The missionaries who were appointed to Dozaki church undertook welfare work. On Goto, there were many children whose parents could not afford to raise them. Seeing this situation, the French missionary Father Marmand established a children’s home. It was established in a normal house in Oodomari with the help of women from the parish, and was called “kobeya”.

As the number of children increased, it became too cramped and so was moved to a building adjacent to Dozaki church (although it later had to move again more than once owing to church reconstruction work). This institution, called Okuurajikeiin (literally “Okuura institution of charity”), saved the lives of many children and brought them up. It still exists today, and continues to retain its original ideals. It is a place where the Christian teaching on charity is put into practise.
