About
UR rentals in Tokyo go fast, and the official site has no alerts. I was checking it by hand every day, so I built a service to do it for me.
You can start with one saved search without signing up. Sign in with Google later and your searches and history come with you. To ask in a chat with Claude or ChatGPT instead, there's UR MCP App.
In October 2026 I merged this with UR MCP App into UR Check and shut this one down.
What it does
- Saved searches
- Area, rent, floor space, layout and walk time across Tokyo, Kanagawa, Chiba, Saitama and Ibaraki.
- Scheduled checks
- Each search is checked on its own interval between 08:00 and 20:00 JST.
- Change-only emails
- One summary when you turn alerts on, then only rooms that are new or listed again.
- Guest to member
- Searches and history move over in one step when you sign in with Google.
- History
- Every check and every email is listed with its result.
