What is long long man?

"Long Long Man" is a Japanese commercial series created for the Sakeru Gummy candy brand. The series consists of a series of short commercials that tell the story of a love triangle involving three characters: a woman, a short man, and a long man.

The commercials follow the humorous and whimsical attempts of the short man to win the affections of the woman, who is infatuated with the long man. The long man's extremely long and stretchy appearance is a nod to the candy's tagline, "Sakeru," which translates to "to stretch."

The commercial series became popular in Japan and gained international attention for its quirky humor, catchy jingle, and unique storytelling style. It has since spawned a variety of merchandise and even inspired fan-made animations and parodies.
