Even though there were no reviews, we took a chance with this place because it was cheaper than the other luggage storage places around Hakata Station. We were worried at first because there is no sign for “Bounce” anywhere and the location is actually a Karaoke place called “Big Echo”. We were confused because it was a karaoke, but trusted our bags there and everything worked out smoothly. I’m pretty sure they just stored our luggage inside a karaoke room, but hey. It worked. It was just right outside one of the exits of the station and although the karaoke part was bizarre, drop off and pick up was super easy and smooth and we got our luggage back safe and sound. Reservation online was also very easy and they had very flexible pick up times, which we also appreciated!
