In addition to the Japan Night Walk Tour, another great way to see the famous signs of Osaka is the Tombori River Cruise!
This cruise goes right down Osaka’s Dotonbori River and straight into the Dotonbori shopping district itself. You will get to see Dotonbori’s famous signs up close as the boats cruise right pass the “Glico Man” sign, the Asahi and Chintai beer signs, and various other mechanical signs, illuminated signs, billboards, video screens, and paper lanterns.
If your big dream is to see these signs up close, this is one great way to make that dream come true!
