There are more than 128 million speakers of Japanese in the world. Mastering the language can be beneficial considering the economic strength of Japan that employs millions of expatriates from across the world.

3. Korean

Arabic is the most difficult language to learn in the world. It is widely spoken in the Middle East and North Africa region, and is native to an estimated 110 million people.
