Oriental Bowl White in padded box

Description

Oriental Bowl White in padded box. Condition is "Used". Shipped with USPS Priority Mail.
I tried to use a translation program but was unsuccessful- it either said ‘MEMBER’ or ‘SUMMER’ for the words on the bottom- any help would be appreciated.
The bowl is white in color with some writing on the bottom- shown in photos
I picked this up at an estate sale from a retired military officer - no one there had details about it. The box is old and worn - bowl is padded safely in the box.
