The Imperial Raw Silk Conditioning House 
Office: Kitanako-Dori, Yokohama. Director, Mr. G. Haga. 
This house was established in 1896 and is situated in Honcho but was 
removed to a new building in April, 1926. 
The new building is equipped in the most up-to-date manner and is the 
largest conditioning house in the world. A total of 5,000,000 Yen was ex- 
pended in the construction of this building and annex warehouses. The area 
of the entire floor space of all the buildings covers about ten acres. 
Upon the request of people interested, this house receives raw silk in 
bales and does conditioning work upon the samples. The principal operations 
carried on here are to determine both absolute and conditioning weight and 
the amount of boiling off, to test the re-reeling quality, size, knots, strength 
and elasticity of the raw silk. Added to this, some laboratory work upon the 
chemical properties of raw silk is also carried on. 
This house 1s indispensable to the transaction of business in raw silk with 
its fair tests. 
According to the law of Raw Silk Transaction for conditioning weight, 
passed by the Japanese Diet in 1926, this house becomes more important and 
more practical to raw silk transactions. 
The date of enforcement of this law is decided to start July 1st, 1927, by 
Imperial Ordinance issued August 20th, 1926. Therefore, whole silk transacted 
in Yokohama for export must be brought to this house to be measured and 
its weight conditioned. 
This House has a capacity for conditioning about 4000 bales per day. 
Four large warehouses are established at national expense in the court of 
Imperial Raw Silk Conditioning House. These warehouses were built espe- 
cially for preserving raw silk and are of the most modern type and scientifically 
investigated. 
These warehouses are leased by the Government to the Teikaku-Sansi 
Warehouse Co., Ltd., which was organized by prominent raw silk people. 
The Kobe Municipal Conditioning House 
Office: Sakae-cho, Kobe. Manager, Mr. N. Oki. 
The Kobe Conditioning House was established in Kobe by the Govern- 
ment at the same time the Yokohama Conditioning House was established 
in 1896. However, this House was closed due to the centre of the raw silk 
trade moving to Yokohama, but was re-established in 1923 by municipal 
expense for two reasons. The first because of the remarkable development of 
raw silk industry in Western Japan where this port (Kobe) is situated, and 
the second reason because of the great earthquake disaster which took place 
on Sept. 2nd, 1923 in the Kanto district, destroying the greater part of both 
Tokyo and Yokohama. 
The object and operation of this House are the same as the Yokohama
