Common Mistakes to Avoid

Mastering Business Kanji

Business emails require specific kanji that you might not encounter in casual study: 拝啓, 敬具, 弊社, 御社, 拝見. Learning these kanji with Kanjijo’s SRS flashcards and mnemonic stories helps you internalize them through spaced repetition rather than rote memorization.
