Tokyo’s cherry blossoms are blooming, the temperatures are creeping back up and that familiar urge to have something cold is starting to kick in again. Just in time, Lotte has brought back one of the more genuinely exciting summer releases in recent years — the alcoholic Coolish Frozen Sour.
First released in 2022, the boozy Coolish caused a stir the moment it hit the market. The concept was simple but brilliant: take one of Japan’s most beloved summer snacks, add a 5% alcohol kick and sell it in the same squeezable pouch that everyone already knows and loves. It was an instant hit, and fans have been waiting for its return ever since.
This year it’s back in the same two flavors that made it popular — Lemon Sour and Grapefruit Sour. Both use real blended fruit flesh and peel, giving them a genuine citrus bite rather than an artificial sweetness.
Japan’s Favorite Portable Dessert
If you’ve somehow avoided falling down the Coolish rabbit hole until now, here’s why everyone else is so obsessed.
Coolish is a squeezable pouch ice cream by Lotte that has been a Japanese summer staple for years. The genius lies in the design: unlike regular ice cream, it’s specifically engineered not to melt in your hand. No racing to finish it before it drips down your arm, no sticky fingers, no need to find a bin for a wrapper. It’s entirely self-contained in its compact pouch, which means you can eat it on the go and at your own pace.
Then there are the convenience store hacks. Social media has spawned a range of Coolish customizations, but the one that really took off involves squeezing a vanilla-flavored pouch into your iced coffee and giving it a stir. The result is a creamy, frothy, Frappuccino-like drink that costs a fraction of what you’d pay at a coffee chain and takes about 15 seconds to make.
The lineup goes well beyond the classic vanilla. Regular flavors include chocolate, melon soda, matcha, lemon and peach — enough variety to keep things interesting no matter your mood. That combination of portability and versatility has kept Coolish at the top of the convenience store freezer game for years.

Where To Buy Coolish Frozen Sour
The catch? Don’t expect to find them on your local convenience store shelves just yet. For now, Coolish Frozen Sours are being rolled out exclusively at stadiums, music festivals, karaoke chains and leisure facilities as well as online retailers — making them very much a summer event staple, perfectly suited for cracking one open in the stands on a sweltering day at a baseball game or during the golden hour at a summer music festival.
