Hi Andy!
Yes, you are right.

She was once sold in Japan 5 years ago.

DeAGOTINI Japan repeats the almost same series now. This time they say that builders can select three version.
1. Okinawa version (the same as previous one)
2. Battle of Leyte Gulf version
3. Battleship Musashi (not the Yamato)
Additional information will reach me in the near future. I'm going to report here.
Best Regards,
Yutaro
