Nutritional Info for Asian/Japanese/Korean Sweet Potato (satsumaimo and/or goguma)

Does any one have a source for this information? I'm looking for the data on the chestnut-flavored tuber with red skin and creamy-colored flesh that turns golden when cooked. It's my understanding that this tuber is less sugary and more starchy than the more common (in the States, anyway) orange-flesh "jewel yam."

Elsewhere on Paleohacks I found a value of "100g raw yields 132 calories." (From this thread: http://paleohacks.com/questions/131373/satsumaimo-japanese-variety-versus-sweet-potato-american-orange-variety ). I am wondering if anyone has a source on the rest of the data? Perhaps someone with a reading knowledge of Japanese or Korean might be able to get this information from a Japanese or Korean site?

Thank you!

This says YAM.  As alwasys, Yam is often confused with Sweet Potato, Asian, American, or otherwise.  They are two different species.  This link could be for a yam, or a sweet potato.

I have googled more deeply, and solved most of the mystery. But I'd still like to know how much of the carb comes from sugar, and what (if any) Vitamin A/beta carotene content these guys have.

I'm curious about this one myself. I've recently decided these are just too cloyingly sweet for me, but I do eat one occasionally and I've casually wondered.
