Narita to Denver (NRT–DEN) — Airlines, Schedules & Connections

Japanese passport holders can enter the United States for up to 90 days under the Visa Waiver Program (VWP) with an approved ESTA (Electronic System for Travel Authorization). Apply at esta.cbp.dhs.gov at least 72 hours before departure. ESTA costs $21, is valid for 2 years, and allows multiple entries. You cannot extend a VWP stay or change immigration status. For stays beyond 90 days, apply for a B-1/B-2 visa at the US Embassy in Tokyo ($185 application fee).

ESTA asks for passport details, employment information, and security questions. Approval is usually instant but can take up to 72 hours. At US immigration, CBP officers may ask about your trip purpose, length of stay, and accommodation. Global Entry ($100, valid 5 years) gives you automated kiosks at major airports, skipping the main immigration line. Apply at ttp.cbp.dhs.gov and interview at the US Embassy Tokyo or at a US airport on arrival.
