Oiling Ginkgo wooden cutting board?

Hello, I purchased a cutting board (chopping board) made of gingko wood when I was in Japan a few years ago. I wonder if I should be oiling the board like I would with other wooden cutting boards? (The information that came with the board was in Japanese, so I’m not sure what it said!).
Thanks and great job on a very interesting website.
