eSIM wins for most trips. It's cheaper, faster to activate, and requires no airport visit. The exception: if you need voice calls or SMS, or if your phone is older than 2018, a physical SIM from Sakura Mobile is the right choice.

FAQ

Common Questions

1. Is eSIM better than a SIM card for Japan?

For most tourists visiting Japan for 1–30 days, an eSIM is the better choice. It is cheaper, faster to set up, and requires no visit to an airport kiosk. The main limitation is that most Japan eSIMs are data-only — if you need voice calls or SMS, a physical SIM (Sakura Mobile) is the better option. eSIM also requires a compatible device — most smartphones made after 2018 and most current-generation tablets qualify.

2. Can I get a physical SIM at Japan airports?

Yes. Physical SIM cards and eSIM QR codes are available at vending machines and kiosks in most major Japanese airports, including Narita, Haneda, Kansai, and Chubu. However, airport prices are typically higher than when you pre-order online. Pre-ordering from Sakura Mobile before you fly is usually cheaper and avoids any queue time on arrival.

3. Which is cheaper, eSIM or physical SIM for Japan?

eSIMs are significantly cheaper for short trips. A Japan eSIM from Airalo starts at $4.50 for 7 days / 1 GB, while a physical tourist SIM from Sakura Mobile typically starts around ¥3,000–¥4,000 (~$20–$27) for a basic plan. For stays of 1 month or longer, the gap narrows and a physical SIM may offer better per-day value with voice capability included.

4. Do I need to be in Japan to activate a physical SIM?

Generally, yes — a Japan SIM card must be inserted and activated in Japan. However, Sakura Mobile ships SIMs internationally, so you receive the card before you travel and insert it when you land. Some providers also offer pre-activated eSIM QR codes that you scan before departure and activate on arrival.

5. What happens if my eSIM doesn't work in Japan?

First, ensure the eSIM profile is toggled on in your phone's settings and that your device is not in airplane mode. If you still have no signal, check that the eSIM is set as the primary data line. Contact your eSIM provider's support — Airalo, Holafly, and eSIM Go all offer online support. As a backup, 7-Eleven convenience stores in Japan sell physical SIM cards at reasonable prices.
