Our verdict
Sakura Mobile is a mobile virtual network operator selling sim only plans on the docomo network, aimed at people in Japan who want short terms and rollover data. Entry pricing starts at ¥2,480 a month, and every tier is month to month, so the price you start on is the one you renew.

Pros and cons
Pros
- Every plan is sim only and sold on 1 month terms, so there is no long contract to escape.
- Data rollover carries unused data forward, and billing covers rolling and prepaid, which includes rolling and prepaid.
- Support runs on email, phone and help centre, so email, phone and a help centre are all available.
- Runs on the docomo network with eSIM, hotspot sharing and support for the newest generation of mobile data.
- Entry pricing of ¥2,480 a month, with a voice and data option alongside the data only tiers.
Cons
- Sakura Mobile is a mobile virtual network operator, while GETESA, Lonestar Cell MTN and yesss! all sell as networks, so the seller type differs from every alternative listed here.
- Entry pricing of ¥2,480 ranks 205 of 258 brands on price, which is mid table rather than a standout figure.
- A single market is listed, JP, so anyone wanting service in another country has nothing here to weigh up.
- Support runs on email, phone and help centre only, with no live chat option in that list.
Who it suits
- People in Japan who want a sim only line on the docomo network and can stop at short notice.
- Newcomers and travellers who want an eSIM set up before a physical card arrives.
- Households that want voice and data together without a long contract term.
Who should look elsewhere
- GETESA, if you would rather buy from a network operation, as it sells as a network where Sakura Mobile is a mobile virtual network operator.
- Lonestar Cell MTN, for readers who want a network seller instead of a virtual one running on the docomo network.
Core features
Every plan is sold sim only, so you bring your own handset and pay for the line rather than a device. Support covers the newest generation of mobile data, and eSIM is available for anyone who would rather set the line up without waiting for a physical card. Data rollover is included, which means unused data carries into the next month instead of expiring, and hotspot sharing is supported, so a phone can act as a router for a laptop or tablet. The allowance is the main thing that changes between tiers, and the same features sit on each one.
The company behind it
The company behind the plans is Og inc., based in Japan and trading since 2014. Support runs on email, phone and help centre: email, phone and a help centre. That mix means questions can be sent in writing when they are not urgent, taken in a call when they are, and looked up in the help centre before anyone needs to make contact. The operator is a business in its own right, buying capacity on the host network and selling the plans under its own name.

Frequently asked questions
What does Sakura Mobile cost to start?+
Entry pricing is ¥2,480 a month on the smallest data allowance listed. A larger data only tier and a voice and data tier sit above it on the same price page, and each one is published as month to month, so the rate shown is the rate that carries on month after month rather than a welcome price that lapses.
How long am I tied in?+
Plans are sold on 1 month terms, and the billing options are rolling and prepaid, which covers rolling and prepaid billing. A long contract period is not part of the plan range, so the commitment you take on is as short as the billing cycle you choose.
What do the plans include?+
Each plan is sim only, so you supply the handset, and the data allowance is what changes between tiers. Data rollover is included, hotspot sharing is supported and eSIM is available, which means one line can serve a tablet and a laptop as well as the phone it sits in.
Can I set the line up with an eSIM?+
Yes, eSIM is available on the plans. That suits anyone setting up before a physical card arrives, or anyone who wants the mobile line kept separate from the phone they use for everything else. The newest generation of mobile data is supported as well, and the same line can share its connection as a hotspot.
Which network does the service run on?+
The host network is docomo, and Sakura Mobile is a mobile virtual network operator, meaning it buys capacity on that network and resells the plans under its own name. Coverage in a given place therefore follows the host network, and Sakura Mobile is the billing party rather than the network itself.
Where is Sakura Mobile available?+
The company is based in Japan and lists JP as its market, so the plans are aimed at people living in Japan rather than at travellers looking for a home network elsewhere. A single market is listed, and the prices are quoted in Japanese yen.
How do I get help?+
Support runs on email, phone and help centre, which covers email, phone and a help centre. Email suits questions that can wait, the phone line handles anything urgent, and the help centre lets you look up common issues without contacting anyone first.
Who is this plan for?+
It suits people in Japan who want a sim only line on the docomo network, a 1 month term and data that rolls over, plus anyone who wants an eSIM set up quickly. It is less useful if you would rather hold an account with the network's own operation.
