Why is .lzh format still popular with japs?

The rest of the world uses .zip and .rar and these retards still seem to use .lzh a lot.

It's not because the format itself was constructed by a "fellow" Jap is it?

what's wrong with tar, particularly compared to zip? and why would rar or 7z be any more convient than zip? (as far as I can tell, using anything other than zip is a major PITA on windows and linux; and I've been using computers since 94 - zip has always been more convient).
