Jankara is a karaoke venue in the center of the shopping street near Namba Station in Osaka, where you can sing along with ramen and drinks. Ramen and free drinks are available, and bringing in outside food is allowed at all locations. Enter your area, branch, start time, duration, and machine type in the app, and the room number arrives 30 minutes before; check-in and payment are handled at an unmanned machine. Soundproofing is weak, so singing from the hallway and neighboring rooms can be heard clearly.
