Most foreigner-targeted housing companies provide internet as standard, whether as a line connection in your room/apartment, a shared wi-fi network or a portable wi-fi device. If you are renting independently or have specific requirements and want to have your own connection, there are a number of options available.

Connection Types

Fiber to the Home (FTTH)

Optical fiber transfers data at the rate of 10Mbps to 100Mbps so it is extremely fast. Sometimes, this service is limited in certain areas. Line construction work is necessary, so if you live in an apartment, you will need to get permission from the owner as well as the real estate agency.

Cable Television Line (CATV)

By using Cable TV, you may be able to use the same line to connect to the Internet. Please check with the cable company to see if the area in which you live has Internet via CATV capability.
