[2026 Update] Why Nagakute, Aichi is Japan's Youngest City: An In-Depth Look at How Unique Childcare Support and Linimo Line Developments Boost Land Prices and Livability

Nagakute City, Aichi Prefecture (愛知県長久手市), is drawing nationwide attention after surging to 3rd place overall in the nationwide "2026 Livability Ranking (住みよさランキング2026)" published by Toyo Keizai Inc. (東洋経済新報社). Continuously developing as a commuter town for Nagoya City (名古屋市), it is widely known as "Japan's youngest city," boasting one of the lowest average resident ages in the country.

Why does Nagakute City attract so many child-rearing generations and maintain steady population growth over the years? Furthermore, is the asset value of this city genuinely solid, not only for owner-occupier homebuyers but also for real estate investors with a long-term perspective?

This article provides an in-depth analysis of Nagakute City’s unique and comprehensive childcare support measures updated for 2026, as well as the current state of commercial and infrastructure development progressing along the Linimo (リニモ) line. Using actual real estate transaction data and hazard information as evidence, we will unravel the correlation between livability and rising land prices, revealing the true investment potential of this thriving commuter town.

【Nagakute City, Aichi Prefecture Area Summary (As of September 2026)】

1. Why is Nagakute City, Aichi Prefecture Called "Japan's Youngest City"?

The primary reason Nagakute City is hailed as "Japan's youngest city" lies in its continuous population influx and the resulting overwhelmingly high proportion of young people and families. According to estimates from June 2026, the Nagakute District (長湫地区), which spans the western to southern parts of the city, exceeded a population of 50,000 on its own, showing that its growth speed knows no bounds.

This wave of population growth directly correlates with a booming real estate market. According to actual data retrieved from our media's backend system (such as the API from the Ministry of Land, Infrastructure, Transport and Tourism (国土交通省)), the number of real estate transaction samples in the target area from 2021 to 2025 reached 1,149. This is an exceptionally active transaction level for a commuter town near a regional core city.

The continuous influx of new residents stimulates a wide range of housing demand, from pre-owned condominiums to newly built detached houses, actively driving the metabolism of the entire city. For both prospective owner-occupiers looking to settle down long-term and real estate investors anticipating solid rental demand, a city with such a clear growth factor as "population increase" is an extremely rare find.

2. Nagakute City's Unique Childcare Support Measures that Attract Families

Robustly supporting Nagakute City's population growth are the generous childcare support measures led by the local government. As of 2026, Nagakute City is implementing unique policies that put it one step ahead of other municipalities.

Most notably, medical expenses (both outpatient and inpatient) are completely free of charge until the end of the fiscal year when a child turns 18 (high school age). Furthermore, a total of 100,000 yen equivalent is provided as a childbirth support grant, ensuring seamless financial support from pregnancy and childbirth through to high school graduation.

Additionally, starting in fiscal year 2026, the "Infant Nursery Attendance Support Program (Universal Children's Nursery System)" officially launched in nurseries within Nagakute City (such as Nagakute Higashi Nursery School (長湫東保育園)), preempting the government's new national system. This allows families with children between 6 months and under 3 years old to use childcare facilities flexibly, regardless of the parents' employment status, significantly contributing to alleviating the childcare burden not only for dual-income households but also for stay-at-home parent families.

Looking at actual living environment data, the target area is designated within the school zones for Nagakute Elementary School and Nagakute Junior High School, ensuring a well-established educational infrastructure. This enrichment of both soft (systems) and hard (school facilities) aspects serves as a powerful incentive, making families with children feel, "I want to live here."

💡 【Homebuying & Investment Tip】 Areas with generous childcare support boast high retention rates among families, leading to solid, ongoing demand for spacious family-oriented properties like 3LDKs (3 bedrooms, living, dining, and kitchen) or larger.

3. The Evolution Along the Linimo Line! A Rich Living Environment Where Large Commercial Facilities and Parks Intersect

When discussing the appeal of Nagakute City, the dynamic urban development along the Tobu Kyuryo Line, known as "Linimo," is indispensable.

Redevelopment Overview

Nagakute City is already home to a concentration of facilities with nationwide drawing power, such as Aeon Mall Nagakute (イオンモール長久手), IKEA Nagakute (IKEA長久手), and Ghibli Park (ジブリパーク) within the Aichi Earth Expo Memorial Park (愛・地球博記念公園). However, the city's evolution does not stop there.

In March 2025, a large supermarket themed as a "food theme park," Beisia Foods Park Nagakute Store (ベイシア Foods Park 長久手店), newly opened very close to the Linimo Koen Nishi Station (公園西駅). This marks the first new store opening in Aichi Prefecture in 13 years, dramatically improving the convenience of daily shopping. Furthermore, inside Aeon Mall Nagakute, commercial facility updates are continuously progressing, such as the new opening of a luxury purchasing shop Otakaraya (高価買取おたからや) in August 2026.

In addition, Nagakute Onsen Gozarasse (長久手温泉ござらっせ), long cherished as a relaxation spot, reopened with a new look in August 2026, now featuring four different types of saunas. Moreover, the basic plan for the Sports Forest Redevelopment Project (スポーツの杜再整備事業) promoted by Nagakute City has been finalized, moving forward with the development of an outdoor sports hub where multiple generations can interact. A living environment where commercial convenience seamlessly intersects with nature and leisure is precisely Nagakute City's greatest weapon.

4. How Livable is it Actually? The Living Infrastructure Valued by Homebuyers

When searching for a home, "safety" and "daily infrastructure" are even more important than commercial facilities. Based on actual data obtained by our media, we will examine the realistic living environment of Nagakute City.

First, regarding the hazard information that must be checked before purchasing real estate, the data for the target location (near the center of Nagakute City) indicates "Flood Risk: None (maxDepthRank: null)" and "Landslide Risk: None." With growing concerns about the intensification of natural disasters nationwide in recent years, being in an elevated or flatland area with low risks of water damage and landslides serves as the ultimate reassurance for prospective homebuyers.

Additionally, the zoning designation that establishes the rules for the surrounding environment is a "Category I Residential District," securing a spacious living environment with a building coverage ratio of 60% and a floor area ratio of 200%. It is a well-balanced area that ensures natural light and ventilation for homes while allowing moderately sized stores to be located nearby.

Medical infrastructure is also comprehensive; actual data confirms the presence of four medical institutions, including Aichi Medical University Hospital (愛知医科大学病院) and Nagakute City Health Center Clinic (長久手市保健センター診療所). Furthermore, according to the latest plans, the Nagakute City Kanihara Medical Center (tentative name) (（仮称）長久手市蟹原メディカルセンター) is scheduled for completion around the Linimo Irigaike Koen Station (杁ヶ池公園駅) in 2029, which will make the future medical system even more robust.

It should be noted that in the public API data used this time, some individual fields, such as specific nearest station names and passenger volume, were output as "null (no data)." In reality, however, each station on the Linimo line functions as a crucial means of daily transportation for citizens. Because there are parts that are hard to see purely through data (blank data), on-site inspections and analysis cross-referenced with the latest regional plans are essential.

💡 【Homebuying & Investment Tip】 Low hazard risk and comprehensive medical infrastructure act as the strongest defensive wall to preserve a property's long-term asset value. Check the latest land price and hazard information for Nagakute City, Aichi Prefecture on Mekiki Research 👉

5. Land Price Trends and Asset Value Improvement Brought by Population Growth in Nagakute City

Impact on Land Prices

How are this comprehensive infrastructure and population growth affecting actual real estate prices? Analyzing the 1,149 transaction records obtained (2021-2025) clearly highlights the resilience of Nagakute City's real estate market.

During the target period, the average transaction price was approximately 43.56 million yen, the median was approximately 34 million yen, and the average unit price was recorded at about 150,000 yen/sqm. Below are some transaction examples extracted from the actual data.

【Real Estate Transaction Examples in Nagakute City (Extracted from Actual Data)】

Recently built detached houses (in the Ibori area) are being traded at high levels exceeding the 50 million yen mark, while even pre-owned condominiums around 10 years old are being stably bought and sold in the 30 million to 40 million yen range. This shows that while it feels reasonably priced compared to central Nagoya City, its asset value is firmly maintained.

6. Future Potential and Stability as a Commuter Town from a Real Estate Investment Perspective

Future Investment Potential

When purchasing real estate, the most important aspect is the "future scenario." We have organized a timeline format of future predictions for the target area to illustrate how Nagakute City will mature moving forward.

• 2026 (Present): Full-scale implementation of the "Universal Children's Nursery System" and the reopening of Nagakute Onsen Gozarasse, rapidly advancing the development of childcare and living environments from both soft and hard perspectives. The population of the Nagakute District has surpassed 50,000, solidifying the foundation for housing demand.
• 2028: The final year of the "6th Nagakute City Comprehensive Plan: Late Action Plan 2024-2028 (第6次長久手市総合計画 後期アクションプラン2024～2028)" promoted by the local government. Urban development policies up to this point will culminate, with infrastructure development expected to reach a certain level of completion.
• 2030: The Nagakute City Kanihara Medical Center (tentative name), scheduled for completion the previous year, will commence full-scale operations. Through the expansion of medical and welfare infrastructure, the city will mature into a place chosen as a "final home" even by seniors who have finished raising their children.

What can be read from this timeline is the fact that Nagakute City is not merely a "temporarily trendy city," but is systematically building an ecosystem that generates intergenerational circulation. As a benchmark for investment decisions, its greatest potential lies not in aiming for short-term capital gains (profits from sales), but rather in securing stable, long-term income gains (rental income), or the "ease of selling" (high liquidity) when owner-occupiers relocate to match changes in their life stages.

💡 【Homebuying & Investment Tip】 Cities with clear future administrative plans experience less fluctuation in asset value 10 or 20 years down the line, making them the optimal choice for solid real estate investment and purchase.

7. Key Points and Considerations When Searching for Properties in Nagakute City

While Nagakute City is full of charm, there are several points to keep in mind when actually purchasing a property. Looking closely at the actual data reveals factors causing price disparities even within the same region.

For example, let's look at the pre-owned condominium transactions in the "Higashiharayama" district mentioned in the earlier data.

• Higashiharayama: 3LDK / Built in 2017 / Quasi-Industrial District / Approx. 32 million yen (Area 80㎡)
• Higashiharayama: 3LDK / Built in 2017 / Quasi-Industrial District / Approx. 29 million yen (Area 75㎡)
• Higashiharayama: 3LDK / Built in 1994 / Category II Mid/High-Rise Residential District / Approx. 19 million yen (Area 75㎡)

Even for a 3LDK in the same district, differences in the year built (2017 vs. 1994) can result in a price gap of over 10 million yen. Also, what cannot be overlooked is the difference in zoning districts. Even within Higashiharayama, "Quasi-Industrial Districts" and "Category II Mid/High-Rise Residential Districts" coexist.

While quasi-industrial districts make it easier to build daily convenience facilities, there is also the possibility of factories and warehouses being situated nearby. Do you prioritize a quiet living environment, or convenience? Although the hazard risk is generally low in this area, such micro-location conditions (zoning districts, building coverage ratios, and floor area ratios) dictate day-to-day livability and future asset value. Before purchasing, it is crucial to always check the zoning district in the data and walk around the local area to experience the neighborhood's atmosphere firsthand.

💡 【Homebuying & Investment Tip】 Understanding in advance the risk of the surrounding environment changing in the future depending not only on the building age but also on the zoning district is an ironclad rule for foolproof property selection.
