This Japanese Square Pottery Tea Pot was surely not made for export...it has a Mingei, or folk art look. The body is covered with dark brown globules of glaze. There are 4 small bun feet. It is not marked.
Both teapot and cover are in excellent condition: no chips no cracks, no repairs. It is large: about 7" long and 4 1/4" high (NOT including the basketry handle).
