About This Site

Japan Travel Dobbo (travel.dobbo.jp) is an English-language information site, written and checked in Tokyo, about mobile data in Japan for travellers: eSIM plans, pocket Wi-Fi and connectivity guides. We do not sell anything ourselves and we are not a party to any contract you enter. We are not a mobile carrier or eSIM provider and we do not sell, activate or support any plan ourselves. When you buy or sign up, you deal directly with the provider under that provider’s terms.

How we work

We read the Japanese primary sources (government publications, laws, providers’ official pages) and turn what they actually say into decisions you can act on. Every figure carries the date it was checked. Some links are affiliate links; they never change the order or the facts. If a provider’s page disagrees with ours, the provider’s page wins. The details are in our Editorial & Advertising Policy. How we handle personal data is in the Privacy Policy, and the rules for using the site are in the Terms of Use.

Legal notices and rights claims

Legal notices about our content, and claims about copyright, trademark, image rights or defamation, should be sent through the contact form with the subject “Rights claim / legal notice”. Please include the page URL, the passage concerned, the right you rely on and how to reach you. If a notice must be served in writing, we will give you a postal address.
