Copiadd

Register your address once, and copy it whenever you need it — in Japanese, romaji, or kana (full-width/half-width), with or without a postal code, as a single line or field by field. Handy for opening accounts, applying for cards, online shopping, signing up for overseas services, and moving-related address updates.

Made for

• Writing the same address over and over for accounts and cards
• Forms that each demand a different format (full-width kana, half-width kana, romaji…)
• Ticking off each service one by one when you move

Features

• One-tap copy in many formats: Japanese / romaji / full-width kana / half-width kana, with or without a postal code, one line or by field.
• Auto-fill from a postal code: enter a postal code and the prefecture, city, kana, and romaji are filled in (bundled Japan Post data).
• Address-change checklist: link services to an address and mark each one done. Around 80 preset services included.
• Share & open: send via the OS share sheet, or open a change page in your browser.
