Two Bonsai enthusiasts have launched an emotional plea to thieves who stole seven trees from them, offering care instructions for their “children”.
Seiji Iimura and his wife Fuyumi said the prized miniature trees were taken from their garden in Saitama, Tokyo.
“There are no words to describe how we feel,” Mr Iimura wrote. “They were precious [to us].”
The tiny trees are believed to be worth over 13m yen ($118,000, £91,750), CNN reported.
Stemming from East Asia and often associated with Japan, Bonsai is a delicate art-form based on specialist cultivation techniques.
The miniature plants are grown in containers that mimic the shape of fully-sized trees, and require expert care.
