There is also a Japanese dish called yakisoba. When I first saw yakisoba on a menu, I though that it was a kind of soba dish because of "soba" in the name. But apparently, it has nothing to do with soba, it's not made with buckwheat noodles.
Yakisoba is made with egg noodles and tastes much different. Soba tastes more plain because it's actually healthier than egg noodles. Yakisoba is fried so that's probably why it tastes better and I've heard it being referred to as the Asian junk food.
I actually like both soba and yakisoba and wouldn't mind eating either one. But I wanted to note the difference for people who want to have buckwheat noodles and not egg noodles. You might get confused and order the wrong one.
