Convenience store chains in Japan are well known for stocking everything from boxed lunches to dress shirts, often living up to their name by offering myriad services ranging from dry-cleaning and bill payment to parcel pickup.

In a sign product offerings may still have room to grow, Seven-Eleven Japan Co. appeared ready to up the ante after news went viral that it planned to sell draft beer at some stores in Tokyo and its suburbs starting Tuesday.

The chain had not widely announced the service in advance because it was planned to be a pilot project, but social media picked up on it just as beer taps were being installed for the test.
