Resource-Consuming "All-Out War" Needed High-Impact Artworks

These are typical 1900's Russo Japanese Wartime artworks, with some taste of Edo Era's Ukiyoe or Nishiki-e

Japanese Traditional Paint

These are 1930's Second Sino Japanese War National Bonds Advertising Artworks.

Fund Raise Artworks      Modern Art

In the late 1930's, Japan was dragged into the quagmire of the Second Sino-Japanese War, consuming national resources far more than the war against Russia in 1900's.

Art might not have been allowed to have some luxury to be just ART itself & to be away from working hard in order to "convey firmly" something to people.

The government needed their people's more attentions to the war, 

using artworks with some unpredictability and impact to people of that time.
The Center of Japan is not Edo, but Tokyo. The Edo Era was literally gone.

I am not an expert in the art history and unable to speak about it from that perspective.
No wonder a world art trend had changed and that affected Japanese art.

Yet, politics apparently took much role in changing Japanese war art trend, I think.
The above 1930's artworks really are working & acting so hard to convey something important and trying to drive people where they were supposed to go to at that war time.

As for my preference.... I like both Russo Japanese war style & the 1930's ones.
