2nd Street is located in Koenji, where some of the best thrift stores live. While there are other locations, I recommend this shop simply because there are so many other thrift stores next to it to explore in case you don’t find anything. This area has a whole street lined with secondhand clothing stores. 2nd Street is the large 2 floored building among them, you won’t miss it. If you dig deep you will find brands like Converse, Supreme, and Champion. Be warned that the men’s shoe section is very expensive compared to what you can find oversees, but still cheaper than a retailers of course. Check out their instagram(@2ndstreet_official) to get a better idea of what styles they carry. Photos found on their website.
