I heard from Alex that Wes will be DJ'ing at Cafe Barbes tonight. I'm not sure who else will be joining him, but when we started doing regular gigs there together about a year-and-a-half ago, we were often joined by lounge DJs like Jules, Hitomi Nova and Satoshi.
Cafe Barbes is a popular hangout for some of Osaka's hippest artists, DJs, filmmakers, musicians, photographers, etc.
