When is it? Dates and the two waves

The Morisugi Challenge (“morisugi” means piled too high) is Lawson’s signature promotion: the same price for a much bigger portion. It started in February 2023 and has run 8 times so far. This round is called the Super Happy Challenge (Cho Happy-sugi Challenge) and brings 24 items in two waves: 21 “Morisugi” items with about 50% more, and 3 “Kosugi” (too rich) drinks with about 50% stronger flavor.

Wave 1 goes on sale Mon Nov 16 and Tue Nov 17, wave 2 on Mon Nov 23 (a public holiday) and Tue Nov 24. A few rice bowls, yakisoba and desserts hit the shelves on the Monday.

◆ marks release days. Monday items arrive in the evening in some areas; the roll cake and the Basque cheesecake go out on Monday evening.

Dates: Tue Nov 17 – Mon Nov 30, 2026 (14 days; some items from Mon Nov 16)
Stores: About 14,000 Lawson stores nationwide (as of end of Oct 2026). Lawson Store 100 is not included
What: 21 Morisugi items (about 50% more filling, weight, etc.) + 3 Kosugi drinks (about 50% richer)
Price: Unchanged. Just pick them up and pay at the register as usual
Quantity: Each item has a limited supply and is gone once it sells out

Wave 1 (Nov 16–17): 16 items

The usual favorites are back: onigiri, sandwiches, yakisoba and the roll cake. This time towels and masks also get the Morisugi treatment.

Onigiri, sandwich, yakisoba and desserts

Lawson’s side-by-side photos make the extra portion obvious. The roll cake has the largest supply this round, about 3.77 million.

All images are for illustration. Arrival times vary with each store’s delivery schedule.

How much more? Household items double, snacks get 60%+

Every item says “50% more,” but what grows differs from item to item. With the regular product as 1, here’s how they compare.

Snacks calculated from Lawson’s gram weights; household items from the official size, sheet count and piece count.

Among the food, only items labeled by total weight, like the roll cake, the Basque cheesecake and the takana mentaiko onigiri, become 1.5× as a whole. In the sticky rice bowl it’s the toppings, in the yakisoba and udon the noodles, in the champon the vegetables, in the tuna sandwich the tuna salad and in the crêpe the cream. The pork and egg onigiri gets two slices of pork luncheon meat, 50% or more.

What sells out first? Units per store

The press release lists a supply figure for each item. Divide by roughly 14,000 stores and you get a rough number per store. Actual deliveries vary by store, so treat these as averages.

Red = under 5 per store, yellow = under 30, blue = 30 or more. Karaage-kun is left out because no supply figure was published.

The roll cake (about 269 per store) and the takana mentaiko onigiri (about 175) are plentiful, but the four household items work out to just 2–4 per store. If you want the towels or masks, go on release day, Tue Nov 17.

6 tips to make sure you get them

Get desserts the evening before. The roll cake starts appearing on Mon Nov 16 evening and the Basque cheesecake on Mon Nov 23 evening.
Buy household items on Tue Nov 17. At 2–4 per store on average, release day is your best bet.
Go to a regular Lawson, not Natural Lawson. Natural Lawson doesn’t carry 12 of the items.
Wave 2 starts on the last day of a 3-day weekend. Yakisoba, champon and the Basque cheesecake arrive on Mon Nov 23, the end of the Nov 21–23 long weekend.
Show your points card. At Lawson you can earn points with a Ponta card or a d POINT card. The price is the same, so you earn points as usual.
Post about it and enter the giveaway. Quote-posting your review gives you two shots at QUO Card Pay.

FamilyMart is also running its buy-one-get-one deal until Nov 30; see FamilyMart Buy One Get One Free: Nov 10–30 Item List. If you collect Ponta points, the AirWALLET new-user bonus of 2,000 Ponta points is worth a look too.
