If you are a foreigner living in Japan and searching for a mobile plan that actually understands your situation, you have probably come across Sakura Mobile. This review breaks down everything you need to know — plans, pricing, language support, how to apply, and honest pros and cons — so you can decide whether it is the right SIM for you.
What Is Sakura Mobile?
Sakura Mobile is a Japan-based MVNO (Mobile Virtual Network Operator) designed specifically for foreign residents and visitors in Japan. Unlike the big three carriers — docomo, au, and SoftBank — which can be difficult to navigate for newcomers due to language barriers and strict payment requirements, Sakura Mobile positions itself as a foreigner-friendly alternative with English support and flexible sign-up conditions.
It offers both SIM card plans and pocket Wi-Fi rentals, catering to people who need connectivity from their first day in Japan all the way through long-term stays.
Who Is Sakura Mobile For?
Sakura Mobile is particularly suited to:
- Foreign residents who have just arrived in Japan and do not yet have a Japanese credit card
- People who want English-language customer support
- Students, working holiday visa holders, and expats on mid- to long-term stays
- Tourists or short-term visitors who need a reliable data connection
If you relate to any of these situations, Sakura Mobile is worth a serious look.
Sakura Mobile Plans at a Glance
Sakura Mobile offers several types of plans. The details below are a general guide — plans, prices, and conditions change regularly, so always confirm the latest information on the official Sakura Mobile website before signing up.
SIM Card Plans
Sakura Mobile's SIM card plans generally run on a major Japanese network, providing solid coverage across the country. Plans typically include data-only and voice + data options. Monthly data allowances vary by tier, and some plans offer unlimited or high-cap data at different price points.
Short-Term and Long-Term Options
One of the advantages of Sakura Mobile is flexibility. They offer plans suitable for stays as short as a few weeks as well as ongoing monthly plans for long-term residents. This makes it a practical stopgap SIM right after arrival while you sort out your bank account and other paperwork.
Pocket Wi-Fi Rental
For those who prefer not to swap SIM cards, or who need to share data across multiple devices, Sakura Mobile also offers pocket Wi-Fi rentals. This can be a convenient option for short visits or for the transitional period just after landing in Japan.
What Documents Do You Need to Apply?
To get a contract SIM in Japan, you generally need the following. Requirements can vary by plan, so check the official site for your specific situation.
- Residence card (在留カード, Zairyu Card): Required for long-term contract plans to verify your legal status in Japan
- Japanese address: Needed so the SIM card can be mailed to you
- Payment method: Sakura Mobile is designed to accept payment options that work for foreigners — check the current accepted methods on their site, as requirements may have changed

Key Things to Compare Before You Decide
Sakura Mobile is not the only foreigner-friendly option in Japan. Before committing, it is worth comparing a few key factors:
| Factor | What to Check |
|---|---|
| Monthly price | Compare total monthly cost including taxes and any option fees |
| Data allowance | How many GB per month, and what happens when you exceed the limit |
| Voice calls | Whether the plan includes calls or is data-only |
| Japanese credit card required? | Sakura Mobile is generally flexible here; confirm current terms |
| Contract length and cancellation | Month-to-month vs fixed-term; any early cancellation fees |
| Language support | Availability of English customer service |

Other providers worth comparing include GTN Mobile, which also accepts a residence card, offers multilingual support, and does not require a Japanese credit card, making it a strong alternative for long-term residents. Mobal is another option that requires neither a Japanese credit card nor a Japanese bank account and offers English support.
