The Profitable World of Designing LINE Stamps

LINE creators market

If you use the Japanese messaging app LINE then surely you’re familiar with stamps, or stickers, a series of colorful illustrated icons that are often accompanied by a word or two. Stamps and their popularity have been solely responsible for the explosive growth of LINE to capitalize on this trend the company, in May of this year, launched “Creators Market,” a platform which allows anyone with basic illustration skills to design a set of stamps and sell them each for 100 yen. The artist pockets half of the revenue while the company takes the other half.

one of the most popular series of stamps this year was Wani Kojima‘s “American Pop Kansai-ben” featuring western-lloking characters with saying commonly associated with the comical Kansai dialect.

Since the launch, LINE has raked in an astounding 3.6 billion yen (for simplicity’s sake let’s use 100 yen to the $ and call it $36 million). And that means big bucks for some of the top artists. According to the Nikkei, stamps in the top 10 averaged 36.8 million yen (about $368K) which equates to about $180K in income for the artist. Even artists in the top 1000 made a little over 1 million yen ($10K).

After making roughly 8 million yen ($80K) she quit her job in July and is now a full-time illustrator. She even published a book of essays last month.

Roshihi is also a popular stamp artist who’s “kidokumushi” series features a bug often pestering you for a response.

At a reception in Tokyo last week, LINE recognized some of the top artists and illustrators, noting that the popularity of the stamps is creating a new ecosystem. Popular stamps are branching out into standalone apps, books and merchandise.

  1. Wow! I really enjoy the stamps, but I had no idea that it was such a big business. There’s plenty of “How to” guides to the creators market down at Kinokuniya, maybe I should pick one up, haha.

  2. Thanks for sharing this brill article! I was an instant fan of LINE and introduced it to many friends here in England. I just hope it takes over Whatsapp!
