Before You Leave

Download Google Translate – The camera feature instantly translates Japanese menus and signs
Get a Suica Card – This IC card works on all Tokyo/Osaka trains and even convenience stores. Pro tip: iPhone users can add it to Apple Wallet
Check your phone compatibility – Most iPhone XS and newer, plus Samsung S20+ and Google Pixel 3+, support eSIM

Once You Arrive

Don't talk on trains – It's considered rude. Set your phone to silent (called "manner mode" in Japan)
Bring cash – Many small restaurants and temples are cash-only. 7-Eleven ATMs accept foreign cards
Use the left side – Walk and stand on escalators on the left (except Osaka, where it's right!)

Activate before landing – Install your esim for japan while on airport WiFi, then enable it when you deplane
Screenshot important info – In case of temporary signal loss in rural areas, have hotel addresses and confirmation numbers saved offline

What is an eSIM? (And Why It's Perfect for Japan)

An eSIM (embedded SIM) is a digital SIM card built directly into your smartphone. Unlike traditional plastic SIMs, you don't need to physically swap anything—you simply scan a QR code or download a profile, and you're connected to a local Japanese network within minutes.

Key advantages for travelers:

Dual SIM capability – Keep your home number active for banking/2FA texts while using Japanese data
No physical swapping – No risk of losing your home SIM card
Instant delivery – Buy today, travel tomorrow
Eco-friendly – No plastic waste
