I'd forgotten that I posted my Gamera poster here, so here's a very belated "Thank you!" to everyone who commented on it.
And here's a collage I made of all of Koichi Ueda's appearances in the Godzilla series.
I couldn't find him in G2K, but August Ragone told me Ueda plays the Tokai power plant director. I checked both the Japanese and US versions and I still couldn't see him, though that's definitely him on the phone with Katagiri (in the Japanese version, anyway). That's why he's not actually
in the picture for G2K!
