When I bought my third rental unit, a compact condo near a train station, I nearly skipped over the line item that ended up costing me more than the mortgage interest over ten years: common area maintenance. On paper it looked like a flat 18,500 yen a month, but by year six that number had climbed to almost 24,000 yen, and I had not touched a single light bulb in the hallway myself.
Common area maintenance fees, known as kanrihi, and the separate reserve fund contribution, known as shuzen tsumitatekin, are two of the most misunderstood costs in Japanese condo investing. Get them wrong in your projections and your cash flow falls apart before you have even collected the first month of rent.
Kanrihi vs Shuzen Tsumitatekin: Two Very Different Buckets

Real Estate Investment Books
The books that changed how I think about money, leverage, and long-term wealth.
These two costs get lumped together on listing sheets as one monthly common area fee, but they serve completely different purposes, and understanding the split matters when you are underwriting a deal. Kanrihi pays for the day to day running of the building: cleaning staff who sweep the entrance a couple of times a week, the elevator maintenance contract, common area electricity and water, fire insurance on shared spaces, and the fee paid to the management company that handles all of it. Shuzen tsumitatekin is a completely separate pot, usually held in a dedicated bank account, that funds major repairs on a 12 to 15 year cycle: repainting the exterior, waterproofing the roof and balconies, and eventually replacing shared plumbing. Across the nine buildings where I own units, monthly kanrihi runs anywhere from 8,000 to 15,000 yen per unit, while tsumitatekin ranges from 6,000 to 20,000 yen depending on the age and size of the building.

Numbers vary more than most new investors expect. One building I own in, built in 1998 with 42 units, has a combined monthly common area cost of 27,000 yen per unit today. A newer building I bought into, completed in 2015 with 30 units, currently runs 19,500 yen combined. The gap is not random: the older building needed a special assessment in 2019 that raised the tsumitatekin portion by roughly 40 percent after the board realized the reserve fund would not cover an upcoming roof replacement. I was not thrilled to receive that notice, but I would have been far angrier discovering the shortfall after already owning the unit for five years.
Building These Costs Into My Investment Numbers
When I run numbers on a listing, I treat kanrihi and tsumitatekin as fixed operating costs, not fees I can trim the way I might switch out a rental management company. On a unit renting for 85,000 yen a month, a combined common area cost of 25,000 yen eats close to 29 percent of gross rent before I even account for property tax, vacancy, or my own time. That is a meaningful chunk, and it is one reason I now favor smaller, newer buildings with 20 to 35 units over the large 60-plus unit complexes that look attractive on a rental yield spreadsheet but often carry higher tsumitatekin per square meter once the building passes the 15 year mark.

Spreadsheet analysis is the difference between a good deal and a disaster.
When I request a detailed statement instead of just the monthly total, here is what typically shows up:
- Management company fee, usually 15 to 20 percent of total kanrihi collected
- Cleaning staff wages for common hallways, entrances, and trash rooms
- Elevator maintenance contract, often 30,000 to 50,000 yen per month for the whole building
- Common area electricity for hallway lighting, security cameras, and intercoms
- Fire and liability insurance covering shared spaces
- Monthly top-up to the long-term reserve fund
Why Older Buildings Cost More
Every reinforced concrete building in Japan follows something close to the same repair rhythm. Exterior repainting and waterproofing typically happens every 12 to 15 years, and for a 40-unit building that single project can run 80 to 120 million yen total. If the reserve fund was underfunded from the start, which happens more often than buyers assume, owners get hit with a special assessment on top of their regular monthly payment. I have seen assessments as small as 50,000 yen per unit and as large as 400,000 yen per unit for a full pipe replacement project. Buildings older than 25 years without a properly updated repair plan are where I see the biggest surprises.
How I Check the Reserve Fund Before I Buy
Before I make an offer on any condo unit now, I ask the seller’s agent for the choki shuzen keikaku, the long-term repair plan, and the most recent reserve fund balance sheet. I divide the total reserve balance by the number of units in the building. For a building over 15 years old, if that per-unit figure comes out below roughly 400,000 to 500,000 yen, I treat it as a warning sign and factor a likely special assessment into my return calculations. I also ask about the delinquency rate on kanrihi payments. If more than 5 to 10 percent of owners are behind, that tells me the building association may struggle to fund repairs even with a healthy reserve on paper, because collections are not keeping pace with obligations.
I do not skip this step anymore, no matter how good the headline yield looks on a listing. That is the approach I use across all 9 of my properties.
