Deciding to relocate to Japan is a big challenge. There is a big culture shift from the West, both in terms of personal and professional life, and the language is notoriously tricky to pick up. Therefore, with so many things to worry about, attempting to land a job with a stable and established company is a good place to start.

Luckily, in terms of revenue, Japan is home to some of the largest companies — not just in Asia, but in the world. While some of them may be unfamiliar, many are household names, with their products and services a firm fixture on our high streets and beyond.

According to ForbesGlobal 2000 list, these are the top 10 biggest companies in Japan.
