Nowadays our planet has been largely globalized and people from different parts of this planet can communicate with each other easily and quickly through lots of modern tools.
The only problem left is language. If you need to understand each other, you should understand each other's languages. So many people choose to learn the Japanese language online, trying to supplement the gap between those within the nation and those outside it. Japanese today is already another target for people to focus on.

But let's discuss why we should do so? In spite of Japan's small territory, Japan is one of the most powerful nations around the world in terms of economy and politics. As we all know Japan's economy is so far the third place in the whole world after America and China. If you are electronic products lovers, you must know Sony; if you are interested in cars, you must know Honda and Toyota. Such brands are world-famous products.
Not only do common people appreciate their brands, but also people love their functions and abilities. You see, Japanese products are often highly sophisticated and always have a very long life to use for users.
Even though sometimes some big mistakes happen and make Japanese people ashamed of themselves, like Toyota's car paddle problem. But generally, people love to drive Japanese cars. This is one small element that you should learn Japanese.
Then I think culture always plays an important role in people's lives and it cannot be violently separated from language.
