I found Namihei Koshige's Blog and he has interesting pictures from the Power Rangers RPM set. He is a suit actor and has been since 1995, he has done most of the female rangers.
These are from November and December, it seems one of the Rangers is gonna be in a wedding dress. And here is a delightful post on how he has doubled for the Rangers in non-suit like Max (Wild Force), Cassie (Space), Syd (SPD), Trip (Time Force), and Ethan (Dino Thunder).
Here is an interesting post from Namihei Koshige, the suit actor for most of the female Power Rangers for the past 15 years. This picture includes him (in middle), Adelaide Kane (Tenaya 7) and some of the crew, I do not know who exactly. The post is about the wrap-up party for Power Rangers.
This is picture has Koichi Sakamoto, stunt director and producer of Power Rangers receiving a card and flowers at the wrap-up party for Power Rangers RPM. This was posted March 30, 2009, Namihei reflects on his 14 years being on the show since 1995. I can not translate it, but I got most of this from a google translator, which isn't 100%.
Here is his YouTube channel, which has only videos of him and two on the set, but not in Power Rangers outfits so we will not know what it is from until we see the episode. The above picture is a Jungle Fury set. He does great work and I am an admirer of his work.
Shipping of Ranger and monster costumes and props usually happens in March and April from Japan to overseas and it has not happened as of yet an insider says.
