In 1908, Canadian Labour Minister Rodolphe Lemieux negotiated with Japanese Foreign Minister Tadasu Hayashi an agreement limiting Japanese immigration to Canada. In accordance with the gentlemen`s agreement, the Japanese government has agreed to voluntarily limit the number of Japanese immigrants arriving in Canada each year. Japan has agreed to limit the number of passports it has provided to workers and domestic workers to 400 per year. Four classes of immigrants would still be allowed to enter Canada: returning residents and their wives, children and parents; Immigrants employed by Japanese residents in Canada for personal and domestic services; Canadian government-approved workers; and contracted farm labour by Japanese landowners in Canada. Although no specific legislation has been adopted to enforce the quota, the agreement has resulted in a significant reduction in Japanese immigration. In the year following the agreement, only 495 Japanese immigrants arrived in Canada.  A gentleman`s agreement, defined in the early 20th century as “an agreement between gentlemen who looks at price control,” was described by one source as the loosest form of a “pool.”  Such agreements have been declared in all industrial sectors and are numerous in the steel and steel industry.  Gentlemen`s agreements, because they are informal and often not written, do not enjoy the same legal and regulatory protection as a formal contract and are therefore more difficult to implement. Let me begin first for the laborious thoroness and admirable temperament with which you have gone in the case of the treatment of the Japanese on the coast . I had a conversation with the Japanese ambassador before leaving for Panama; read to him what I had to say in my annual message, which he obviously liked very much; and told him that, in my view, the only way to avoid permanent friction between the United States and Japan was to limit as much as possible the movement of citizens from each country to each other to students, travellers, businessmen and others; As no American worker tried to enter Japan, the need was to prevent all immigration of Japanese workers – that is, from the Coolie class – to the United States; that I really hoped that his government would prevent his coolies, all their workers, from coming to either the United States or Hawaii. He was strongly committed to this view and said that he had always opposed Japanese coolies going to America or Hawaii… I hope my message will calm their feelings for the government to tacitly stop all immigration of coolies into our country.
Anyway, I will do my best to achieve it. In the automotive industry, Japanese manufacturers have agreed that no standard vehicle would have more than 276 hp (206 kW; 280 CH); The agreement ended in 2005.  German manufacturers limit the maximum speed of high-performance sedans (berlines) and breaks to 250 km/h.   When the Suzuki Hayabusa motorcycle exceeded 310 km/h in 1999, fears of a European ban or regulatory intervention led Japanese and European manufacturers to limit to 300 km/h at the end of 1999 See list of the fastest series bikes. Gentlemen`s agreements have often been concluded in international trade and international relations, as well as in most industries. Gentlemen`s agreements were particularly prevalent at the birth of the industrial era and well beyond the first half of the 200th year, as regulations often delayed new business practices. It was found that such agreements were used, among other things, to control prices and limit competition in the steel, iron, water and tobacco industries.
