Maruyama recalls: "We decided to have students all plant three rice paper plants upon entering junior high school. By the time graduation rolled around three years later, each student would be able to harvest the three plants and use them to make traditional paper by hand. Then they would use their paper to make their own graduation certificates, again by hand. We thought it would be a nice memory for them."
「我們決定讓中富町的中學生一入學就種下三棵三椏樹，等到幾年畢業後，再由孩子自己來修剪當年種植的那三棵樹，然後動手製作自己的『和紙畢業證書』，希望能讓孩子留下一份可貴的記憶，」丸山所長回憶說。
