Japan Digital Nomad Visa Insurance: What the Embassy Actually Wants to See

Insurance tripped up both of my Digital Nomad visa applications. The first was refused partly over it. The second had a great policy and still got an email from the embassy asking for more. Having insurance isn't the hard part. Proving it, on paper, in the way the embassy checks it, is.
The exact requirement
The Immigration Services Agency's Q&A says your private insurance must cover your stay in Japan for:
- Injury and illness, with medical treatment coverage of at least ¥10 million
- Death, either transport of the body home or a death benefit (no minimum amount is set)
- The whole stay, from the day you arrive to the day you leave
Digital nomads can't join Japan's National Health Insurance, so this policy is your health cover too.
Why good policies still get questioned
Plenty of nomad insurance plans easily meet the requirement and still cause problems, because the paperwork doesn't say it in a way a reviewer can confirm in 30 seconds:
- The certificate lists a policy number and dates, but not the coverage amounts.
- Death cover or repatriation of remains is buried in a long policy booklet, or not mentioned.
- Japan isn't named; the policy only says "worldwide."
- The limit is in euros or dollars, with no yen equivalent.
- It's a monthly subscription, so the certificate only shows the first month.
My first insurer's visa letter was a fixed template, with limits in US dollars and a note about Schengen requirements. They told me it couldn't be changed for Japan. For the second application I switched insurers, attached a certificate and well over a hundred pages of policy documents, and the embassy still emailed asking for proof of coverage for death, injury and illness in Japan, with the medical limit of ¥10 million or more.
Start with the official ISA form
The Immigration Services Agency publishes a reference form for explaining your private medical insurance coverage (民間医療保険の補償内容に係る説明書) on its Digital Nomad page. It lists it next to the insurance certificate and policy terms. Filling it in from your policy answers every requirement in one place. Check whether your embassy's checklist asks for it.
Have a one-page insurer letter ready
What finally worked for me was a short, signed letter from the insurer, addressed to the embassy. A good one states, in plain words:
- Your name, date of birth and policy number
- A policy period covering your whole stay
- That coverage includes the entire territory of Japan
- Medical cover for injury and illness, with the limit stated in yen
- Death cover, such as repatriation of remains
- A named person's signature or an official stamp
Ask your insurer for it before you submit, not after the embassy asks. When I forwarded the embassy's exact request, word for word, my insurer issued the letter that same afternoon, and the visa was approved that day.
Tips before you buy
- Ask first: "Will you issue a confirmation letter for Japan's Digital Nomad visa?" A quick yes is a great sign.
- Make sure the policy starts before you enter Japan and runs until after you leave.
- If it's billed monthly, get written confirmation it will run for the whole period.
- Check waiting periods if you're already abroad when coverage starts.
