The Japanese notation system uses Japanese characters for pieces and promotion indication and uses Japanese numerals instead of letters for ranks. Movement type aside from drops is not indicated, and the conventions for resolving ambiguity are quite different from the western system. As examples, the western Rx24 would be ' in Japanese notation, +Rx24 would be ', S-21+ would be ', S-21= would be ', and N65-53+ would be ' showing that the leftmost knight jumped (implicitly from the 65 square), which distinguishes it from ' in which the rightmost knight jumped.
