Bank Accounts, SIM Cards, and What's Left of the Paycheck

India Japan Kaizen — Career Bridge Series, Part 5

Part 1 of this series mapped five industries hiring Indians into Japan. Part 2 covered the visa process, Part 3 named the companies and registries that separate a real recruiter from a scam, and Part 4 priced out what an offer letter's salary number actually buys once reikin, shikikin, and a guarantor fee are subtracted before the first paycheck even lands. All four parts end at the same point: someone has a visa, an apartment, and a start date. None of them cover the week right after that, when two of the most ordinary errands in any country — opening a bank account and getting a phone number — turn out to be unusually hard in Japan, because neither is really possible without the other already in hand. 2026 has added two fresh complications to that chicken-and-egg problem since Part 4 published, on top of a tax and social-insurance picture that quietly moves every salary figure Part 4 quoted by a few thousand yen in either direction.

The Six-Month Clock, and a Card Format That Just Changed Mid-Race

Most Japanese banks still apply an informal six-month residency expectation before opening a standard account, tracing back to the Foreign Exchange and Foreign Trade Control Law's anti-money-laundering checks; someone with three to six months left on their status can usually only get a restricted account, if that. Japan Post Bank remains the most commonly cited exception, generally accepting new arrivals without insisting on the six-month wait. Almost every bank now also wants a Japanese phone number on file for SMS verification — which is exactly the number a brand-new arrival doesn't have yet.

A fresh wrinkle landed in the middle of this year's arrivals: Japan began issuing a new-format residence card on 14 June 2026. Seven Bank — a widely used option for international transfers and ATM-based banking — posted a notice on 8 June saying it would temporarily suspend account-opening procedures that rely on the new-format card while it finishes updating its systems, though cards issued on or before 13 June 2026 are unaffected and can still be processed normally. No bank, Seven Bank included, has published a public date for when full support resumes. In practice, that means someone whose card happens to be printed just after the cutover has no way to know in advance whether their arrival falls inside or outside that gap.

A Push to Make My Number Mandatory for Every Account

In May 2026, Japan's ruling LDP called on the government to consider making ownership of the My Number card — the separate, still-optional personal ID card distinct from the residence card every foreign national must already carry — mandatory, with no penalty yet proposed for noncompliance. Alongside it, the party is pushing for mandatory registration of bank accounts under each person's My Number, framed around faster subsidy payouts rather than banking access specifically. Both ideas are expected to be weighed into the government's basic economic and fiscal policy guidelines, due this summer. Neither is law yet, but Part 2's account of the April 2026 N2 language rule showed how quickly a proposal in this immigration-and-finance space can move from announcement to binding — worth tracking for anyone arriving in the next year.

Breaking the Chicken-and-Egg Problem on a Phone Line

A mainstream carrier contract — NTT Docomo, SoftBank, au — typically wants exactly what a brand-new arrival doesn't have: a Japanese bank account or credit card, sometimes a guarantor, and a two-year commitment with an early-cancellation fee. Even with every document in hand, carriers can and do reject foreign applicants at the credit-screening stage without giving a reason. Two services exist specifically to route around that:

• Mobal. Lets someone apply from overseas before landing and ships a physical SIM or eSIM to a Japan address or hotel, so a working Japanese number already exists on arrival day.
• GTN Mobile. A foreigner-focused carrier that explicitly waives the credit card and bank account mainstream carriers demand, accepting convenience-store cash payment instead, with both a no-minimum-commitment plan and a cheaper longer-term one.

Once someone has a residence card and a Japanese address, a small number of credit cards are commonly cited as the easiest approvals for anyone with zero Japanese credit history — Rakuten Card and Amazon.jp's own co-branded card come up most often — making them a realistic bridge toward a mainstream carrier contract a few months in, rather than a first-week option.

What the 2026 Tax and Insurance Changes Do to Part 4's Numbers

Japan's Diet passed a reform on 31 March 2026 that temporarily raises the combined basic and employment-income deduction from ¥1.6 million to ¥1.78 million for 2026 and 2027, for anyone earning up to ¥6.65 million a year — both pieces rising ¥40,000 each, with the basic deduction's base amount moving from ¥580,000 to ¥620,000 and indexing to inflation from here on. The government's own estimate puts the resulting income-tax saving at roughly ¥4,000 to ¥36,000 a year per person, scaled to income — which lands toward the lower end of that range for the SSW monthly pay Part 4 quoted (¥221,400–233,000) and nearer the middle for the Engineer/Specialist visa's ¥313,200.

That saving is partly clawed back by a new child-support levy collected through health-insurance premiums starting April 2026, set at 0.23% of standard monthly compensation in FY2026 and scheduled to step up to 0.37% in FY2027 and 0.44% in FY2028 — it applies at every age, so it touches both of Part 4's visa categories. The underlying health-insurance rate itself was actually trimmed slightly for FY2026 on a national-average basis, which softens the levy's bite this year; separately, long-term-care premiums rose a few hundredths of a point, but that only applies from age 40, missing most of the new arrivals this series has tracked. One think-tank estimate — not an official government figure — puts the net social-insurance increase for Tokyo enrollees over 40 at roughly ¥3,200 a year on a ¥4 million salary and ¥6,200 a year on ¥8 million, smaller than this year's tax saving at most income levels, though the levy's own step-up schedule narrows that gap every year through FY2028.

One more change sounds bigger than it is for this part's purposes: a new “Special Defence Income Tax,” a flat 1% surtax on the income-tax amount, takes effect in January 2027 — not yet on anyone's 2026 payslip. It arrives paired with a cut to the long-running Reconstruction Tax from 2.1% to 1.1%, so the combined surtax that's sat on every paycheck since 2013 stays at the same 2.1% — just relabeled, and in the Reconstruction Tax's case stretched out to 2047 instead of ending in 2037. For Part 4's figures, that's a wash today and a line worth watching starting with next year's paychecks, not this year's.

What's Still Missing

No bank, Seven Bank included, has said publicly when new-format residence cards will be fully supported, so anyone issued one after 14 June 2026 still can't tell in advance whether they'll land inside that gap. The My Number banking-mandate idea remains a proposal, and neither the LDP's call nor any government statement so far says how a foreign resident's account registration would work once their residence status, and therefore their My Number record, changes. And nobody publishes a single table showing net take-home pay — after both the 2026 tax cut and the new child-support levy — broken down by the same visa categories and income bands Part 4 used; the comparison above is this series' own estimate, built from several separate official and semi-official sources, not a confirmed government figure.

If you've opened a Japanese bank account or signed a phone contract in the last few months — especially with a newly issued residence card — or if you work at a bank, MVNO, or payroll provider who wants to reach new arrivals before they hit one of the gaps above, get in touch. Specific, current answers to “what actually happened when I tried” are exactly what this series exists to collect and pass on.

This is Part 5 of India Japan Kaizen's Career Bridge Series, publishing weekly. Part 6 will look at enrolling in national health insurance and pension, and finding clinics and dentists used to treating patients who don't yet speak Japanese.
