It looks like a “Don’t Drink and Drive” campaign will be held today, 11/6 (Mon), from 3:00 p.m. at Ozeki’s Kanzuan in cooperation with the police.

If you make a purchase of 2,000 yen or more on the day, you’ll apparently receive a masu box branded with Ozeki’s mark. Kids can get stickers too.
Maybe something like this. This one is from (the Ozeki wooden masu with the Japan Sumo Association logo on Amazon)
