Tips for Finding High-Quality and Affordable eSIMs for Use in Japan

To find a good quality, low-cost eSIM that works in Japan, the key is to purchase from a Japanese company. There are over 50 services offering eSIMs for use in Japan, each with various plans, which might make it difficult to choose.

However, the criteria for finding a high-quality and affordable eSIM are simple: buy from a Japanese company.

If a company not operating in Japan offers eSIMs for use in Japan, you'll end up using roaming for communication. Primarily, China Mobile HK provides this function, but it relies on roaming with Japanese telecom companies. This means there are fees for both China Mobile HK and the Japanese telecom company, inevitably leading to higher communication costs. When communicating in Japan, purchasing an eSIM from a local Japanese company will be considerably cheaper. Understanding this will help you buy a cheap and good eSIM.
