Currency Exchange (Yen / 円)As stated above, Exchanging at the airport is the best strategy, because bank branches at airports are open regardless of bank holidays. If you need to change from a foreign currency in town, go to a bank on a weekday between 9am and 3pm. Not all branches change currency, so you should find one which does, for example, at the airport. Banks don't work on bank holidays - obviously - Saturday, Sunday and national holidays. Check them at:
(It's not our site, but I find it useful.)
Exceptionally, bank branches at airports are almost always open.
Tap waterTap water in Japan is drinkable.
TippingTipping is never necessary in Japan. When you really want to, use banknotes, because tipping with coin can be rude.
Time ZoneJapanese time zone is GMT+9. In other words, when it is 10:00 in London, it is 19:00 in Tokyo. Japan has no summer time.
Electricity100V. Power plugs are almost compatible with U.S. plugs.
The frequency is 60Hz in western regions and 50Hz in eastern regions including Tokyo. This usually wouldn't be a problem, but if you are concerned, check the followging page for areas of frequencies:
Kansai Electric Power Co's official page about frequencies
TrafficCars and trains drive on the left. People are encouraged to walk on the right.
But there is one strange thing... In Tokyo area, people stand on the left on escalators, but in Western area of Japan, they stand on the right on escalators! We sometimes talk about where is the 'border' of this custom...but nobody around me seems to know. So if you found the border while traveling between the eastern and the western parts of Japan, let me know!!
Emergency Call110 - Police
119 - Amblulance
Public PhoneUse coins or 'telephone card' sold at convenience stores. Prices start from 500 yen.
ATMJapanese biggest banks don't seem to accept foreign cards. So where to go? Use Seven Bank ATMs, usually found at Seven-Eleven convenience stores! And this is why you will see Seven Bank ATMs at all airports in Tokyo.
Address NotationJapanese address system is not based on streets. Address are divided into blocks, sub-blocks, and so on.
Some major components of Japanese address system:
Prefecture (To, Do, Fu, Ken) - Tokyo-to, Hokkai-do, Kyoto-fu, Chiba-ken, etc.
District or Ward (Ku)
Town (Machi) / Village (Mura)
Block number within town (Chome)
Number inside Chome (Banchi)
Room number (Go)
EXAMPLE: the address of Tokyo Metropolitan Government on their website reads:
8-1 Nishi-Shinjuku 2-chome, Shinjuku-ku, Tokyo 163-8001
And here is how to decode it:
2-chome, (Block number)
163-8001 (Postal code)
Areas of TokyoTokyo consists of 23 Wards, 26 cities, 1 county, 2 towns and 7 villages on islands.
Probably you need to know only about some of the 23 wards.
Are there dialects in Japan?Japan has MANY dialects, some of which are hard to understand even for a Japanese. The most famous dialect is 'Osaka-ben' (dialect of Osaka prefecture). Dialects around Osaka, including 'Kyoto-ben' (dialect of Kyoto prefecture) are collectively known as 'Kansai dialect'.
WiFiWarning: If you see a sticker saying 'Free WiFi' at the front of a shop, look carefully. If it has an illustration of a white dog or a humanoid mushroom, it is free only for Japanese mobile contractors.
Here are some free WiFi spots:
- Beck's coffee shops at JR train stations
- Starbucks (but not at all shops)
- Convenience stores (Registration with you email is required and can be tricky.)
- Modern cafes/bars (but not all of them)
- Tokyo Metro and Toei Subway stations and trains

If you are staying for two week or less, buying a prepaid sim card at the airport might be a safe bet.
