Hamaya was born in a plebeian district of Tokyo, and his early photographs of the 1930s are of its typical denizens: geisha, beggars, prostitutes, and burlesque dancers. Typical urban scenes, in other words. His rejection of this world for the primitive life of peasants in the Snow Country is an interesting example of how important art can emerge from questionable motives....
This was the time when, encouraged by a famous Japanese businessman with ethnographic interests, Hamaya first set off for the Snow Country. The idea was to document the true “Japanese spirit.” Living among the northeastern peasants, recording their dignity in the face of hardship, was for him a “return to Japan.”
I will let you see where it goes from there, but the article and the exhibit both strike me as worthwhile for more than just the stunning photographs included. It is unfortunate that one is so much easier to access than the other.
