About SimJapan.net
SimJapan.net is an independent information website created to help foreigners understand and compare useful services for living in Japan.
Moving to or living in Japan can make everyday tasks—such as choosing a SIM card, getting a Japanese phone number, finding portable WiFi, arranging home internet, or applying for a credit card—feel complicated. Service information is often presented mainly in Japanese, and requirements may be difficult to understand for newcomers.
Our goal is to make this information clearer and easier to follow.
