I saw a big brown bear brand in Korea. Does anyone know what brand it is?

This is Brown Bear. From "LINE?TOWN".

Brown Bear is a simple, silent and expressionless bear. But it's scary and rough when angry. Emotional expressions are dialog boxes (with exclamation points, musical notes, etc.). Secretly like Coni Rabbit. My favorite thing to eat is salmon!

Brown Bear and Connie Rabbit are still popular emoticons, and the emoticons come from Line, a popular application in Japan and South Korea.

Extended information:

"Line Town" is an animation named "Line Town". It began to be broadcast on TV Tokyo on April 3, 2013 and ended on March 2014. It will end on September 26th, with 50 episodes in total. Different from the previous instant noodles broadcast in January, it was completed by a new supervision and production company, but the characters have not changed.

The audience of Instant Noodles is adults, while "Line Town" is mainly for children, and the voice actors are still the same cast. The work tells the story of a small town.

LINE is an instant messaging software launched by NHN Japan, a Japanese subsidiary of the Korean Internet group NHN. Although it is a late-starting communication application and was only officially launched on the market in June 2011, it has more than 400 million registered users worldwide.

The most attractive thing about LINE to users is the “chat emoticon stickers”. More than 250 kinds of emoticons give users an interesting tool to convey their mood when using Line.

Among them, LINE’s official designs of cute and distinctive Mantou Man, Coni Rabbit, Brown Bear and James have been well received, and these four cartoon characters have become important elements connecting other LINE products.
