Hi Knightmo
1) Thanks for not proffering a Japan populated solely by ninjas and rikshas!
..possible fuedal era japan people/critters.
-Kappa.
-an unbeatable samurai entity which I forget its name.
Kappa were a sort of goblin with a bird's head and wings. These would make cool figures.
-Kabuki
Kabuki was Japanese theater for the business classes in Tokyo (Edo). These actors would make excellent figures. They are very colorful and flamboyant.
-monks
Yamabushi (the warrior monks who inhabited the mountains around Kyoto and Nara) would make excellent figures. They are customizeable now, but it takes a little work.
I think these guys are mostly pre-feudal, though. They ran amok during the Heian era, and after the [Shogun] Nobunaga came into firm control, monasteries were forbidden to keep armories.
-rice farmers
-gamblers (all tatooed and what not)
By gamblers you mean the mafiosos (yakuza) who ran the gambling rings and prostitution houses. These would make great figures.
-Dragon (and perhaps Tiger, Turtle, and Phoenix)
-Shu(or Fu) dogs
I think Fu dogs are entirely a Chinese image, but not certain. These dogs weren't indigenous to Japan. I think their presence in Japanese art was entirely copied from the Chinese. I haven't seen a whole lot of representation.
But considering I own a Pekingese and a Japanese Chen dogs in real life, I'd love to see these.
Some things you left out:
1) The horse-headed and bull-headed demons of Japanese hell.
2) Heian-era samurai heros like Raiko and Kintaro the Golden Boy.
3) A playset of the Rashomon gate in Kyoto (famous as a place for leaving the dead after the gates fell into ruins during the feudal era).
4) The Gempei wars (pre-feudal, about which the Tale of Heike is centered)
5) Earless Hoichi, who performs storytelling every night for the ghosts of the defeated Taira clan and gets his ears torn off after a monk writes sutras all over his body.
6) Japanese ogres, Oni.
7) Fox spirits (beautiful women with fox tails, or fox-headed women, or normal-looking foxes)
8) Japanese ghosts (pale figures with disheveled hair)
9) Weapons:
9a)The Dotanuki two-handed battle sword
9b) military forks used by urban gendarmes to disarm swordsmen
9c) matchlock muskets for feudal ashigaru footmen
9d) elaborate masked helmets worn by samurai commanders
9e) the naginata, Japanese halberd
10) The Tsuchigumo, giant spider
11) The portable shrines of the Kyoto era that the warrior monks carted around and used as free passes to maraud through the city
But don't get your hopes up, Knightmo.
PM will probably give us Ninja city, with a few rikshas for transportation. Think: ninja disguised as riksha puller.
Maybe if I keep my expectations low enough, I'll still be thrilled when the theme inevitably hits the stores...
