China and Japan have rich histories and cultural traditions that are reflected in their architecture and interior designs. In China, timber was commonly used for construction, along with materials like stone, brick, and silk. Traditional Chinese homes had T-shaped roofs and architectural details that harmonized with nature. Japanese architecture was influenced by China but developed its own distinct style using materials like wood and bamboo. Traditional Japanese homes featured shoji screens, fusuma doors, tatami mat floors, and bathing areas separated from toilets. Both cultures emphasized simplicity, natural elements, and flowing interior spaces.
