Japan Address Generator
Choose a supported location, generate an example, and copy an address or individual fields. Names and streets are synthetic; delivery is not verified.
1870 sourced locality examples. Filters stay in this page's URL. Postal codes describe selected source locations, not every address in a city.
Population coverage estimate: 99.30% (2020 baseline), across 1,865 supported units. Counted population: 125,260,374 of 126,146,099. This measures population in supported municipalities or districts, not coverage of every postal code, street or building. 2020 census municipalities and wards are joined by JIS code to current Japan Post examples; unmatched boundary changes are excluded.

Address tools for Japan
The homepage previews countries and regions. This page opens directly with Japan selected, keeps its address fields together, and explains the local format and actual sample coverage, with region and locality filters.
Local format, cities and regions
Tokyo, Osaka and Kyoto are starting points for prefecture and locality selection. Japanese postcodes use seven digits, commonly shown as 123-4567.
Tokyo wards, Osaka wards and Kyoto wards should stay paired with their prefecture. Universities and landmarks explain place names but their real street addresses are never emitted here.
Japan address structure
Japanese addresses commonly use chome, block and building numbers rather than a street-name-only pattern. The synthetic line here demonstrates number groups; locality and prefecture are displayed separately with the seven-digit postcode. The mixed Japanese sample label and romanized place names are for form testing, not a verified native mailing label.

University address context
Kyoto University's official contact page uses Yoshida-honmachi, Sakyo-ku, Kyoto and the institutional postcode 606-8501. It demonstrates ward and locality detail; that campus postcode is not part of the generated Kyoto sample.

Use the sample correctly
Choose a supported sample above to open its local filters directly. Keep the selected locality, region and postal code together when filling a form. For CSV imports, set the postal column to text before opening the file so leading zeroes and letters survive spreadsheet conversion.
Use these examples for form layouts, software tests and demonstrations. Copy address excludes the name and phone; Copy full profile includes them. Missing region or postcode fields remain empty rather than invented. International phones may be assigned; their location and reachability are not checked.

Japan address generator FAQs
How do I generate a random Japan address?
Choose a supported region, locality or district on this page and select Random. Copy address returns the address fields; Copy full profile also includes the name and phone number. The Japan selection stays active as you generate new examples.
Which Japan cities or districts can I select?
This page provides 1,870 locality examples, including Chiyoda, Chiyoda Ku, Shincho, Shimogyo Ku, Kyoto Shi, Umeda, Kita Ku, Osaka Shi, Hakataeki Mae, Hakata Ku, Fukuoka Shi, Kita1-Jonishi(1-19-Chome), Chuo Ku, Sapporo Shi. Search for a locality, region or postal value and use the supported-samples list to open a location directly. The list describes current coverage rather than every city or street.
How should I format a Japan address?
Tokyo, Osaka and Kyoto are starting points for prefecture and locality selection. Japanese postcodes use seven digits, commonly shown as 123-4567. Use Copy address to keep the generated field order, or copy individual fields into separate form inputs. The postal reference linked below provides further addressing guidance.
Can I generate a Japan address with a postal or ZIP code?
Yes. Select a supported locality and its postal code. Current source examples include 100-0001, 600-8001, 530-0001. Preserve spaces, letters, hyphens and leading zeroes when present. The selected code describes a source location; it is not a lookup for every street in the city.
Does the Japan address generator include names and phone numbers?
Yes. Full profiles include a generated name and a phone example using +81. Use Copy individual fields when you need just the phone or locality. Phone examples support form-format testing; they do not confirm a person's identity or phone reachability.
Can I bulk generate Japan addresses in CSV or JSON?
Yes. In Batch address generator, choose 1–1,000 records and generate using the current region, locality and postal filters. Export CSV, JSON, SQL or plain text. More records vary the generated fields without adding locations to the Japan catalog.
Can I save my location filters and repeat a batch?
The region, locality and postal filters are stored in the page URL. Save that URL to reopen the selection. For repeatable batch output, retain the batch seed, record count, filters and data version; the exported provenance records the generation details.
Can I use Japan university or landmark addresses?
This generator creates example profiles for software tests and mockups. Universities and landmarks mentioned in the page explain local geography; they are not automatically inserted as residential addresses. For a specific institution, use its official contact page.
How do I keep local characters and postal codes when exporting?
Use a UTF-8-aware CSV importer and set postal-code columns to Text. This preserves local names and avoids dropping leading zeroes. JSON also keeps postal values as strings; missing fields remain empty rather than being replaced with invented values.
