoyable experience, which is similarly a mini cruise along Dotombori that lasts 20 minutes and is free with the Osaka Amazing Pass, but has fewer passengers, lower railings, and multilingual staff.
