Kutani-yaki Matcha bowl with gold-painted camellia design by Kazan (or Kafu) - Tea Ceremony Utensil This item was carefully kept by my mother, who loved the tea ceremony. It was purchased over 30 years ago. Due to long-term storage, the paulownia wood box has aged and shows some staining. Please understand this. I am an amateur and do not know the details, so please refrain from asking questions.
