Learning a foreign language always has it's significance , but Japanese is special , as japan has a declining population but increase in human resource . Learning japanese will help both the students and experienced professionals with its numerous job opportunities . You can simply search the internet for the demand for bilingual professionals in the internet/job portals plus the visa processing is very simple and easy (unlike US visa processing) . The pay/CTC of employees are on par or above US markets. I am attaching few japanese ebooks that might be highly useful to learn the language.
