Language Learning Immersion at Home

We learn languages best in the country where that language was spoken. You would learn English more effectively in the UK or USA and I should learn Japanese more effectively in Japan. Immersion is a good strategy, but is it possible to do at home? It is impossible for many people and many of you listening right now to move to an English speaking country and fully immerse yourselves in the language. But don't worry, it is possible to achieve some level of immersion at home in your own country.
