When foreign buyers calculate whether they can afford a Japanese condominium, they typically focus on the purchase price and mortgage payment. What catches many buyers off guard are the two mandatory monthly fees that every condo owner pays regardless of whether they have a mortgage or own the unit outright. Getting these wrong in your budget is a minor inconvenience. Buying into a condo with a structurally underfunded repair reserve is a potentially serious financial problem that the monthly numbers won't reveal without deeper investigation.
This guide explains both fees, how to evaluate whether a building's finances are healthy, and what to check before you sign.
The Two Monthly Fees Every Condo Owner Pays
Japanese condominiums operate under a shared ownership structure governed by a 管理組合 (kanri kumiai, owners' association). Every unit owner is automatically a member. The association maintains the common areas, coordinates building management, and administers two mandatory monthly contributions:
管理費 — The Management Fee
管理費 (kanrihi, management fee) covers the ongoing day-to-day costs of running the building. This includes:
- Professional management company fees (kanri gaisha that handles administration)
- Common area cleaning and maintenance (lobby, corridors, stairwells, elevator)
- Utilities for common areas (lighting, water, HVAC for shared spaces)
- Security — whether a part-time doorman, building cameras, or automated access systems
- Administrative costs including association meetings, accounting, and insurance premiums for common property
Management fees vary significantly by building type and amenities. A modest low-rise condo with no concierge services and minimal shared facilities might run ¥8,000–¥12,000 per month. A large tower block with a managed entrance, rooftop garden, fitness room, and 24-hour security can run ¥25,000–¥40,000 per month or more. The average across Chiba's resale condo stock sits roughly in the ¥12,000–¥20,000 range for units in typical mid-rise buildings.
Management fees are broadly predictable and relatively stable year to year. They are not the main financial risk in condo ownership.
修繕積立金 — The Repair Reserve Fund
修繕積立金 (shūzen tsumitatekin, repair reserve fund or long-term maintenance fund) is where the real due diligence is required.
This fund accumulates over time to pay for large-scale building repairs that occur cyclically: exterior waterproofing, roof replacement, elevator modernization, external wall repainting, and mechanical system overhauls. These are not surprise events — a concrete condominium building requires major work on a roughly 12–15 year cycle, and the cost per building can run into the hundreds of millions of yen.
The repair reserve is not a management expense. It is capital set aside today to pay for future work. When it is funded correctly, large repairs are paid from the accumulated balance with minimal impact on individual owners. When it is underfunded, the association faces two unpleasant options: defer repairs (degrading the building and its value), or issue a 一時金 (ichiji-kin, special assessment) requiring every owner to contribute a lump sum immediately.
Typical repair reserve fund contributions range from ¥5,000–¥25,000 per unit per month, but this figure alone tells you nothing. What matters is whether the accumulated balance is adequate relative to the building's upcoming repair obligations.
The Hidden Risk: Underfunded Repair Reserves
Japan's condo stock has a structural problem with repair reserves. When condominium buildings are first developed, repair reserve contributions are often set at artificially low levels — sometimes as low as ¥2,000–¥5,000 per month — to make the monthly ownership cost look attractive in marketing materials. The expectation is that contributions will be raised over time as the building ages. In practice, raising contributions requires a vote of the owners' association, and owners with financial pressure or short-term ownership horizons often vote against increases.
The result: many buildings that are now 20–35 years old are entering their most repair-intensive phase with inadequate accumulated reserves.
This is not a hypothetical risk. The Ministry of Land, Infrastructure, Transport and Tourism's surveys have found that a substantial minority of condominium owners' associations have repair reserve balances that are less than half of what their long-term repair plans require. When you buy into one of these buildings, you are inheriting a portion of that shortfall.
The Chiba Coastal Condo Problem
The Makuhari bay area in particular — including the large condominium complexes developed during and after the 1980s bubble economy — now has many buildings that are 30–40 years old and approaching major repair cycles. Exterior waterproofing, elevator replacements, and plumbing overhauls represent significant per-unit costs when concentrated in a single repair period. For buyers considering condos in Makuhari, Mihama-ku, or the reclaimed land zones of coastal Chiba, this due diligence is not optional.
Combined with the seismic and liquefaction considerations in these areas — covered in depth in our earthquake safety guide for Chiba homebuyers — the financial health of the building management structure is a critical evaluation criterion.
How to Assess Repair Reserve Fund Health
The 重要事項説明書 (jūyō jikō setsumeisho, property disclosure document) that every buyer receives before signing must include the current balance of the repair reserve fund and the current monthly contribution amount. This is a legal requirement.
However, the current balance alone does not tell you whether the fund is adequate. To assess reserve health properly, request:
長期修繕計画 — Long-Term Repair Plan
The 長期修繕計画 (chōki shūzen keikaku) is a detailed schedule of planned repairs and their estimated costs, projected over typically 25–30 years. It shows what large works are planned, when they are expected to be executed, and what the projected cost per unit will be.
Compare the plan's projected reserve balance at each major repair point against the planned expenditures. If the plan shows the reserve going negative — or close to zero — before a major repair cycle, a special assessment is likely.
A building with a properly funded reserve and a realistic long-term plan will show a gradually increasing contribution rate and a projected balance that stays positive throughout the planning horizon.
管理組合議事録 — Association Meeting Minutes
The 管理組合議事録 (kanri kumiai gijiroku, owners' association meeting minutes) is a record of what the association has discussed and decided in recent years. Request the last 2–3 years of minutes and look for:
- Any vote on contribution rate increases (approved or rejected)
- Discussion of upcoming large repairs or known building defects
- Any disputes among owners that may affect the building's governance
- Past special assessment votes — if there has already been one, this tells you the reserve was previously underfunded
Association minutes are not typically provided automatically; ask your agent to request them from the seller or management company. A seller who cannot or will not provide minutes is a red flag.
Special Assessments: The Lump-Sum Risk
If the repair reserve is insufficient when a major repair project is required, the owners' association will vote to impose a 一時金 (ichiji-kin, special assessment) on all unit owners. The amount varies by building size, unit size, and the specific repair required, but meaningful special assessments in the ¥500,000–¥2,000,000 per unit range are not unusual for major building envelope or elevator projects in older large-scale condominiums.
Special assessments are not disclosed in advance if they have not yet been decided — the jūyō jikō setsumeisho only captures known future levies. This is one reason that reviewing the long-term repair plan and meeting minutes is more informative than reviewing the disclosure document alone.
The Rising Fee Trend
Monthly repair reserve contributions at many Japanese condominiums have been rising as building stock ages and repair frequency increases. The government has published revised guidance on appropriate reserve fund levels, and more associations are updating their long-term plans to reflect current construction cost inflation. If you are buying into an older building with a currently low contribution rate, budget for the realistic probability that contributions will increase over your ownership period.
On a ¥40,000,000 condo, an increase of ¥10,000 per month in repair reserve contributions adds ¥120,000 per year to your holding cost. Over a 20-year ownership horizon, contribution increases will often have a larger cumulative impact on your cost of ownership than the initial contribution level suggests.
Parking Fees
If you own a designated parking space, expect a separate monthly fee of ¥5,000–¥20,000 depending on whether it is an at-grade space, a mechanical parking structure (機械式駐車場), or underground. Mechanical parking structures in particular carry high maintenance costs — elevator mechanisms require regular servicing and eventual replacement — and buildings with aging mechanical parking systems should be treated similarly to buildings with aging elevators when evaluating reserve fund adequacy.
In some buildings, parking fees are included in the management fee; in others they are billed separately. The jūyō jikō setsumeisho will specify.
Summary: What to Check Before Buying
| Item | Where to Find It | What to Look For |
|---|---|---|
| Current repair reserve balance | 重要事項説明書 | Is it plausible for the building's age and size? |
| Monthly repair reserve contribution | 重要事項説明書 | How does it compare to similar buildings? |
| Long-term repair plan | Request from seller/management company | Does balance stay positive through major repairs? |
| Association meeting minutes (2–3 years) | Request from seller/management company | Contribution rate debates, known defects, past special assessments |
| Past large repair history | Meeting minutes / management company records | What has been done, when, and at what cost |
| Upcoming scheduled repairs | Long-term repair plan | Is there a major repair within 3–5 years post-purchase? |

Bottom Line
Every Japanese condo owner pays two monthly fees: the management fee (kanrihi) and the repair reserve fund (shūzen tsumitatekin). The management fee is predictable and relatively straightforward. The repair reserve is where meaningful financial risk is hidden — particularly in Chiba's older coastal condominium stock where buildings built 25–40 years ago are now entering intensive repair cycles. Before committing to any condo purchase, request the long-term repair plan and the last two years of association meeting minutes, and verify that the projected reserve balance can cover scheduled repairs without requiring a special assessment. A few hours of due diligence on the building's finances can save you from an expensive surprise after closing.
