Japanese Ginger/Biscuit Jar/Tin?

I can't tell if this is for ginger or biscuits. I'm going to guess maybe biscuits as it's more of a bisciuty tin shape. It cost us only a few euros in a car boot sale and we loved the art on it so we took it and it currently sits on our dresser.
The stamp on the bottom reads 'Samurai' hand painted and made in Japan. I'd love to know are there more similar pieces out there and how popular are these pieces- my guess is it isn't that valuable and it was just made for the tourist market.
