Terms people mix up

Lot number / 地番

Street address / 住居表示

Useful for navigation and mail, but not always the same as the parcel identifier.

Building number / 家屋番号

A building registry identifier, not the land parcel number.

FAQ

Can I find a lot number from an address?

Often yes as a research step, but an address alone should not be treated as final parcel confirmation.

Can I compare street addresses and lot numbers?

Yes. This workflow is designed to start from an address or listing and resolve toward the parcel you actually need to research.

Does this replace official registry confirmation?

No. It speeds up parcel identification and map-based research before deeper official confirmation.

Does it work across Japan?

It is built for nationwide lot number research workflows in Japan. Start by opening the target area on the map.

Once you have the lot number, keep the research moving

After parcel identification, continue into zoning, hazard, land price, listings, and registry-oriented work from the same workspace.
