Sim cards and adaptors
 

Hi, we are flying in to Tokyo this Saturday - very excited! We are spending 3 weeks in Japan and most things are planned so just a couple of questions:-
1) Where is the most reasonable place to get a sim card in Tokyo for our unlocked mobile - I think we may need it for
data only;
2) Do we need an adaptor to charge our mobiles etc?
Thanks in advance for all help.

Most cell phone chargers are universal voltage - but to see for sure if yours is, check the charger's nameplate. If it says Input Voltage: 85-250V or something like that, you're fine.

Japan's voltage is 100V, so if that is in the range of your charger's specifications, then you're fine. Otherwise, you will need a transformer.

Khtodd - She asked about adapters, not converters.

The answer is that no, you do not need an adapter. Japan's outlets are compatible with US plugs.

Sorry BigRuss - I misunderstood. Working in the voltage changing industry, I assumed that she (I'm assuming 'she' from the user name) was wondering if she needed voltage change, since I talk to many people every day who mistakenly interchange the words adapter, converter and transformer, even though, technically, they are not interchangeable.

The OP also didn't specify where she was coming from, so it's hard to know if she needs a plug adapter without knowing her origin. You are correct, Japan has similar outlet configurations as the US, as long as you don't need grounding (which you wouldn't for cell phone chargers). It is more complicated if you have a grounding plug since Japan has 3 different kinds of outlets, which are not standardized by region, city or sometimes even building!

Thanks all for your replies - we are taking a universal adaptor for the plugs, hope that works, we are coming from the UK.

If the universal adaptor has US plugs, it will work.

The flip side is you need to make sure your electronics are dual voltage (which they probably are), so that they can handle the 100v AC power in Japan.

The best place to buy a Sim card with data is in one of the camera stores. They are much more expensive at the airport. I just bought a card with !G data for $25. Since Wifi is very prevalent one doesn't need much more.

You will be landing to sunshine.
