About Japanese and English
Japanese (日本語) is written in the Kanji, hiragana and katakana script and spoken by about 125 million, mainly in Japan. Japanese mixes three scripts with no spaces between words, and business documents rely on set polite (keigo) expressions that have no direct English equivalent.
English (English) is written in the Latin script and spoken by about 1.5 billion, mainly in the UK, the US, Canada, Australia, Ireland, India and most international organisations. US documents write dates month-first (04/10/2026 is April 10) while British and most other documents write them day-first, so check dates carefully when moving between regions.
