Terms of Use

These Terms of Use (“Terms”) are an agreement between you and Japan Travel Dobbo editorial team (“we”, “us”), the publisher of Japan Travel Dobbo (“this site”). They are standard terms within the meaning of the Japanese Civil Code. By viewing or using this site you accept them. If you do not accept them, please do not use the site.

1. Scope

  1. These Terms apply to every page and feature of this site: articles, comparison tables, calculators, AI tools, the contact form and the email list.
  2. Our Privacy Policy and Editorial & Advertising Policy form part of these Terms.
  3. If you are under 18, use this site only with a parent’s or guardian’s consent.

2. What this site is

  1. This site provides general information about mobile data in Japan for travellers: eSIM plans, pocket Wi-Fi and connectivity guides. We are not a mobile carrier or eSIM provider and we do not sell, activate or support any plan ourselves.
  2. Any purchase, sign-up, contract, cancellation or refund is between you and the provider, under the provider’s terms. We are not a party to it and not an intermediary.
  3. Nothing on this site is legal, tax, immigration, financial, medical or other professional advice for your particular situation. Where your decision depends on your circumstances, consult a licensed professional.
  4. Plan prices, data allowances, network partners and activation rules are those published by each provider on the date shown and change often. Your purchase is a contract with the provider under the provider’s terms.
  5. Whether an eSIM works depends on your phone, carrier lock and the provider’s network. We cannot guarantee coverage, speed or compatibility for your device.

3. Accuracy

  1. We build our content from Japanese government sources and providers’ official pages and check figures carefully, but we do not warrant that any content is accurate, complete, current, useful or fit for a particular purpose.
  2. Prices, terms, availability and conditions in Japan change often. If a provider’s official page disagrees with ours, the provider’s page prevails. Always confirm current terms with the provider before you decide.
  3. Decisions you make on the basis of this site are your own responsibility.

4. Advertising and affiliate links

  1. This site contains affiliate links. If you buy or sign up through one, we may receive a commission from the provider or an affiliate network. The price you pay does not change. This disclosure is made to satisfy the US FTC endorsement guides and Japan’s rules on undisclosed advertising.
  2. How commissions do and do not affect our content is explained in the Editorial & Advertising Policy.
  3. Third-party sites, and the products and services of advertisers, are the responsibility of those third parties. We are not responsible for their content, quality, safety, legality, contract terms or data handling, or for any transaction you enter with them.

5. Intellectual property, linking and quotation

  1. All text, images, tables, data, code, design, logos and characters on this site (“Content”) belong to us or to the rights holders credited. These Terms do not transfer or license any of those rights to you.
  2. You may link to any page of this site, commercially or not, without asking. Please do not frame our pages inside your own site or hot-link to our images or files.
  3. Short quotations with attribution (our site name and the page URL), where the quotation is incidental to your own work and unaltered, are welcome. Any other reproduction, republication, translation, distribution of summaries or sale of Content requires our prior written permission.
  4. Collecting Content by automated means (crawlers, scrapers, bots), and using Content to train generative AI or to build a competing site or database, is prohibited unless we have expressly permitted it. Ordinary indexing by search engines is permitted.

6. Prohibited conduct

You must not:

  1. break the law or public order, or use the site in connection with a crime;
  2. infringe the copyright, trademark, image rights, privacy, reputation or other rights of us or anyone else;
  3. overload our servers or network, access the site by automated means at volume, attempt unauthorised access or probe for vulnerabilities;
  4. reproduce, collect or use Content in a way section 5 prohibits;
  5. submit false information or someone else’s information through the contact form, AI tools or email list, submit in bulk, or use them for marketing or solicitation (advertising enquiries excepted);
  6. impersonate us or the site, or use our name, logos or characters without permission;
  7. interfere with the operation of the site, or do anything else we reasonably consider inappropriate.

7. Consequences of a breach

  1. If you breach, or we reasonably believe you are about to breach, these Terms, we may without notice block or limit your access, delete what you submitted, suspend features, report you to the relevant hosting provider, platform or affiliate network, and take legal action.
  2. You are liable for loss we suffer as a result of your breach, including the cost of investigation, response and legal fees.

8. Third-party material and quotations

  1. This site has no feature that lets visitors post or publish content. Reviews and opinions that appear in articles are quoted or summarised by us with their source stated.
  2. If you hold rights in something we have quoted or shown and object to its use, tell us through the contact form with the subject “Rights claim / legal notice”. We will review it and correct, remove or add attribution as appropriate.
  3. Should we add a posting feature in future, we will handle claims under Japan’s Information Distribution Platform Act (formerly the Provider Liability Limitation Act).

9. Changes to, suspension or closure of the site

We may change the content, features or design of the site, add, edit or remove pages, suspend the site for maintenance or because of a fault, or close it, at any time without notice. Our responsibility for any resulting disadvantage is limited as set out in section 10.

10. Limitation of liability

  1. Except where loss results from our wilful misconduct or gross negligence, we are not liable for any loss arising from your use of this site or inability to use it, from errors, omissions or outdated information in our content, from third-party sites or transactions, from the output of AI tools or calculators, or from unauthorised access to or alteration of the site by third parties.
  2. Where we are liable for ordinary negligence, our liability is limited to direct and ordinary loss actually suffered, and capped at JPY 10,000 in total. We are not liable for lost profits, indirect, consequential or special loss.
  3. Nothing in this section limits liability that cannot be limited under applicable law, including the Japanese Consumer Contract Act and any mandatory consumer protection law of the country where you live. In those cases this section applies to the fullest extent the law allows.
  4. If you notify us of an error, an infringement or outdated information, we will review it within a reasonable time and correct or remove it as needed. Where we respond appropriately to a notice, our liability for loss said to arise from the content before the notice remains limited as in paragraphs 1 and 2.

11. Contact and notices

  1. Contact us through the contact form. We do not undertake to reply to every message and may decline to reply. We do not take phone calls.
  2. Legal claims, notices and rights claims must be sent through the contact form with the subject “Rights claim / legal notice”. Where a written notice is required, we will provide a postal address. A notice sent any other way may be treated as not received.

12. Changes to these Terms

  1. Under Article 548-4 of the Japanese Civil Code we may change these Terms without your individual consent where the change is in the general interest of users, or where it is reasonable in light of the need for the change, the appropriateness of the new terms and other circumstances.
  2. Before a change takes effect we will set an effective date and announce on this site that the Terms are changing, what the new Terms say and when they take effect. Using the site on or after that date is acceptance of the new Terms.

13. Severability

If any provision of these Terms, or part of one, is held invalid or unenforceable, the rest of that provision and all other provisions remain in force. The invalid part is to be read in the way that comes closest to its original purpose and is permitted by law.

14. Governing law and jurisdiction

  1. These Terms and your use of this site are governed by the laws of Japan.
  2. Any dispute between you and us about this site is subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance, to the extent mandatory law where you live does not provide otherwise.
