I have been a work mainly at industry of broadcasting systems and photovoltaic generation systems. I worked for an architectural design firm in Kawasaki for thirteen years and then for seven years at Fukuda Inc., a middle size general contractor, here in Tokyo. At these two companies, I designed and supervision the construction of various architectural projects including apartment complexes, houses, medical clinics, factories, and hotels in Tokyo and the greater Kanto region. I truly enjoyed the challenge and excitement of designing structures from the ground up.
