Small Studio Pottery Pin Tray - Japanese?

Beautiful square pin tray from featuring a leaf motif. It is beautifully made, very Japanese in look and feel with a tenmoku style glaze.  Indeed there is a small mark on the underside of one corner that looks to be a Japanese character but I can't make it out clearly. It is in excellent condition.
