Can someone, who understands Japanese, confirm this?

Well at the pre launch press briefing the rocket has been confirmed as in the 204 configuration with the 4S payload fairing. That thing on top might be heavier than one would expect....Oh and for the 24th "T-zero is set for zero seven colon four four colon zero zero Zulu".
DSN Corporation is a joint venture between SKY Perfect JSAT Group (JSAT), NEC, NTT Com and Maeda Corporation. It is a private-public inititative where DSN will finance and manage the Japanese X-Band military network.Officially everything was ordered by JSAT, with the first of two satellite ordered to MELCO (on DS2000 platform) and the second to NEC (on the NX-G platform). If I'm allowed to speculate, I think that NEC's place was logically MELCO's. But they had an over-billing scandal to the Japanese government and thus they were forbidden from bidding on government contracts for five years.This would explain why everything was left to JSAT to decide, so they could procure from MELCO. Given that they gave one satellite to each provider, I would also bet that the Japanese military wanted to keep two suppliers of milspec satellites. This enabled NEC to get one contract. I would aso assume that DNS-1 was the "safe" satellite and DSN-2 was the "high risk" bird since NEC has never made such a big GSO bird.Reality was that MELCO screw up DSN-1 delivery (a tarpaulin blocked an exhaust valve con the container and DNS-1 was overpressurized), and thus was delayed at least by a year.So was was originally the backup craft, will be the first to be put into service.

Based on what I've seen from JSAT both sats are MELCO DS2000 busbut with NEC as prime contractor - i.e. MELCO built the sat bus and NEC integrates it.. that may be old info though so I'd be happy to see a more up to date source
It seems that no-one's awake here to help with screenshots so here's the webcast link posted again for your reference:
鹿児島市からはH-IIAのロケット雲が時間帯の割にしっかり見えた。固体ロケット4本の力？ #JAXA #H2AF32
DSN-2 separation!
Boostback and LANDED!
In the respective DSN-1 thread it said NEC was punished by the Japanese MoD for something it did so it lost DSN1 integration contract to MHI's MELCO which will perform the entire integration itself in place of NEC. NEC still retained to DSN2 although NEC will lose out on several future satellites as a part of its punishment.I might have it backwards.
The H-IIA must have one heck of an ability to transform itself into the old H-II used in the 1990s while falling back.
The Transformers, more than meets the eye
