Staffa - I'm no longer sure about it being Japanese IP range. The 150 range is an "early assign" block of IPs with assignments to all the then major districts (RIPE, ARIN etc).

It is definitely in the Japanese range:

inetnum: 150.26.0.0 - 150.100.255.255
netname: JAPAN150
country: JP
descr: Japan Network Information Center
admin-c: JNIC1-AP
tech-c: JNIC1-AP
status: ALLOCATED PORTABLE
notify: hostmaster@nic.ad.jp
mnt-by: MAINT-JPNIC
changed: hm-changed@apnic.net 20070824
source: APNIC

What makes you think just because it is TrendMicro, that they are not operating out of Japan?
