If you visit Japan, please try "Sashimi (sliced raw fish)," "Soba/Udon (noodles)," and "Nihon-shu (Sake)." They're all traditional Japanese foodstuffs; you can have them everywhere you visit in Japan. They are the first three items that come to mind when I considered recommending Japanese food to people from abroad. I am a big fan of "Sashimi." It is generally pricey, so I only eat it sometimes. If you can try it, please don't forget to use "Shouyu (soy sauce)." We rarely have "Sashimi" without soy sauce because it has the magic to make "Sashimi" tastier. "Soba/Udon" are a popular noodles in Japan. Interestingly, their flavor is different depending on the area. In the eastern region, they prefer the strong flavor. I have yet to try the eastern version of that. Since living on Japan's western side, I'm familiar with a lighter flavor. I'm not a "Nihon-shu" guy (honestly, I prefer European wine), but it is the national liquor in Japan. Its flavor changes depending on the origin. You will enjoy a variety of flavors if you are a liquor lover.
