Yokohama Raw Silk Exchange
Office: Honcho, Yokohama. Managing Director, Mr. T. Isaka.
At the Yokohama Raw Silk Exchange transactions in raw silk are carried
on extensively, the time limit for transactions in futures is five months. At
the exchange two sessions (two calls for each session) take place every day
except on Sundays and holidays. The standard used at present, is “Yajima
grade”, size 13-15 denier.
Reelers are using this organization to sell their product for forward deliv-
ery at the time when they buy cocoons. Thus they can be sure of a reasonable
profit and be free from anxiety due to fluctuations of the market during the
period between buying cocoons and selling finished products.
