Lot Number Search
See lot numbers on a map across Japan
Move from a street address or listing pin to parcel-level research, then get the official ownership record for that land. Search over 102M lot numbers across Japan, view them on the map, and continue into zoning, hazard, land price, and ordering the property registration record (touki). Because the touki is requested by lot number, lot number search is what makes getting the record straightforward.

Built for parcel-first property research
See lot numbers on the map
Inspect parcel context directly instead of relying only on a listing pin or street address.
Layer the rest of the research
Check zoning, hazard, land price, and surrounding context without leaving the map workflow.
Order the official registration record
Use the lot number to order the official registration record (touki) for a parcel, since the touki is requested by lot number rather than by street address.

The official record of ownership and rights for a parcel, requested by its lot 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 get the official property registration record (touki) with a lot number?
Yes. In Japan the official registration record, called touki, is requested by lot number (chiban) and building number, not by street address. Identifying the parcel is the first step, so once you have the lot number you can order the official touki for that land.
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.
