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?

How would you know the interface to winrar fails if you dont go out of your way to install some shitty 3rd party app to provide file compression
