Can we have as much background detail as possible to this please including how these people found you and whether you are selling shares.
What exactly is this recertification deposit they are asking for?
I cannot find any reference whatsoever on the Internet to this company. That is not to say that it does not exist. Certainly, the Foreign Securities Commission exists in Japan with those telephone numbers, (unless that is a very elaborate scam).
Scammers are now producing very good quality letterheads to try to entice people into paying money. What does seem odd is that the seller is being asked to pay $7000 as some kind of security for a purchase.
What is the background behind how and why these people were introduced to you want to buy some shares?
