HONEST PROVIDER REVIEW
Sakura Mobile review: is it worth it for Japan?
Sakura Mobile is one of the few Japanese providers built for foreigners — everything in English, a travel eSIM with truly unlimited 5G, and SIMs for residents too. It’s a great fit for some people and the wrong call for others. Here’s the honest version, including when a cheaper eSIM beats it.

THE HONEST VERDICT
Pick Sakura ifyou want everything in English, truly unlimited 5G, or a reliable name for a longer stay — and you don’t mind paying more. Skip it if you just need light data for a short trip; a cheaper eSIM (Airalo, Ubigi) will do.
Check Sakura Mobile’s plans (ad) →Pros
- ＋ Full English support — sign-up, billing, help, all in English
- ＋ Truly unlimited 5G (au), no daily speed cap on that plan
- ＋ Japan-based company; reliable for arrivals and longer stays
- ＋ Both travel eSIM and resident SIM options
Cons
- − Costs more than Airalo / Ubigi / many data-only eSIMs
- − Billed in JPY (foreign-card fees/FX may apply)
- − The cheaper 4G plan throttles after ~3GB/day
- − Overkill if you only need light data for a short trip
Travel eSIM: the plans
Sakura’s travel eSIM comes in two flavors. The 5G Unlimited plan (au) is genuinely unlimited at high speed — from around ¥5,000 for 7 days (indicative), scaling up to about a month. The cheaper 4G plan (docomo) gives high speed up to ~3GB/day, then slows to ~200kbps and resets the next day — fine for maps and messaging, not for heavy streaming. Both install before you fly and activate when you land.
Prices are indicative and billed in JPY — always check the live price before you buy.
Honestly: cheaper eSIMs exist
If you just need data for a short or light trip, a data-only eSIM like Airalo or Ubigiis usually cheaper. What you give up is English support and (on Airalo’s “unlimited”) a ~3GB/day cap. Not sure which fits you? Our 2-minute eSIM check compares them honestly by your trip length and data — no ranking spam.
For residents, not just tourists
Just moved to Japan? Sakura also offers SIMs with a real Japanese number and English support — useful right after arrival, before you’re set up for a cheaper Japanese-only carrier. See the trade-offs in our resident SIM guide, and remember you can switch later (MNP) without losing your number.
Who should pick Sakura Mobile
- You want zero language friction. Everything in English is worth the premium for many travelers and new arrivals.
- You stream or tether heavily.The 5G unlimited plan has no daily cap, unlike most “unlimited” travel eSIMs.
- You’re here a while. A Japan-based provider is reassuring for longer stays or as a new resident.
