常见问题
Can I use my eSIM on the Shinkansen (bullet train)?
Yes, coverage is generally good along Shinkansen routes on all major lines. Brief signal drops occur in tunnels. The trains themselves do not provide Wi-Fi on all lines — your eSIM is the more reliable option.
Does Google Maps work for Tokyo subway navigation?
Yes, and it's excellent. Google Maps accurately handles Tokyo Metro, Toei Subway, and JR lines including interchanges. It shows exact platform numbers and walking times between lines at major stations like Shinjuku and Shibuya.
Will my eSIM work underground on the Tokyo Metro?
Yes. Tokyo Metro has strong underground connectivity at most stations. You'll have signal on platforms and in trains between stations on most lines.
Will the eSIM work in rural Hokkaido?
Yes, major carriers provide strong coverage across Hokkaido including Sapporo, Hakodate, and Asahikawa. Very remote mountainous areas and ski resorts at high elevation may have limited signal.
Can I use Google Translate camera mode for Japanese menus?
Yes, and it works well for standard Japanese restaurant menus. The camera mode translates hiragana, katakana, and most kanji in real time. Download the Japanese language pack offline in case you're somewhere with slow data.
Is Japan moving toward cashless payments?
Increasingly yes, but Japan is still partly cash-based. Convenience stores, most restaurants, and transport accept IC cards and card payments. Small izakayas and traditional establishments may be cash-only — carry some yen.
How is coverage at Mount Fuji?
The Fuji Five Lakes area and Kawaguchiko have good coverage. The Fujisan trail itself has signal at the lower stations but becomes unreliable above Station 8 (3,400m). Download offline maps for summit day.
Does the eSIM work for QR code menus and restaurant reservations?
Yes. QR code menus require a data connection to load. Online reservation systems like TableCheck, Omakase, and Google Maps' booking integration all work with your eSIM data connection.

日本 eSIM指南
您的eSIM将连接到日本的主要运营商：
可用网络：5G
Japan is the country where mobile data earns its keep most clearly. Google Maps is how you navigate the Tokyo subway — 13 overlapping lines, color-coded and complex enough that even Japanese residents consult it daily. Google Translate's camera mode on kanji menus at izakayas and ramen shops is practically essential outside tourist-focused restaurants. The Hyperdia or Japan Official Travel App handles Shinkansen route planning including exact platform numbers and transfer times at busy interchange stations.
Japanese mobile networks are among the most reliable in the world. NTT Docomo, KDDI (au), and SoftBank provide dense 4G LTE coverage nationwide. 5G is expanding rapidly in Tokyo, Osaka, Nagoya, and Fukuoka. Even rural Hokkaido farmland and mountain areas tend to have signal. The Shinkansen routes are covered; brief drops occur in tunnels. The Tokyo Metro has full underground coverage at most stations.
Beyond navigation, a few apps change how Japan works for visitors. LINE is Japan's dominant messaging app — accommodation, tour operators, and restaurants often contact you via LINE. Tabelog is the definitive Japanese restaurant rating app (scores are strict; a 3.5 is genuinely good). TableCheck and Omakase handle online reservations for higher-end restaurants that fill weeks ahead. QR code menus are universal since COVID — you'll scan one at almost every sit-down restaurant.
The Suica IC card (contactless transit and payment card) is now available on iPhone and Android via Apple Pay/Google Pay. It works on Tokyo Metro, JR lines, buses, and as payment at convenience stores and many vending machines. Having your eSIM data active means you can add credit to your digital Suica remotely and check your balance without hunting for a machine.
Local SIM cards at Japanese airports are available from IIJmio and several tourist-targeted brands — mostly data-only, which is the same limitation as most travel eSIMs. The airport counters can have queues after international arrivals. An eSIM installed before your flight means you're navigating to your hotel with Suica loaded and Google Maps running before you leave Narita or Haneda.
