For Japanese architect Tamotsu Teshima, design is the act of creating a place that enriches people's hearts. Tamotsu Teshima regards architecture as a symbol of culture and craftsmanship. In his opinion, Japanese culture is born from repeated destruction and reconstruction, and respects the relationship between man and nature. Therefore, environment, humanity and sustainability are the core of design.
