I just found a letter in my office which was delivered by Yamato Kuroneko.
It has a "stamp" attached that shows Yamato Kuroneko in katakana.
It was some unsolicited mail by a housing construction company.
Does anybody know how much the company charges for delivery? The letter
would cost 80 or 90 yen via the postal service.
I still need to pay 740 yen when the Takyubin guy picks up anything up to 2
kg...
