On 18 February 1932 Manchukuo was proclaimed by the Northeast Supreme Administrative Council, nominally in control of Manchuria, and was officially founded on 1 March. It was recognized by Japan on 15 September 1932 through the Japan–Manchukuo Protocol, after the assassination of Japanese Prime Minister Inukai Tsuyoshi.
English translation.
Japan recognizes the establishment of a free and independent Manchoukuo in accordance with the free will of its inhabitants. Manchukuo has declared its intention of abiding by all international agreements pledged by the Republic of China. The government of Japan and the government of Manchukuo have established a perpetual friendly and neighborly relationship, mutually guaranteeing each other's sovereignty. For the peace of East Asia:

2. Japan and Manchukuo pledge to cooperate in the maintenance of mutual peaceful existence by banding against common outside threats. The Japanese military forces are to be stationed in Manchukuo to this end.
This protocol is to be effective immediately upon signing.
