This summer, Shibuya Scramble Square is hosting a hands-on pop-up event: "Don't Drink! Okuchi Parlor" opens for two days only, Saturday, August 15, and Sunday, August 16, 2026, on the 1st floor (Urban Core Space), brought to visitors by Bitatto Japan Co., Ltd.
Built around the theme of "oral care so delicious it might tempt you to drink it," the event reimagines the world of the Okuchi mouthwash series as a "parlor." With playful touches that make passersby pause and wonder, "Wait, are they drinking something? Eating something?", it turns the assumption that oral care has to be bland on its head, offering a fun, cute, and photogenic experience meant to make oral care feel more approachable.
Free to Join: Try the Ice-Cold Mouthwash

Scoop up a spoonful of whipped-cream-like foam and pop it in your mouth. The refreshing sensation that spreads through your mouth is a new kind of oral care experience unlike anything before.
Because it's a foam, there's no need to rinse with water — just wipe it away with a tissue for quick, easy oral care, even in places without a sink. It's a new style of oral care suited for outings, the office, outdoor activities, travel, and even as an emergency stockpile item.
Brand Character "Lemon-chan" Also Appears
*Lemon-chan's appearances are irregular and not guaranteed.
The Okuchi series' brand character, Lemon-chan, will be at the venue to greet visitors. Photo opportunities and interactions with Lemon-chan add to the "Okuchi Parlor" experience.

About the Okuchi Series
The Okuchi series debuted in August 2018 with Okuchi Lemon, a stick-type mouthwash that stood out at the time for letting users see the grime it removed after rinsing. That unique visual experience, paired with a fruity taste, built a loyal following, and the series has since grown into a mouthwash line that draws attention both in Japan and overseas, with buzz on social media. Beyond mouthwash, the lineup includes breath mints, toothbrushes, and other products designed to make everyday oral care more enjoyable.
