How much does it cost to request family registers myself?

The fees for family register (koseki) documents are as follows, per copy (as of September 2026; the amounts are the same in almost all municipalities).

• Certified copy of the family register (certificate of all matters): ¥450
• Certified copy of a closed register (joseki) / pre-revision register (kaisei genkoseki): ¥750

If you request them by mail, the issuing fee for fixed-amount postal money orders (¥200 each) and postage both ways are added. The number of documents ranges from a dozen or so to more than thirty depending on the family, and the total generally comes to around ¥10,000 to ¥20,000-something per lineage.
