Official: Japanese · English: Limited · Local language: Recommended
Japanese strongly recommended for daily life beyond corporate Tokyo. English is limited in shops, hospitals, and bureaucracy — translation apps help but a friction tax remains for non-speakers.
Official: Korean · English: Moderate · Local language: Useful
Korean is the daily-life default. English usable in expat-heavy neighborhoods (Itaewon, Hannam) and international firms; outside that, limited. Hangul is easy to learn even if speaking is slow.
