This is a market in every sense of the word. No modernity and only great products such Shinjuku or Tsukiji. They sell everything and everything is very cheap. Jerseys that are fakes, appliances, clothing, backpacks, food, shoes, it is a chaotic environment, and vendors are yelling for you to come to their stall, small food stalls for snacks. A different environment in comparison to the always tidy Japan. Also, if you have lost your suitcase or need to buy some cheap clothes this is the place.
