A scan from Japan

[centipede <centiped () netvision net il>]

Hi.
I've just been scanned from a server.fseweb.com, IP 211.123.77.226,
a host which belongs to the so-called "FSE-SYSTEM",
which is located in Japan.
It seems that the intruder looked for some ftp vulnerability,
and when blocked by ipchains he crafted some SYN FIN packets to do the job,
and then caught by snort. The whole process was too fast not to be a 
script.
There's no abuse or any other email address one can turn to on that company
but I sent a note to the Japan Network Information System, an ISP which 
owns
that IP apparently. Anyone else received this pattern of scanning,
or anything else from that IP ?
(FSE-SYSTEM reside on IP 211.123.77.224 through .239).
Here are the logs:
