Where Dotonbori covered street arcade ends, Shinsaibashi starts. Dotonbori and Shinsaibashi is separated by a man-made canal with a road bridge across.
You can planned to cover both these within the same day. Best time to visit the place would be between 10:00am to 8:00pm for shopping and dinning after 8:00pm would be fine.
Our guides told me that this place is the cheapest place for shopping in Japan. I don't know much about this but there are many many shops along the 2 sides of the road. For shopping lover, this is your paradise. You may spent one day along this street.
I had only 2 hours at this place, not enough.
The Shinsaibashi district stretches north-south from Nagahori-dori street to Dotonbori Horikawa, with many long-established shops and department stores. This district is represented by the arcaded Shinsaibashi-suji Shopping Street. Under Nagahori-dori Street, Crysta Nagahori is an underground shopping center of light and water.
Its 'Waterfall Plaza' has a must-see 12 m-high glass ceiling on which water flows. Other attractions include the atmospheric European Street with a stone pavement and retrospective streetlights. American Village attracts many young people with about 3,000 young fashion boutiques and many clothes dealers.
When you go to Osaka, you must go to Shinsaibashi. It's famous for shopping.
