Cambodia has a tropical monsoon climate, and its seasons are roughly divided into the dry season in the wet season. The seasons do not differ greatly between regions during the same period. The best season for traveling is the dry season from November to May, and the period from November to January is the most comfortable, with little rain.

Currency and Exchange Rate, Tax, Currency exchange, Tip

Currency and Exchange Rate

Banknotes feature portraits of the King, historical remains, monuments, and other pictures. Four types of coins (50, 100, 200, and 500 riel) are issued, but they are not in use.

The unit of currency is the Riel (denoted R on the website), and there is no subunit. 100R is approx. 2.6yen (as of March 10, 2020). There are over 20 different types of officially issued banknotes, but only 18 are actually distributed in the market: 50, 100 (2 types), 200, 500 (2 types), 1000 (3 types), 2000 (2 types*1 ), 5000 (2 types), 10,000 (2 types), 20,000, 50,000, and 100,000R. In addition, US dollars can be used normally as currency in Cambodia. However, cents that are the subunit of US dollars are not used.* A new 2000 riel banknote has also been issued, but it is not shown in the photo.


Basically, a 10% value added tax (VAT) is imposed, but in reality it is usually not imposed on shopping and payments at the tourist level. Travelers pay VAT at mid/high class hotels and upscale restaurants or when shopping at a supermarket or other place where a receipt is issued at the cash register. There is no VAT refund system in Cambodia.


Tipping is generally not required as there is no custom for tipping in Cambodia.

  • Restaurants: Not required in restaurants other than upscale restaurants. Even in upscale restaurants, it is unnecessary when a service charge is added.
  • Hotels: Tip bellhops and room service approx. 2000 to 4000 R.
  • Taxies: Not necessary.
  • Motorbike taxis, tuk-tuks: Not necessary.
  • Guides: Approx. 1 to 3 USD a day.
  • Hired drivers: Approx. 1 to 3 USD a day.

Voltage and plug


A type A, type C, and type SE adapter
Socket types differ among regions, hotels, and guest rooms

220V and 50Hz. Many plugs are a combination of Type A and Type C. There are Type A, Type C, and in rare instances, Type SE plugs. A transformer is needed to use 100V electrical equipment from Japan. Some high class hotels will lend you a transformer.

Video and DVD

Video and DVD


Cambodia generally uses PAL, but secondhand equipment is often imported from overseas, so many TVs and video players are compatible with multiple systems including NTSC that is used in Japan and the US and SECAM. However, it is becoming increasingly difficult to get video players as VCDs and DVDs become more commonplace.


VCDs were most common up until several years ago, but now DVDs are mainstream. Note that there are many illegal copies in distribution. Do not forget to check the region code when making your purchase. The region code is 2 in Japan and 3 in Cambodia, so you can only watch DVDs in Japan that are labeled "All code". Note that even regular DVDs with an official government seal are often actually copies and some products have region codes for the US or other countries.



Though post office business hours differ slightly for each post office, they are usually open from 7:00 to 18:00 and many are open on Sundays too.

Postal fees

Airmail to Japan costs 3000 R from Siem Reap and 2000 R from Phnom Penh for a postcard, and 2700 R up to 20 g, 4800 R up to 50 g, 8200 R up to 100 g, and 15900 R up to 200 g for sealed letters. Small packages are about 7.5 USD up to 0.5 kg and 15 USD up to 1 kg by air.

Age Limit

Tobacco and alcohol is restricted to persons 18 years old and older in Cambodia. A driver's license is required for driving cars or 49 cc or higher motorcycles (same for foreigners). Helmets and rear-view mirrors are mandatory when driving motorcycles. Cambodia is a member of the Vienna Convention; according to international law, you can drive in Cambodia with an international driver's license without the need to switch to a Cambodian driver's license. However, many general police officers do not know about international driver's licenses, and you may be fined if subject to an inspection. Motorcycle accidents by foreign tourists are very common, and great caution is a must when driving.


Avoid topics related to politics or war. When visiting a temple, do not wear shorts or short skirts, and remove your footwear when entering the temple hall. Always show respect for the Buddhist monks. Women are not allowed to touch monks or hand them objects directly. As there are thought to be spirits above everyone's heads, you should avoid touching someone else's head or patting the children on the head.
