About Japan Harbor
Japan Harbor is a plain-English resource for the practical side of traveling in and living in Japan — tax-free shopping, money and taxes, and the paperwork. Our goal is to answer real questions with the actual numbers and the concrete steps, so you don’t have to piece it together from scratch.
How we research
- Official, primary sources. We rely on government ministries, tax and customs authorities, and other official bodies — not second-hand blog posts.
- Sources cited. Each figure and rule links to the official page we checked, with the date we checked it.
- Honest about change. Rules, amounts and deadlines change and can depend on your situation. We avoid false certainty and point you to the official body for the final word.
What this site can and can’t do
Japan Harbor helps you understand how things work and plan ahead. It does not provide individual legal, tax or immigration advice, and it can’t guarantee your specific case. Always confirm the details with the relevant official body — or a licensed professional — before you act.
How this is funded
Japan Harbor may earn from advertising or affiliate links (for example, money-transfer or eSIM services) to cover running costs. This never changes which facts we report, and we don’t require you to use any particular service.
Who runs this
Japan Harbor is operated and edited by Libra, a business based in Japan. For corrections or enquiries about our content, please use our contact form.
