Medieval art in Japan speaks of Concubinage,War,Geisha, revolving around the kamakura to the muromachi period ,whilst Medieval European art Speaks of christianity,King Arthur,The 1800's , white nationalism,War,Golden ages,Dark ages. The differences are very obvious there is no king Arthur in
japan and neither was there christianity ,christianity did not reach japan till
1549,but was banned for some 250 years during the Edo period (1603–1868).
and same for Europe ,Europe did not have samurais ,they did not have geishas , Europe never had Concubines (women that bear children for the king , but are not of the marital status.) so you wanted the differences ,you got the differences . bye for now!
