Bolero San:
The writing on the other side reads Douman Tamakin (Characters 堂満玉金) Maybe you can copy and paste and do a little research on finding out more about this pot. I do not know if this is a place or name, but sounds like a name.
One thing to notice, (and I do not know if this is camera angle etc.) but the characters do not seem to align. Slants down as you read left to right. Another is if you read it from right to left it would read kintama....(you can look up that Japanese slang for yourself).
If you are using it for a display...would recommend putting an informally styled deciduous or fruiting tree (quince based on kintama reference above
)into this pot and using the landscape side, hiding the characters.
