Japan to Cambodia visa requirements

Japanese ordinary passport holders need a visa for Cambodia. The easiest option is the official tourist e-Visa (T-class): single entry, 30-day stay, about US$36 all-in, approved in roughly 3 business days. Visa on arrival (US$30) is also available at major airports and land borders. All air arrivals must additionally complete the free Cambodia e-Arrival Card. Japan is not on Cambodia's visa-exemption list for ordinary passports (only diplomatic and official passport holders enjoy a 90-day waiver). For tourism, a Japanese national must obtain a Cambodian tourist visa. Two practical channels exist: the official online e-Visa at evisa.gov.kh and visa on arrival at international airports and major land crossings. The e-Visa is recommended because it removes queueing on arrival and confirms entry eligibility before flying. The tourist e-Visa (Type T) grants single entry, a maximum stay of 30 days, and is valid for use within 3 months of issue. The total cost is US$36 (a US$30 government visa fee plus a US$6 service charge), and approval normally arrives by email within about 3 business days. Visa on arrival costs US$30 (cash, USD) and is available at Phnom Penh (Techo), Siem Reap-Angkor, and Sihanoukville airports plus several land borders, though it requires queuing and a passport photo. Separately, since the digital system became mandatory, every air traveler must submit the free Cambodia e-Arrival Card within 7 days before arrival; this is an immigration form, not a visa, and does not replace the visa. Passports must be valid at least 6 months beyond arrival with at least two blank pages. Stays can usually be extended once in-country through an immigration agent. Sources conflict slightly on whether Japan is visa-free; authoritative sources (Cambodia's Foreign Ministry exemption list and the official e-Visa portal) confirm Japan is NOT exempt for ordinary passports, so a visa is required.
