NTTDoCoMo has the largest network coverage, and almost all of the prepaid SIM card services in Japan are based on their network.
NTTDoCoMo's 3G (the third generation) network is called FOMA, Freedom of Mobile Multimedia Access.
FOMA uses the 800 MHz band in rural areas while it uses the 2100 MHz band in metropolitan areas (1700 MHz band in a few areas).
However, the 800 and 1700 MHz bands are exclusively assigned to Japan.
So, if you have the 3G network with the 2100 MHz alone, you practically can connect to the internet only in major cities.
NTTDoCoMo also offers 4G (LTE) network under the service name of Xi, having a wide range of frequency bands: 700, 800, 1500, 1800 and 2100 MHz.
Some of the frequency bands are also used in countries other than Japan, however, the 1800 MHz, one of the most usual bands in the world, is available only in the following major cities: Nagoya, Tokyo, and Osaka.
As you have seen above, a usable frequency can vary from place to place, so, its highly recommended to check which band do you need for the area you want to go and which band is your device compatible with before you actually visit Japan.
Also, you have to make sure that your device must be unlocked (sim lock free)
and must support one of the following frequencies:
|4G[LTE]||Band 1(2100MHz), Band 19 (800MHz), Band 21 (1500MHz), Band 3 (1800MHz, limited to the Toumeihan area).||3G[W-CDMA/HSPA (FOMA)]|| Band 1(2100MHz), Band 19 (800MHz).
