Rough shape. They look original
Would WWII era Japanese boots have 'Japan' written on them in English?
"Knowledge rests not upon truth alone, but upon error also."
They are army officer's boots, the laces are perhaps later war period. There's an near identical pair in Nakata's book. Not easy to find in this style.
Labels with English on them are sometimes seen on officer's apparel as it was all Taylor made.
