May be. I'm trying to serch the written status but nothing.
Logically, 202 version with the 4S fairing.

No specific details were released on this latest IGS satellite, known  only as Optical-4, although unconfirmed reports claim it was  successfully separated after its ride uphill on the H-2A.
The JAXA release (http://www.jaxa.jp/press/2011/09/20110923_h2af19_j.html) confirms separation of the IGS satellite.

A third optical satellite – IGS 4A – and a second radar satellite – IGS  4B – were then launched on 24 February 2007. IGS 4A is classed as a  advanced and experimental optical satellite, based on the Synthetic  Aperture Radar (SAR) technology.
AFAIU, a SAR antenna is used on Radar satellites not on optical satellites, which typically use telescopes.

Also, according to the Japanese Wikipedia page on IGS  (http://ja.wikipedia.org/wiki/%E6%83%85%E5%A0%B1%E5%8F%8E%E9%9B%86%E8%A1%9B%E6%98%9F)(different from the English version (http://en.wikipedia.org/wiki/Information_Gathering_Satellite) ;D !):
IGS-4A was "Radar-2" not an optical satellite while IGS-4B was Optical-3-Demo, not a radar satellite.
IGS-5A launched on Nov 28, 2009 was Optical-3.
AFAIU, the "Optical-4" launched this morning would correspond to "IGS-6A"

Yomiuri online quotes "about 60 cm" for the maximum resolution of "Optical-4", the same as Optical-3.
According to the article a radar satellite is scheduled to be launched this year, and another one next year

Object B (which could be the H-2A second stage) is in the following orbit:
