Ways to buy lots of raw photos

Because I entered the industry late and am not in Japan, I cannot go to Akihabara and other holy places of life photography to look for the life portraits I recommend. Later, I discovered that there were a lot of Japanese rice for sale in Japan’s online second-hand market, or the model I was looking for was an old model, so it was relatively cheaper. I also found other peripherals such as folders/mobile game prizes, which is so powerful!
