The alternative keyset on the UK01-0010 is katakana, not kanji. In modern times it's usually used for foreign words or for emphasis, but in the 80s it was often the only Japanese writing system available on computers, because its characters have the simplest shapes and are legible on the lowest resolution screens. Katakana (カタカナ): simple angular shapes, phonetic syllabary. Hiragana (ひらがな): simple but more curved shapes, phonetic syllabary. Kanji (漢字): complex shapes, looks like traditional Chinese, logographic.
