eSIM in Japan for residents: which carriers allow it with a residence card

You can get an eSIM in Japan as a resident if the carrier accepts your residence card (在留カード) in its online ID check. As of October 2026, ahamo accepts it but not cards issued from June 14, 2026. povo needs at least 90 days of stay left. Sakura Mobile sells eSIM plans in English and accepts foreign cards. An eSIM is a SIM built into the phone, so you get no plastic card in the mail.

Why is the ID check harder for eSIM?

Everything happens online, so the carrier must check your ID on screen. According to 総務省, IC chip reading has been required in principle for online contracts since April 1, 2026 (令和8年4月1日). povo, for example, asks you to read the chip in your card and take a face photo.

From April 2027, 総務省 says IC chip reading becomes required in principle for in-person contracts too, and data SIMs will also be subject to ID checks. Plan for the rules to get stricter, not looser.

Which carriers take a residence card for eSIM?

This table covers what each carrier’s own pages say. Where a page says nothing about eSIM, we say so.

The povo and Rakuten Mobile pages do not mention eSIM. Check the eSIM steps at sign-up. We could not read LINEMO’s pages, so we make no claim about them.

What blocks a new residence card?

Two carriers published limits on newer cards, as of June to October 2026.

• ahamo: it does not accept second-generation residence cards (第二世代在留カード) issued from June 14, 2026, or cards that carry the My Number Card function (特定在留カード). It suggests a mass retailer or dealer that handles ahamo sign-ups.
• Rakuten Mobile: the phone check fails if no address was registered when the card was issued, or if you have not updated your address since June 14, 2026. Apply at a shop instead. Rakuten also says home verification is not available to foreign nationals.

Check the issue date and the back of your card before you start.

How do I apply for an eSIM with a residence card?

Which eSIM works best without a Japanese credit card?

Sakura Mobile is the clearest option in English. As of October 2026 it lists Voice+Data SIM/eSIM plans at 5GB ¥3,278, 15GB ¥3,828, 30GB ¥4,378 and 40GB ¥5,478 a month, with calls and SMS charged on top. A data-only eSIM costs ¥3,828 for 30GB. The activation fee is ¥5,500 on every plan, with no separate eSIM fee listed. Support is in English seven days a week, and the minimum term is one month.

For an emailed eSIM, Sakura Mobile asks for a residence card with your current address, a Japanese driver’s license showing your current address, or a My Number Card. Its FAQ says a passport or residence card is enough, which conflicts with this, so bring the card.

Mobal says it also sells eSIMs on the docomo network. We could not read its eSIM page, so check the price and ID rules there. Mobal’s voice-only SIM needs a full valid passport, not a copy, and customers must be 18 or over.

ahamo costs less: the 30GB plan is ¥2,970 a month as of October 2026. From December 1, 2026 its base fee becomes tiered, starting at ¥3,135 for 40GB. The ahamo pages we read do not mention English support, and you need a credit or cash card in your name.

Can I get an eSIM with a short stay left on my card?

It depends on the carrier. povo needs 90 or more days left. docomo says that if less than three months remain, you pay by credit card in your own name, and installment plans may not be available if the card expires before the contract ends. ahamo’s page only says the card must be unexpired.

Your period of stay (在留期間) matters for the contract, not only the ID check. Questions about renewal belong with the immigration bureau or a licensed immigration and administrative specialist (行政書士).

What if the online ID check keeps failing?

Go to a shop. Rakuten Mobile accepts the original residence card in store (copies are not accepted) and uploads both sides, or the front only for a 特定在留カード. ahamo points newer card holders to retailers that handle its sign-ups. If your card address is 未定, povo suggests a My Number Card instead.

If a carrier turns you down and you think it is wrong, a municipal consumer center (消費生活センター) can advise you.
