Chinese or Japanese porc/china very nice hand work, not sure of the era or the markings??

I WAS GIVEN THESE BY MY MOTHER IN LAW. ONE IS A BOWL, THE OTHER IS SOME KIND OF DISH WITH A LID, AND A SMALL AND MEDIUM CUP. I AM NOT SURE IF CHINESE OR JAPANESE. IM NOT SURE WHAT THE MARKS ON THE BOTTOM MEAN. OR WHAT ERA THEY ARE FROM. NOT SEEN ANYTHING LIKE THEM. ANY INFORMATION WOULD BE A BIG HELP. LESA
