A woman browses through kimonos for sale at Boroichi flea market in Tokyo December 15, 2014. In the 16th century, Boroichi was a place for farmers to buy and sell rags, known as boro, for mending clothes and weaving sandals. Now in its 436th year, the original spirit lingers, with about 700 stands hawking fabric, used clothes and piles of rags. Others sell kitchen tools, pottery, seaweed and spices. About 200,000 people flock to the market, which is only open for four mid-winter days a year – two in December and two in January. (Photo by Thomas Peter/Reuters)
