About UR & JKK Public Housing
komadori's Mission
komadori is an independently operated site that automatically collects vacancy listings published on the official websites of UR (Urban Renaissance Agency) and JKK Tokyo (Tokyo Housing Supply Corporation) every day, and makes them searchable across rent, layout, and area in one place. Our goal is to make public rental housing in Japan more visible and easier to compare as a real housing option.
UR Rental Housing
UR rental housing is managed by the Urban Renaissance Agency (UR), a government-affiliated organization. UR apartments require no key money, no agent fees, no renewal fees, and no guarantor. With around 700,000 units nationwide, there are many properties available across Tokyo's 23 wards.
JKK Tokyo (Tokyo Housing Supply Corporation)
JKK Tokyo manages public corporation housing and metropolitan housing throughout the Tokyo area. These apartments offer relatively affordable rent. Corporation housing is open to general applicants, while metropolitan housing is available to those meeting income requirements.
Benefits of Public Housing
- No key money or agent fees — lower upfront costs
- No renewal fees — the longer you stay, the more you save
- No guarantor required (for UR housing)
- Well-maintained common areas and facilities
- Many properties near stations with spacious layouts

Frequently Asked Questions
How is komadori different from the official UR and JKK websites?
komadori automatically collects vacancy listings from both the UR and JKK Tokyo official websites daily and presents them on a single site. Instead of searching each site separately, you can compare and search across both UR and JKK vacancies at once. We also provide unique analytics like vacancy history and fill-speed ratings.
How often is the data updated?
Vacancy information is updated automatically every day. Since our data is sourced from the official websites, there may be a slight delay compared to real-time availability. For the latest status, please check each property's official page.
How do I apply for a UR or JKK apartment?
When you find a property you're interested in on komadori, use the "UR Official Page" or "JKK Official Page" link on the property detail page to visit the official website and apply there. You cannot apply directly through komadori.
What does "How Fast It Fills" mean?
"How Fast It Fills" is a unique metric based on historical vacancy data. It calculates the average number of days between a vacancy appearing and being contracted. "High" means within 7 days on average, "Medium" within 30 days, and "Low" means longer. Popular properties require quicker decisions.
Is this site free to use?
Yes, komadori is completely free to use with no registration required. While we are an independent site with no affiliation to UR or JKK Tokyo, we strive to provide accurate and easy-to-browse vacancy information.
