The group left the port of Genoa on December 29, 1925,
and arrived at Moji Port on February 8, 1926. They immediately proceeded to Nagasaki to greet the bishop, and arrived at their destination, Miyazaki, on the 17th.
After spending a year there studying the difficult Japanese language and getting used to their new life, Father Cimatti took over the three churches of Miyazaki, Oita, and Nakatsu that had been given to him by the Paris Mission,
and became the parish priest of the Miyazaki Church in February 1927.
In 1928, Miyazaki and Oita prefectures were recognized as independent missionary districts,
and in 1935 they became pastoral districts. Father Cimatti was in charge of the parish priesthood, and under his guidance,
new churches were established one after another in Tano, Takanabe, Miyakonojo, Beppu, Nobeoka, and other places, and the number of believers increased year by year.
In 1930, nine young seminarians and six Salesian Sisters came to Japan. The number of workers increased,
but they needed places to train the seminarians and personnel, but Japan also fell into a deep recession due to the Great Depression of 1929.
Father Cimatti's efforts to support the work were indescribable. He even sent a telegram to the headquarters in Italy saying, "There is no bread."
Fr. Cimatti was convinced that Japan needed Japanese people to lead the country to God. Therefore, he thought it was urgent to train Japanese priests.
To that end, he founded a minor seminary in Miyazaki (which became Hyuga Gakuin after the war) in 1933, and in 1933 he moved to Tokyo and took over the Mikawashima Church,
and in 1935 he founded a novitiate and seminary in Nerima, Tokyo.
In the same place, the Salesian Society also opened its own educational institution, the Ikuei Polytechnic School (later the Ikuei College of Technology),
and established the headquarters of the publishing business of Don Bosco Publishing Company here.
In the same year, 1933, he also established a "relief home" in Miyazaki for abandoned elderly people and orphans,
and in order to maintain and develop this work, in 1937 he instructed Father Cavoli,
also a Salesian, to establish a congregation of Japanese nuns, 「the Miyazaki Caritas Sisters」(now the Caritas Sisters of Jesus).
