He still knew nothing about the building trade, so he began writing to local contractors. One log home builder, DeWitt Construction, responded. After going to work for DeWitt, Kunishige quickly realized he needed to learn about the construction industry from the ground up. He studied carpentry at Western Dakota Tech, then earned a degree in structural engineering at South Dakota School of Mines & Technology. Four years ago, Kunishige became the owner of Handcrafted Log Homes, which had been a division of DeWitt Construction. Handcrafted Log Homes has won multiple awards from the Construction Industry Center and the Black Hills Homebuilders Association.
