Yes, you got it right. Dai Nippon, Inbe-sei (Imbe is also OK)
Actually I can't read that very last kanji. It could be 製, but it could also be something else (陶 or 焼) or something. But 製 is probably the most likely. At any rate, it doesn't really change the overall meaning/intent.
Made by Inbe. Made by the Inbe kiln. etc...
