Once a month, Yoyogi Park transforms into a thriving treasure trove for bargain hunters. With everything from kimonos to vintage toys and hand carved furniture, this flea market is a staple in central Tokyo for both travelers and locals. Located alongside the NHK Studio Park, you can pop by for the one o'lclock live studio taping after you are done at the market. The dates are unfortunately quite irregular, so make sure to check their facebook page for schedule info.
