But the picture is of a tanker.

Asahi Maru No.10
It is a Trawler (FV)
IMO No: 7640017
??????????

Google sort of translates that to "Tenth Asahi Maru", the natural assumption being "Asahi Maru No. 10" - the problem is there doesn't seem to be one. Every other number, but not number 10 !

Here's her name written in kanji:

第十朝朋丸

Now, there are other photos of this small tanker online, but let's see if our Japanese speaking members can help.

Cheers
