Most Japan guides are written for visitors from the US or Europe. If you are coming from Vietnam, the things that matter most are the visa, cash, and the cold. Here are eight to sort out early.

1. Sort out the visa first

Vietnamese passport holders typically need a visa for Japan. The process takes time, so start early. Rules change, so rely on official Japanese embassy or consulate information rather than any guide.

2. Your plug often fits — check the voltage

Many Vietnamese sockets accept flat pins, so chargers often fit Japanese sockets. Voltage is 100V against 220V. Phone and laptop chargers usually handle 100–240V; check single-voltage items like hair dryers.

3. Your local transit card will not work

Use Suica, PASMO, or ICOCA, which work across most of Japan. See our IC card guide or set up Suica on iPhone.

4. Pack for real cold

Winter is properly cold, and even spring and autumn evenings can be chilly. Bring layers and a warm coat, and check the forecast for your dates.

5. Cash still matters

Cards are common in cities, but small restaurants and shrines are often cash-only. Carry yen and read our cash versus card guide.

6. Trains are quiet and exact

Phone calls on trains are rude, conversations stay low, and trains run to the minute. Tipping is not expected. See how not to cause trouble in Japan.

7. Eating while walking and bins

Eating while walking is generally discouraged, and public bins are scarce. Eat near the stall and carry a small bag for rubbish.

8. Tap water is safe

Tap water is safe to drink across Japan, so bring a bottle and refill it.

Where to go next

Choosing a base? Read Kyoto or Osaka. For data, compare eSIMs.

Do Vietnamese travellers need a visa for Japan?

Typically yes. Confirm the current process with the official Japanese embassy or consulate.

Can I use my Vietnamese transit card in Japan?

No. Use Suica, PASMO, or ICOCA.

Is tap water safe in Japan?

Yes. Tap water is safe to drink across Japan.
