The biggest advantage to study in Japan is when a student goes to Japan and studies Japanese language, he gets twice faster growth in terms of Japanese language and culture knowledge compared to studying Japanese in India or in any other country through textbooks. It is always seen that the student becomes fluent in spoken Japanese within one month after landing in Japan because he is conversing everything in Japanese, first in basic and then very soon in native tone and speed because it automatically starts copy past work while speaking in their language with them.
Is it difficult to learn Japanese or is it easy? The answer is that it is both difficult and easy. Japanese pronunciation is rather easy. Japanese consists of 46 syllables that can only be pronounced in one way. Almost all of those syllables exist in English and other European languages so you can master the pronunciation rather quickly and people will often understand you when you read Romanized written in our alphabet. Japanese also use thousands of English loan words, “Gairaigo”, that has been adapted to Japanese pronunciation. Once you master these you will have immediately have access to a huge vocabulary.
The challenge when learning Japanese was the writing part when computers were not very common, but now this problem has already minimized drastically as it is very easy to type Japanese if someone has mastered spoken language and is able to read Kanji. Written Japanese consists of three writing languages. Hiragana and Katakana has one character per syllable where Katakana is only used for loan words. Those two writing languages are quite easy to learn but Kanji, consisting of a couple of thousand Chinese characters is much more challenging.
At Japanese language schools you can study Japanese from beginner level to advanced level. However many schools ask that beginners have at least knowledge of Hiragana and Katakana when you start a long term course in Japan. Japanese embassy too asks for N5 level cleared to issue COE. You can learn those on your own by for example memorizing one character per day. Only 6-8 months language training in India is enough to clear N5.
