## What is Eiju?

Eiju is a notebook for foreign residents preparing to apply for permanent residence in Japan.

"Have I been away too much?" "Do I have 5 years on a work status?" "Did I ever pay resident tax late?"
The application looks at exactly these things. Eiju works them out from your own records and shows them at a glance.

Start years before you apply, and build the record one trip, permit and payment at a time.

■ Try it with sample records first
A sample person with ten years of records lets you try every feature, Premium included. Open it from the first screen or Settings › Try with Sample Records. Nothing is saved and your own records are not touched.

■ Ready for the April 2027 changes
The permanent residence guideline revised on October 1, 2026 applies in full to applications from April 1, 2027. Enter your application date and Eiju uses the rules for that day (the spouse route, how a 3-year period of stay is treated, and more).

■ Days abroad, counted for you
- Total days abroad over the last 10 years, and your longest trip
- A warning before "6 months at once" or "2 years 6 months in total"
- Add a planned trip to see its effect before you book
- A chart by year, and CSV export

■ Years from your residence history
- Continuous years in Japan from the dates on your residence cards
- Years on a work or residence status (Technical Intern, Specified Skilled Worker (i) and others left out, as the guideline says)
- The years for spouses, long-term residents and highly skilled professionals (70 and 80 points)
- Whether your period of stay counts as the longest one

■ Taxes and insurance on time (Premium)
- Resident tax, National Pension and National Health Insurance, installment by installment
- Fill in a fiscal year's due dates at once, mark each one paid with a tap
- Late and unpaid installments in red, reminders 3 days before each due date

■ The official self-check and documents
- The questions of the Immigration Services Agency's self-check sheet, answered from your records where possible
- The new points of the revised guideline, such as Japanese ability and understanding everyday rules
- The document list for your route, with reminders before certificates turn 3 months old (Premium)

■ After you apply
Enter the filing day to see how long the review has taken against the standard 4 to 6 months, with a reminder that your current permit still needs renewing meanwhile.

■ A PDF of your records (Premium)
Residence history, trips, payments and self-check in one PDF, in Japanese or your app language, to take to a 行政書士 or the immigration counter.

■ Your family too (Premium)
Keep separate records for each family member applying with you.

■ Privacy
- No account, no ads
- Your records stay on your iPhone and in your iCloud; the developer cannot see them
- Lock with Face ID or passcode

■ Six languages
日本語, 简体中文, 繁體中文, English, 한국어, Tiếng Việt

■ Premium
- Yearly plan with a 1-week free trial, or a one-time lifetime purchase
- The yearly plan renews automatically. Cancel in App Store settings at least 24 hours before renewal

Note: Eiju is a reference tool for records and math. It does not decide whether permanent residence will be granted and does not prepare application documents. It is not affiliated with the Immigration Services Agency of Japan. Always check the official requirements and procedures with the Agency.
