Konnichiwa Don-san. Douitashima-shi-te!
It's correct that Don-san has said.
zishinyochi = earthquake erediction. It's correct.
zishinmimi = earthquake ear (hearing a sound before earthquake). It's correct,too.
But Japanese called "zishinmimi" does not exist.
"zishinmimi" is the coined word which I made.

The bulletin board was prepared in my ENGLISH website.
