Gentlemen`s agreements have come to regulate international activities as the coordination of monetary or trade policies.  According to Edmund Osmasczyk in the United Nations Encyclopedia and International Agreements, it is also defined as “an international term for an oral and unwritten but fully valid agreement.”  This type of agreement may allow a nation to circumvent national legal requirements to enter into a formal contract or it may be useful for a government to want to enter into a secret agreement that does not engage the next government.  According to another author, all international agreements are gentlemen`s agreements because, just before the war, they are all unenforceable.  Osmaczyk noted that there was a difference between gentlemen`s open agreements and secret diplomatic agreements.  In the United States, in 1890, the prohibition of gentlemen`s agreements was introduced in interstate trade relations because the secrecy of these agreements was beyond anyone`s control.  Although the agreement limited the number of adult men who could enter Canada, it did not provide for any restrictions on the wives of Japanese immigrants. After the introduction of the quota, a large number of Japanese women began to migrate to Canada as “image brides.” Japanese men in Canada would choose brides based on photos sent by relatives to Japan. After registering her marriage in Japan, the bride was granted a passport to Canada. The arrival of more Japanese women facilitated a natural increase in Canada`s Japanese population.  In English contract law, an agreement, in order to be binding, must be aimed at establishing legal relations; but in commercial transactions (i.e. agreements that do not exist between family members or friends), there is a legal presumption of “intent to establish legal relations”. In the 1925 case of Rose and Frank Co.
v. JR Crompton – Bros Ltd., however, the House of Lords found that the phrase ” “This regulation is not … a formal or legal agreement … is only a record of the parties` intention “was sufficient to rebut this presumption.  Gentlemen`s agreements between industry and the U.S. government were common in the 1800s and early 1900s. The Bureau of Corporations, a predecessor of the Federal Trade Commission, was established in 1903 to investigate monopolistic practices. Concessions were agreed in a note that, a year later, consisted of six points.
The agreement was followed by the admission of Japanese students to public schools. The adoption of the 1907 agreement spurred the arrival of “image marriages,” women who were closed remotely by photos.  The creation of distant marital ties allowed women who wanted to emigrate to the United States to obtain a passport, and Japanese workers in America were able to earn a partner of their own nationality.  As a result of this provision, which helped to reduce the gender gap in the Community, from a ratio of 7 men per woman in 1910 to less than 2 to 1 in 1920, japan`s population continued to grow despite the immigration restrictions imposed by the agreement.
