  • Matters of Voltage:

    Regarding electronic equipment that you may be bringing with you: the voltage throughout Japan is 100V, which is different from North America (110V), Central Europe (220V), and most other regions of the world. I have been told that North American equipment will work fine in Japan without an adapter and vice versa; however, if you are bringing expensive or otherwise precious equipment, I urge you to check with the manufacturer or otherwise use caution before plugging it in! Finally, it may be a good idea to pack an adaptor for the plug (some Japanese power outlets do not have three prongs).

  • Internet access:

    We will arrange for wireless internet access available at the conference centre. Both the OCU Guest House and the KKC have internet connections available. At the KKC, you will need to bring your own LAN cable, although there are a small number of LAN cables that can be borrowed from the KKC front desk on a first-come, first-serve basis.

  • Cellphones:

    It is my understanding that most cell phone plans from other countries are not likely to work in Japan, but please check with your service provider to be sure. You may also rent a cellphone at the airport for a fee of usually about 500 JPY per day. However, please read the section "Culture" regarding the etiquette of cellphone use in Japan (in particular, it is considered rude to talk on the cellphone on public transportation!).

  • Public telephones (for domestic calls):

    There are several types of payphones in Japan, with different systems and (mutually incompatible) cards, unfortunately. However, the ones that are most standard (and these are for domestic calls only) are the light-green ones, which all accept a standardized thin ``telephone card" (pronounced ``terehon kaado'') which you can purchase at any convenience store or train-station convenience kiosk in various amounts (e.g. 1000 JPY). (The telephone cards most often sold at convenience stores, etc, ARE the ones accepted at the light-green payphones.) When you insert the card into the appropriate slot, the phone will display how many ``points'' you have left on your card, and as you make a phone call, the display will continually update to let you know how many points you have left.

    There are public telephones on certain cars in the Shinkansen bullet trains; these usually have English instructions posted nearby. There are also public telephones in the lobby of the Kansai Kenshu Centre.

  • International telephone calls:

    There are grey payphones, a little bigger/taller in size than the standard light-green payphones, from which you can make international telephone calls. These are much harder to find.

    MY PERSONAL SUGGESTION: Make all international phone calls at the Kansai Kenshu Centre or OCU Guest House, either from the KKC ground-floor lobby area (where there are both vending machines for international prepaid telephone cards AND international pay phones), or from your own room at the KKC or Osaka City University Guest House. For more details, please see the relevant sections in the ``Kansai Kenshu Centre'' or ``OCU Guest House'' sections of this website, below.
