Welcome to the finest guesthouse / hostel in the funniest city. The 3rd J-Hoppers hostel was opened here in Osaka in January 2008. A former bachelor quarters has been remodeled into a fully-appointed backpackers guesthouse / hostel.
It is a 15 minute walk from Osaka central station and also good for a day trip to Kyoto, Nara and Kobe from Osaka.
