There is no time difference between Japan and South Korea. Neither is daylight saving time observed, so the time in South Korea is the same as Japan throughout the year.



South Korea’s climate can be considered nearly identical to the northern to central regions of Honshu in Japan. There are four distinct seasons and a rainy season. Usually, visitors from Japan can wear the same type of clothing as they wore in Japan at the time of their departure. Winter is quite cold, so precautions against the cold must be taken. Generally, the disparity between cold and warm temperatures is more extreme than Japan.

Currency and Exchange Rate, Tax, Currency exchange, Tip

Currency and Exchange Rate

South Korean banknotes and coins

The unit of currency is the won, abbreviated as W. As of January, 2020, W100 is equal to approx. JPY9.44. There are four denominations of banknotes: W50000, W10000, W5000, and W1000. There are seven types of coins: W500, W100, W50, W10 (new and old), W5, and W1.


Consumption activities are subject to a 10% value added tax (VAT). Foreign tourists can receive a maximum 9% tax refund on purchases of at least W30,000 at stores with a TAX FREE symbol by completing a procedure. You cannot get a refund for accommodation fees at hotels or food and drink costs at restaurants that are not eligible for a tax refund.


Tipping is not required. A service charge is added in advance to expenses such as meal charges at upscale establishments and room fees at hotels. It is acceptable to tip when receiving a special or excessive service.

Voltage and plug


A 220V outlet

In South Korea, the voltage is 220V and outlets are mostly the same shape as Europe, type SE (that also fit type C plugs). In Japan, the voltage is 110V and outlets are type A, so a plug adapter or transformer is needed when using Japanese electronics there. Japanese electronics that are also compatible with 220V only require a plug adapter and not a transformer.

Video and DVD

Video and DVD

The DVD region code is 2 in Japan and 3 in South Korea. When buying DVDs, get ones that are region free (all region). DVDs cannot be played on store-bought DVD players with a different region code. The region code can be changed on computers, but usually only up to 5 times. For Blu-ray, both Japan and South Korea are region A, so Blu-rays bought in South Korea can be played normally in Japan.
