This is Shinsaibashi. Here you will find all the big department stores and luxury boutiques, the broad coulourful avenues with Osaka's favourite Kingko trees, the hidden alleyways with their bars and restaurants, and people all the time.
A small magnetic cache can be found here. The GPS might not be completely accurate, but there is a 3D map nearby here. The cache can be found near the crossroads. Muggles galore are also to be seen here all day and all night, so please be stealthy.
