history
団 is a Japanese simplified (shinjitai) form of 團. It is not used in standard written Chinese — the equivalent character is 团 (group / round / ball, as in 团结 'unity', 集团 'a conglomerate').
register

囗 the enclosure radical wraps the inside, suggesting things gathered and bounded into one round group. The bottom stroke is written last, after the inner part.
