It’s always worth remembering that a huge slice of Japanese art and imagery (of any variety from all periods) has been borrowed from or loosely based on earlier Chinese art/history. That includes religious figures, legends, general art styles and subjects etc
That can be very confusing at times but the usual giveaway is the unique aesthetic that the Japanese bring to art. It is different to Chinese but takes a while to recognise. Also the Japanese pay meticulous attention to detail.
A good example is to compare Japanese netsuke with the modern Chinese stuff. Same applies with tsuba. Even very well carved Chinese pieces are artistically totally different.
it is difficult toexplain but Japanese often has a “softness” to it.
