Japan vs Taiwan: 10 Things That Work Differently (2026)

Almost every English-language Japan guide is written for someone flying in from New York, London, or Sydney. That reader needs a plug adapter, needs to be told that nobody tips, and needs a paragraph explaining what a convenience store is. If you are travelling from Taiwan, none of that is news — and some of it is simply wrong for you.

Taiwan and Japan feel close. The convenience stores share names, the train systems look similar, and the food culture overlaps enough that nothing seems foreign. That closeness is exactly what causes problems: the things that differ are small, specific, and easy to assume away. Here are the ten that actually matter.

1. Your chargers work — you do not need an adapter

Taiwan runs on 110V and Japan runs on 100V, and both use the same flat two-pin Type A plug. Your phone charger, laptop brick, and camera battery charger all work in Japan with nothing attached. This is the single biggest piece of generic advice you should ignore: guides tell travellers to buy an adapter because they are written for visitors from countries with different plugs.

The only thing worth knowing is that high-draw appliances — hair dryers, curling irons — run slightly weaker on Japan's lower voltage, and may take longer to heat up. Hotels supply hair dryers anyway, so this rarely matters in practice.

2. Your EasyCard does not work in Japan

EasyCard (悠遊卡) and iPass (一卡通) are Taiwan-only. They will not tap through a gate in Tokyo, Osaka, or anywhere else in Japan. You need a Japanese IC card instead — Suica, PASMO, or ICOCA, depending on which region issues it.

The good news is that Japanese IC cards work across most of the country regardless of which one you hold, so you do not need a different card for each city. Our Japan IC card guide covers the differences and where to get one.

3. Your payment apps stop at the border

LINE Pay and 街口支付 are part of daily life in Taiwan, and LINE itself is just as dominant in Japan — which makes it easy to assume the payment side carries over. Do not plan around it. Japanese QR payment runs on separate domestic services, cross-border arrangements between them have changed repeatedly, and anything that did work one year has a habit of quietly not working the next.

Plan on a credit card plus some cash. Japan has moved toward cards faster than its reputation suggests, but small restaurants, older shops, and shrines are still cash-only more often than their Taiwanese equivalents. Our guides on cash versus card in Japan and which ATMs accept foreign cards cover the practical side.

4. Stand on the correct side of the escalator

In Taipei you stand on the right. In Tokyo you stand on the left. In Osaka you stand on the right — the same as Taipei. This catches out even frequent visitors, because the habit is automatic and the switch happens when you change cities, not when you change countries.

The Osaka-versus-Tokyo split is one of those things Japanese people argue about too; the most commonly repeated explanation traces Osaka's habit to the 1970 World Expo, though it is closer to folklore than documented history.

5. Eating while walking is not a thing here

Taiwan's night market culture is built around walking with food in your hand. Japan's is not. At most food streets you are expected to eat standing near the stall where you bought it, then dispose of the packaging there. In some tourist areas it is now formally discouraged with signs.

6. Konbini look identical and are not

7-Eleven and FamilyMart exist in both countries, which is precisely the trap. Japanese konbini carry a different product mix, rotate fresh food far more aggressively, and act as service counters: you can post luggage, buy concert tickets, pay bills, and — at 7-Eleven — use an ATM that reliably accepts foreign cards.

What you will miss: the Taiwanese tea eggs, the wider hot-food counter, and the habit of customising your drink. We compared the three chains in detail in our Japanese convenience store comparison.

7. There is no 手搖飲 culture — and no customisation

Ordering 微糖少冰 is second nature in Taiwan. In Japan, drinks arrive as the manufacturer made them. Bubble tea exists and has had several booms, but it is a trend product rather than daily infrastructure, and sweetness and ice levels are generally not adjustable.

What Japan has instead is vending machines — roughly one on every block, stocked seasonally, switching to hot bottles in winter. It is the closest equivalent to the corner drink shop you are used to.

8. Taxis are expensive and scooters do not exist

In Taiwan a taxi is a casual choice; in Japan it is a considered one, and short trips can cost several times what you would expect at home. Scooters, the default way to move around a Taiwanese city, are not a realistic option for visitors either.

Build your plan around trains instead. It is genuinely faster in the major cities, and the rail network reaches further than most first-time visitors assume.

9. Onsen have rules you are expected to already know

Hot springs are a bigger part of travel in Japan than in Taiwan, and they come with etiquette that nobody explains on site: wash thoroughly before entering, no swimwear, no towel in the water, and tattoos are still refused at many traditional facilities.

None of it is difficult once you know it, and getting it right changes how you are treated. Our onsen etiquette guide walks through the whole sequence.

10. Entry is easy — but do the paperwork before you fly

Taiwanese passport holders travel to Japan visa-free for short stays, which is why the trip feels so casual. What has changed in recent years is the digital side: immigration and customs declarations are handled through Japan's official online system, and registering before departure saves a meaningful amount of time at the airport.

Where to go with this

If you are still deciding on a base, Kyoto or Osaka is the decision that shapes a Kansai trip most. For a day trip out of Tokyo, Hakone versus Nikko is the comparison worth reading first. And if you are shopping seriously, luggage forwarding solves the problem of carrying it all between cities.
