Product details
Japan is an island nation in East Asia made up of four main islands — Honshu, Hokkaido, Kyushu and Shikoku — plus more than 6,800 smaller ones. Its capital, Tokyo, is one of the world's largest cities, with a metropolitan population of over 37 million. The country is famous for its unique blend of ancient tradition and cutting-edge technology, from thousand-year-old temples to the Shinkansen bullet-train network and the neon-bright Akihabara district.
- Language: Japanese. English is limited outside central Tokyo, Osaka and Kyoto.
- Currency: Japanese yen (JPY, ¥). 1,000,000 VND ≈ ¥5,800.
- Time zone: GMT+9 (2 hours ahead of Vietnam).
- Power outlet: Type A (two flat pins), 100V / 50–60Hz. An adapter is needed for Vietnamese devices.
- Visa: Vietnamese travelers need an entry visa, applied for at the Embassy of Japan.
Japan has one of the best telecom infrastructures in the world, with three major operators: NTT Docomo, SoftBank and KDDI (au).
- 4G/LTE coverage: Near 100% of the territory, including mountain regions and small islands.
- 5G: Widely deployed in Tokyo, Osaka, Kyoto, Nagoya, Sapporo and Fukuoka. Average download speeds of 200–500 Mbps in major cities.
- Shinkansen coverage: Continuous, even through long tunnels.
- Public Wi-Fi: Available at train stations, Starbucks, 7-Eleven, Lawson and FamilyMart, but typically slow and requires email signup.
Our travel eSIM for Japan suits trips of 3 to 30 days and works the moment your plane lands at Narita, Haneda, Kansai (Osaka) or Chubu (Nagoya).
- Tokyo — A dynamic capital with Shibuya, Shinjuku, Asakusa (Sensoji Temple), Tokyo Skytree and Disneyland.
- Kyoto — The ancient capital, home to over 1,600 temples, the Arashiyama bamboo forest, the Golden Pavilion (Kinkakuji) and the geisha district of Gion.
- Osaka — A foodie paradise with Dotonbori, Osaka Castle and Universal Studios Japan.
- Hokkaido — Sapporo (Snow Festival), Furano (lavender fields) and the Noboribetsu hot springs.
- Mount Fuji — Japan's iconic peak, best viewed from Lake Kawaguchi in autumn or winter.
- Payments: Japan still favors cash. Carry yen for small shops, temples and rural taxis. Suica/Pasmo cards combine transit and e-wallet usage and are extremely convenient.
- Trains: A JR Pass saves a lot for travelers visiting multiple cities. Buy it before arriving in Japan for a lower price.
- Etiquette: No tipping at restaurants, no phone conversations on trains, and no littering (public trash bins are rare).
- Travel seasons: Cherry blossoms in March–April, autumn leaves in November, snow in December–February. Avoid Golden Week (late April to early May) when prices spike.
- Language: Download offline Japanese in Google Translate before you arrive — English is limited.
An eSIM keeps you connected the moment you touch down in Japan — no SIM-swap queues, no hunting for free Wi-Fi. With Tokyo Metro and JR's complex rail network, a stable connection for Google Maps, language translation and Tabelog restaurant bookings is essential. Our eSIM roams across all three major operators, so you stay covered in rural Hokkaido, on Okinawa or atop Mount Fuji.
