Globalization, the Internet and increased mobility have made the planet a smaller place. The world is now often referred to as a global community, and its lingua franca is undoubtedly English. It is the official language of air traffic control and the de facto language of both international business and, apparently, international terrorism. According to linguist David Graddol, one third of the world's population will soon be studying English.

The market for English lessons in Japan is huge, and the options facing would-be students here can be daunting. There are the ubiquitous "big four" chain schools — Nova, Aeon, Geos and ECC — that can be found near most decent-size train stations. There are a few medium-size chains, which market themselves as a more personal alternative to the major players. Finally, at the other end of the scale are the independently owned English schools, often run by expats who have decided to stay long-term in Japan.

There are alternatives to "eikaiwa" (English conversation, or English conversation schools) too. Many companies, especially foreign ones or Japanese firms with a strong overseas presence, provide English lessons on-site for their employees. Some people may choose to avoid the conversation-school route completely and take lessons with a private tutor. They can usually be found through specialized Web sites or classified ads, and the lessons generally take place in a coffee shop or in the student's home. For those who find themselves strapped for cash, there is always the option of doing a language exchange — teaching Japanese in return for being taught English.
