I think my previous comment on another thread topic is worth repeating here:
I was rooting around for Samurai-related diorama stuff and I hit the motherlode with Canon's Hinamatsuri (girl's festival) 3D display here:
https://cp.c-ij.com/en/contents/CNT-0011649/index.html
It has nice 3D figures of the Emperor, Empress and 3 ladies in waiting at roughly 90mm (1/18) scale on the first page.
Also, here's a new link to Canon's Japanese swords and helmets:

Finally a blast from the past, Canon's Costumes of the World:
https://web.archive.org/web/20041204...ume/index.html
Includes 3D-ish figures of a pre-Sengoku era Japanese concubine in a Ju-ni Hitoe, and a woman from Brest, France in the traditional costume. More 1/18 diorama possibilities!
