Dotombori is one of the three spots most symbolic of and well-known in Osaka–possibly the most famous of them. It is order in chaos, a maddening mix of people and lights and sounds that will assault your senses. Lonely Planet went as far as comparing it to the futuristic cityscape of Blade Runner.* But in my opinion, Dotombori has no comparison, because it is simply the City of Osaka unapologetically being its over-the-top self.
The name comes from the Dotombori River, a canal that runs east to west through the middle of the Dotombori district. A theatre district starting in the 17th century, Dotombori is primarily a nighttime entertainment district today, so there are numerous bars, izakaya, restaurants, food stalls, and entertainments facilities (karaoke, bowling, pool, etc). The city has recently been doing construction work to boost tourism in the area, focusing on beautifying the canal-side boardwalks. Namba’s “love hotel” district can be found on the west end of Dotombori (near Yotsubashi-suji), if that’s what you’re looking for.
Famous landmarks include the giant crab with moving pincers (there are actually three, but the center-most one is the most popular) and the surrounding lights and buildings, the night view of the Glico “running man” billboard, Ebisubashi Bridge (informally known as Hikkakebashi, meaning “pick-up bridge,” as it is a popular spot for hosts who attempt to pick up girls passing by), and the Ferris wheel attached to the side of the Don Kihote shop. There is a Starbucks at the most crowded point in Dotombori, which offers a great view if you like people-watching or just want to take a breather. There are boat tours that go along Dotombori River and connect to other parts of Osaka, as well. And finally, don’t forget to stop at Kinryu, the famous ramen shop that has multiple shops in the district, followed by some cheap and delicious okonomiyaki and takoyaki (fried dumplings with octopus in the middle) from the outdoor food stalls near the river—both of these are Osaka specialties.
The best way to reach the center of Dotombori is from Namba Station (Sennichimae and Midosuji Subway Lines, Kintetsu Lines, Hanshin Namba Line, Nankai Lines), but you can also get to the west part of Dotombori from Namba Station on the Yotsubashi Subway Line, and to the east part from Nipponbashi Station (Sennichimae and Sakaisuji Subway Lines). Dotombori is a 3-5 min. walk from Namba Station on the Midosuji and Sennichimae Subway Lines.
