H-IIB launched manned spacecraft

Saw that, there was no thread for this topic. So, I am shamelessly lifting pics and info posted on flightglobal by Rob Coppinger and novosti-kosmonavtiki by the user 'frigate'  ;D ;D

Fig. 10. 10. Shows differences in Soyuz, Apollo, and JAXA's concept for module configuration. Shows differences in Soyuz, Apollo, and JAXA's concept for module configuration. Soyuz is simple for Soyuz type is simple for operation but it is not selected in this paper mainly because of the weight penalty for Launch Escape System (LES has to
kick Habitant Module for Re-entry Module separation). Also, Apollo type is better to enhance functions in Habitant Module such as longer on-orbit staying time capability. such as longer on-orbit staying time capability. Two points major difference between Apollo and JAXA's concept in this paper are as follows.

I wonder if they have decided that they must do it all themselves?

They could take the Chinese approach and license the tech from someone else.  I wonder how much SpaceX or Boeing might charge to fix them up with all they'd need to build a modified Dragon or CST-100?  It might come out cheaper and faster in the long run.

Just getting it through ITAR would probably be more work than designing their own vehicle from scratch ;)

Oh dear, I'd forgotten about ITAR.  Or rather, I hadn't considered that Japan would be on the list of places we couldn't do that kind of transfer with.  I thought we were best buds.   ::)

ITAR doesn't make those kinds of distinctions, even with Canada and the UK. One more reason it needs to be reformed, badly.

Does Japan even need its own manned spacecraft at this point?  Wouldn't it just be cheaper to ride with the Russians or perhaps commercial?

It may be political.  China has their own manned launch capability so maybe Japan feels they should show that they can do it as well.

Plus with American manned launches stopping for a while JAXA might have decided not to depend on the U.S.A. for access to the station.

Ah, yes, I forgot that there is a degree of rivalry between Japan and China.  I wonder if there is still hard feelings over WWII.  Probably so, but that's discussion for another topic.

Anyway, it would certainly be neat to have an Asian space race.  :)

There will be one someday based on documentaries that have been on tv. China being the focal point on what everyone is worrying over.

Hmm, for a name on the new manned vehicle, what about something showing amazement? All other country's manned spacecraft had names like that that made people feel awe over it.
