井上 哲也

He is a calm veteran carpenter who works for the Midoriya family. Definitely skilled, he is respected by those around him and serves as the senior apprentice. His wife and daughter live at home while he stays with the Midoriya Group. He returns home to visit them every day. Because of his levelheadedness, competency, and gentle nature, newer apprentices to the Midoriya Group are extremely dependent on him. He is usually the one who calms Tappei's temper by using a carrot-and-the-stick routine. To Chuukichi, he is "Merciful Tetsu-san".
