What Is “Lawson Day”?
If you’re a die-hard fan of Japanese convenience stores, or just a traveler with a trip to Japan in the works, this one’s for you. Every year Lawson convenience stores celebrate June 3rd as “Lawson Day” (ローソンの日), an anniversary officially recognized by the Japan Anniversary Association as of this year. It marks the date when Lawson opened its very first store in Japan, the Sakurazaka branch, which signaled the arrival of Lawson in Japan from the surprisingly suburban neighborhood of Toyonaka, Osaka back in 1975.
Why June 3rd?
It’s no coincidence that Japan’s very first Lawson opened its doors on June 3rd – it was an intentional marketing choice, decided by Japan’s love of number puns. While it’s a little bit of a stretch, the numbers 6 and 3 can be read as “Ro” (ろー) and “Son” (そん) in Japanese, which phonetically combine into “Roson” – the Japanese pronunciation of Lawson! Because of this fun little pun, the combination of 6 and 3 has even become something of a lucky number combo for many Lawson staff.

The Morisugi Challenge: Going Overboard (in a Good Way)
Lawson’s Morisugi Challenge (盛りすぎチャレンジ), which might be roughly translated as the “over-the-top” or “overflowing” challenge, is a popular promotion for the convenience store, and it’s back and bigger than ever to celebrate this major anniversary. For a limited time, popular products are being upsized without any additional cost! Customers can hunt for these special deals at Lawson stores around Japan from June 3rd through Monday, June 30th.

Of course, since this is to celebrate their 50th anniversary, Lawson is apparently preparing to go all out. The convenience store is rolling out a record 41 different upsized products, which makes it the most wide-ranging Morisugi Challenge line-up to date! They’re planning staggered release dates, so you’ll have to keep visiting Lawson throughout the month to catch all the “morisugi” products.
Looking Forward With a Look Back: Examples of Previous Upsized Lawson Products

While Lawson has never gone so far with their Morisugi Challenge promotions before, this isn’t the first time they’ve turned up the volume on some of their best-sellers. To get an idea of what to look forward to in June 2025, here are some of the products from their last Morisugi Challenge back in February.
・Napolitan Spaghetti: more noodles and lots more sauce
・Premium Roll Cake: generous cream filling
・Chashu Mayo Rice Ball: stuffed with extra pork and mayo
・Grilled Pork Bento: upgraded to fill their larger bento box
・Teriyaki Chicken & Egg Sandwich: stuffed to the brim
・Fluffy Cheesecake: more creamy cheese filling
・Rich Pork Ramen: more noodles and more toppings
As is the case with most promotional schemes, these upsized products are available for a limited time and only in limited quantities, so once they’re gone, they’re gone! You’ll also want to keep in mind that not every item will be available at every Lawson store – Okinawa branches are sadly only getting 40 of the 41 products in the first place. To find out the specifics of what and when to look for, you can check the Lawson 50th Anniversary website and Lawson’s official social media.
Visiting Japan in June? Don’t Miss This Convenience Store Celebration

Lawson Day isn’t just a celebration for the brand, it’s a celebration for convenience store lovers too. With supersized portions and the same convenience store value, customers can indulge just a little without breaking the bank. If you’re planning to be in Japan during June 2025, you’ll probably want to add a Lawson run (or two) to your itinerary.
