blue porcelain lotus flower rice bowls, vintage china dishes made in Japan

Beautiful blue porcelain rice or noodle bowls (or tea bowls?) made in Japan, 80s or 90s vintage, Artmark label. We love the lotus flower shape and the sky blue color!

This is a set of four bowls measuring about 4 1/4" across the rim x 2 1/4" tall. The whole set is in excellent condition - these have had very little if any use.
