Chaji is a form of tea party that individuals perform for a small number of designated guests, and the host decorates the tea room with flowers and a hanging scroll, and entertains the guest with charcoal temae, kaiseki (meal served in the tea ceremony), and koicha (thick tea) or usucha.
茶事とは少人数のあらかじめ決められた客を対象にして個人が行う茶会であり、亭主は茶室を花や掛物で飾り、炭手前、懐石、濃茶および薄茶の点前により客をもてなす。
