K-ON! has held three collaboration events with the nationwide convenience store chain Lawson in the past, selling original merchandise and distributing limited edition goods.

In addition, original pedometers featuring designs of Hirasawa Yui and other characters were sold on a made-to-order basis, and there was also a great campaign where you could receive an original clear file with the purchase of designated products.
In addition, a "K-ON!" lottery was sold exclusively at Lawson, and many fans frequented their local Lawson.

To celebrate the 25th anniversary of Lawson's popular product "Karaage-kun," a collaboration with "K-ON!" In collaboration with "K-ON!", they prepared five flavors that best fit the image of After School Tea Time and held a vote. The flavor with the most votes would be sold as a limited-time product.
The proposed flavors were "Curry," "Barbecue," "Yuzu Pepper," "Black Pepper," and "Consommé."
The "Curry" flavor was ultimately selected by vote, and "Karaage-kun Curry Flavor" was sold at Lawson convenience stores nationwide as a limited-time product.
Collaborations with Restaurants and Drinks!
As "K-ON!" has grown in popularity, it has collaborated not only with companies but also with products, driving many fans wild.

Asahi Soft Drinks' "Jurokucha" and "K-ON!" collaboration campaign included a character strap with every product purchase.
There were five types of straps available: Hirasawa Yui, Akiyama Mio, Tainaka Ritsu, Kotobuki Tsumugi, and Nakano Azusa, and they were designed so that the character inside could be seen, but in some stores, the Jurokuchas disappeared from the shelves as soon as they were put on display.
The character straps feature a deformed, two-headed design of each character, and it's still fresh in our memory that many fans collected all of them and attached them to their bags.
The campaign was held at many convenience stores, including Lawson and 7-Eleven, so it's likely that most "K-ON!" fans were able to get their hands on some limited edition merchandise.
Denny's

The family restaurant "Denny's" has collaborated with "K-ON!" to offer a collaborative dessert using seasonal fruits.
Specifically, the menu included a "Peach Mille-feuille Pie" and a "Fresh Peach and Milk Pudding Soup," which was surely a must-try for peach lovers.
These items were prominently displayed not only on each table in the store, but also on promotional posters in front of the entrance, so fans who happened to be passing by were sure to stop by without even thinking about it.
Tokai Pickles

Tokai Pickles, known for their "Kyu-chan Cucumber" snacks, has collaborated with "K-ON!" to sell pickled radishes.
The reason why pickled radish was sold as a collaboration product was because "K-ON!" features a joke about Tsumugi Kotobuki's eyebrows resembling pickled radishes, leading to the product being sold under the product name "Mugi-chan's Eyebrow Pickled Radish."
It was a shocking collaboration, but the collaboration product has been sold in supermarkets nationwide, and its special packaging makes it even more visually impactful.
Yui Hirasawa and Ritsu Tainaka, even in their dreams, tasted Tsumugi Kotobuki's eyebrows and exclaimed, "Delicious!" But what's the reality?
Some people may have been intimidated by "Mugi-chan's eyebrows..." and couldn't bring themselves to eat them.
Collaboration with a Railway Company!
