It says やきものの里 有田の器 (Yakimono no sato Arita no Utsuwa), implying that this is a porcelain made in a place called Arita.
They have some unique pottery techniques that make their porcelain widely known in Japan as 有田焼 (Arita ware Arita ware - Wikipedia).
May not have to be made in Arita particularly if the same technique was used...not sure.
Also I'm not familiar with its unique techniques or history behind it, so I can't tell if your bowl is really 有田焼 or not.
To fix the orientation you can rotate the picture 90deg counter-clockwise
