From the opening of its borders to the beginning of the 20th century, silk was Japan's most sought after export and nearly all of it went through Yokohama. The museum, which pays tribute to this period, houses an extensive collection of silk fabrics and an informative exhibit on the silk-making process. People on staff are very happy to answer questions. In the same building, on the first floor, are the main offices of the Yokohama International Tourist Association and the Kanagawa Prefectural Tourist Association. The museum is at the northwestern end of the Yamashita Park promenade, on the second floor of the Silk Center Building.
