Your DBS, OCBC or UOB Visa or Mastercard works in Japan, and at covered stations of eleven rail operators in the Kanto region, including Tokyo Metro and Toei Subway, you can tap a contactless one at the ticket gate as you would on the MRT. GrabPay, PayNow and NETS are not on PayPay’s Alipay+ or HIVEX lists, and JNTO’s cashless-payments page does not name EZ-Link (checked 19 October 2026). OCBC Digital, ShopeePay and BigPay can pay at some PayPay shops. Singtel, StarHub, M1 and SIMBA all list Japan for roaming, and a Singapore driving licence needs an International Driving Permit from the Automobile Association of Singapore.

Paying: Singapore cards, multi-currency cards and wallets

DBS, OCBC and UOB cards

The Japan National Tourism Organization (JNTO) says international-brand credit, debit and prepaid cards are “generally accepted throughout the country”, and that Visa, JCB and Mastercard are the most widely accepted. JNTO adds that many rural places take only cash, and that cash can be withdrawn at Japan Post Bank and Seven Bank ATMs. More in Japan Cash vs Card.

The cost is set by your bank. DBS lists a foreign currency transaction fee of up to 3.25% on Visa, Mastercard and American Express cards: 1.00% from the card network and 2.25% from DBS. OCBC’s debit card fee sheet (version of 1 October 2025) gives the same 3.25% split. OCBC does not charge it only when the debit card is the default card linked to an OCBC Global Savings Account, you have allowed foreign-currency card transactions to be debited from that account, and it holds enough yen; otherwise the 3.25% applies. UOB’s fee page was not found on 19 October 2026; check your UOB card’s fee schedule.

GrabPay, PayNow, NETS and the wallets that do work

PayPay, a Japanese QR payment service, lets overseas QR wallets pay at its shops through two services, Alipay+ and HIVEX. PayPay’s merchant help page lists the apps it accepts through Alipay+. Three of them are used in Singapore: OCBC Digital, ShopeePay (Singapore and Thailand) and BigPay (Thailand, Malaysia and Singapore). With these, you scan the shop’s PayPay QR code and type the amount in yen. Each shop has to switch Alipay+ on separately, and vending machines that show a changing QR code are excluded.

GrabPay, PayNow and NETS are on neither PayPay list, checked on 19 October 2026, and no official page found says they pay at Japanese shops. Changi Pay appears in PayPay’s 3 October 2025 release and in the per-app guides on its Alipay+ payment-flow page, but not in the current list of linked services, so whether it pays in Japan is not confirmed. The full list of 35 wallets and the till steps are in Can You Use Alipay, GCash or Kakao Pay in Japan?

Tapping in: EZ-Link, SimplyGo and Japanese gates

No official source checked on 19 October 2026 lists EZ-Link stored-value cards, including SimplyGo EZ-Link cards, for Japanese ticket gates. A Visa or Mastercard you tap through SimplyGo is a bank card in Japan and works only where gates accept cards. JNTO’s cashless page names only IC cards that are part of Japan’s nationwide system, such as Suica and PASMO, which work “on trains, buses and at stores nationwide displaying this logo”. For the ticket machines JNTO describes, bring cash: buying and topping up there is cash only. Buying and using them is explained in How to Get and Use IC Cards in Japan.

On 25 March 2026, eleven rail operators in the Kanto region started a shared “Tap to Ride” service using contactless credit, debit and prepaid cards, and phones holding those cards, including Tokyo Metro, Toei Subway, Keio, Keikyu, Tokyu, Odakyu, Seibu and Tobu. Their 24 March 2026 release listed seven card brands (Visa, Mastercard, JCB, American Express, Diners Club, Discover and UnionPay) and 54 lines and 729 stations at launch, and adult fares only.

Use contactless payment only on the lines and stations listed in the release, subject to any gate restrictions it states; coverage is partial for some operators. Seibu, Tobu and Odakyu Hakone list some stations only, Sotetsu some automatic gates plus staffed counters, and boarding at Nakano is not covered. Check the tables before you travel. JR East is not one of the eleven; on JR lines that accept IC cards, use Suica or PASMO, and check coverage and ticket rules for other JR routes.

Grab: not confirmed as a ride app in Japan

On 8 July 2022, the Japanese taxi app GO announced that Grab users from Singapore, Malaysia and the Philippines could call GO taxis in Japan from the Grab app. GO’s English page, checked on 19 October 2026, does not mention Grab and no 2026 confirmation was found. Install Uber or GO before you land. More in Does Uber Work in Japan?

Phone and data: Singtel, StarHub, M1 and SIMBA

All four telcos list Japan on their roaming pages. SGD prices as shown on 19 October 2026. Some plans already include roaming data; check yours in the telco’s app before you fly.

Roaming keeps your Singapore number for bank one-time passwords; SIMBA says OTPs are received overseas at no extra charge. With a Japan eSIM for data, keep the Singapore line in the phone and check with your telco that SMS still arrives.

Plugs: Type G and 230 V meet Type A and 100 V

The IEC lists Singapore with Type C, G and M plugs at 230 V, and Japan with Type A and B at 100 V; JNTO says Japan’s voltage is “uniformly 100 volts”. Your three-blade plug does not fit: bring an adapter, which changes only the shape, and check each charger’s INPUT line for 100–240 V. More in Japan Plug Type and Voltage.

Japanese adapter boxes use their own plug letters, not IEC letters; compare the drawing on the box with your plug. Amazon links are affiliate links. As an Amazon Associate, Hidden Japan Gems earns from qualifying purchases.

Medicines from Singapore

Japan’s Ministry of Health, Labour and Welfare (MHLW) lets you bring medicines for your own use without paperwork up to these amounts: prescription drugs, up to one month’s supply; non-prescription medicines for external use, up to 24 per item; other medicines, up to two months’ supply. Above that, you need an Import Confirmation, applied for and received before you leave home.

Some ingredients need more. The Narcotics Control Department lists codeine as a narcotic, which needs permission before you enter Japan; substances with 1% or less codeine are excluded (controlled substances list dated 12 December 2024, the version linked from its page on 19 October 2026). Pseudoephedrine is listed as a stimulants’ raw material, which also needs advance permission; products with 10% or less are excluded. Amphetamine is prohibited for individual travellers even on prescription. If a cough mixture or cold tablet from your Singapore clinic contains either ingredient, ask for its strength before you pack it; if it is over the threshold or the strength is unknown, check the Narcotics Control Department’s current guidance and get any permit before you travel.

Driving: a Singapore licence needs an IDP

The National Police Agency’s list of international driving permit forms (as of June 2026) shows Singapore as a 1949 Geneva Convention party whose permit, issued by the Automobile Association of Singapore, is valid for driving in Japan. The Tokyo Metropolitan Police says the permit is valid for one year from the date of issue, and that you may drive with it for one year from your entry into Japan. You must be within both limits; whichever comes first ends its use.

AA Singapore charges $20 for the permit. Online orders add $7 courier and take 10 working days; walk-ins get it immediately. AA cannot issue one on a foreign licence. Road signs: Japanese Road Signs.

Tipping and halal food

JNTO: tipping is not common in bars, cafes, restaurants, taxis or hotels; a tip for a private guide goes in an envelope. Japan has no central halal accreditation body, and cooking sake and mirin are in many seasonings.
