A follow-on question to William Graham's article:
"Japan initiated the IGS programme following North Korea’s attempted launch of the Kwangmyŏngsŏng-1 satellite in August 1998; a launch which overflew Japan and demonstrated North Korea’s ability to develop a rocket capable of attacking Japan."
Does the Japanese military and intelligence organs have access to American reconnaissance data, then and now?
If so, why did the Japanese government feel it necessary to begin and maintain their own satellite reconnaissance program? Were they not getting all the information that they needed to make informed decisions?
Do the Japanese share their reconnaissance data with American intelligence?
Background: some first-world American allies seem content without their own independent satellite reconnaissance programs--the UK being an example. What's different here?
I understand that there may not be a complete answer available in the unclassified realm, only informed deduction or speculation.
Curious,
Zubenelgenubi

At the CSICE website
http://www.cas.go.jp/jp/gaiyou/jimu/csice.html
there is a document
平成27年度予算概算要求について
that gives future launch plans
It shows Optical 5 with the same launch date as Radar Spare - could they both be on this rocket?
It gives Optical 6 in 2016, Radar 5 in late 2016, Radar 6 in 2017, Optical 7 in 2019,
Optical 8/Radar-7 in 2021, Data Relay Satellite (data chukei eisei) in 2019, Optical Test
Satellite in 2021 following on from a ground test of a large optical sensors to be completed in 2015.
Apologies if this has already been gone through here...
I think this one will be on the next launch out of TNSC - people on site are reporting that rocket transferal across the island will happen tomorrow, which is pointing to launch somewhere around late March, just before JFY 2014 ends.
Yes, I just found an article that says H2A-28 will carry Optical-5.

Thanks for that information JCM. Congratulations to Japan for the successful launch!
Zubenelgenubi, I'm guessing that the US didn't provide that information about North Korea which may have caught the Japanese by surprise. There may have been information sharing going on (which explains why Japan didn't have their own reconnaissance satellites until the IGS series), but after that event, the Japanese decided its best to have their own capability.

Here's a video of the launch from a far-off location.
This is a good video, but suffers from VVS ().
Correct orientation, but needs a bit of zoom.
This one shows SRB separation!
Great sound, but needs zoom (and not looking into the Sun!)

Zubenelgenubi, Israel's excuse for developing their Ofeq reconnaissance satellite series was that the intelligence being supplied by the United States was not considered to be "timely" enough and Israel wanted more than the US was willing to provide.
I think that the Kwangmyongsong 1 launch attempt meant that Japan found itself in a similar situation, so they decided to develop their own reconnaissance platforms.

Try this site, it is a government one:-
http://www.mext.go.jp/b_menu/shingi/gijyutu/gijyutu2/060/index.htmSeems to have details of launches but both F27 and F28 are classified launches?

Thank you, Steven P and Phillip C, for your responses to my question--food for thought.

US has cataloged 3 objects associated with the launch - actual TLEs are classified.
The third object could just be accidental debris (insulation panel, etc) or a cover for the radar, but
note that only 2 objects were cataloged for Radar-3 in 2011 (the payload and the rocket stage).

Update: although no TLEs, the catalog shows orbits as
40381 04A 490 x 511 km x 97.52 deg
40382 04B 480 x 500 km x 97.49 deg
40383 04C 497 x 499 km x 97.53 deg
