Japan visa-free entry for Thais — 15-day biometric ePassport path
Thai nationals holding an ICAO-compliant biometric ePassport can enter Japan visa-free for tourism stays up to 15 days per visit. Requirements: (a) the passport must be biometric/ePassport standard (look for the ICAO ePassport symbol on the cover); (b) return/onward ticket; (c) proof of sufficient funds; (d) confirmed accommodation. No pre-registration needed — unlike Indonesia, Thailand does NOT require embassy registration. For stays longer than 15 days, or non-tourism purposes, you must apply for a visa in advance.
