Japanese bank book printed transaction messages in half-width kana. In Japan, the Nationalwide Banking Data Communication System was established in 1973, and it only handled latin, numbers, and katakana within 20 characters. The system was replaced by ZEDI (the Nationalwide Banking EDI System) in 2018, which can handle hiragana and kanji with variable length characters.
