Cultural wartime insensitivities aside, I have had both of these photographs from mid 1900s Japan saved on my desktop for the last 2 weeks.
1. They are fantastic photographs.
2. Check out the Schoolboy blazer on the protesting student. The undone white collar under the jet black (wool?) blazer with the metal buttons and oversize sewn loops. As sharp as you can get without a formal suit neckline. The worker assembling the model ship in the 2nd photo is wearing what appears to be an old-school loom spun cotton henley - similar to the ones Merz B. Schwanen is producing today. The thick hems on the sleeves and the neckerchief = perfection.
