Notice: If your browser does not load the calculator properly (boxes are empty), switch your browser to japanese language encoding. In IE, either right click or go to the view menu, go to encoding, and select from the list Japanese (Auto-Select). If its not listed under there you may need to go under the more menu. In Firefox its very similar, go to the view menu, and under character encoding, find Japanese (SHIFT-JIS). You may need to look under More Encoding. Note that this issue will hopefully be fixed shortly.
