Why did japan join world war 2?A paragraph if can

World War II really began when the Japanese army seized Manchuria in 1931. But that was not the starting point of Japanese aggression. Japan started in business as a land-grabbing power in a small way. Moving cautiously, while its modern navy and army were still in the infant stage, Japan took over several groups of small islands not far from its homeland without having to fight for them.

By 1894 it was strong enough to challenge the weak and aging Chinese Empire. In July of that year Japanese naval guns fired on Chinese ships without warning. For the next fifty years Japan’s conquest and absorption of Asia and the Pacific islands has continued, step by step, with time out to consolidate the gains and gather strength for the next move.

The successful war with China in 1894–95 added Formosa and the nearby Pescadores islands to the Japanese Empire. After defeating Russia in 1904–05, Japan took the south half of Sakhalin and the southern tip of Manchuria known as the LiaotungPeninsula. In 1910 Korea was annexed. At the end of World War I, the victorious powers handed the Japanese a mandate over the former German islands north of the equator, one of the most important strategic areas in the Pacific. Twelve years later the Japanese began carving out sections of China, starting with Manchuria in 1931. On the eve of the present war, Japan seized control of Indo-China from defenseless France and reduced Thailand (Siam) to the status of a puppet.
