Many Japanese homes have beautifully decorated altars called "butsudan" where families pray to Buddha and their ancestors. Their construction involves several traditional crafts. But with changes in Japanese lifestyles, they're now less common.

Working with his family, he's found a new way to use his skills and preserve a piece of this Japanese tradition.
