Marugame and Sakaide Real Estate Investment | Analysis of Seto Ohashi Bridge Effect, Industrial Zone, and Udon Tourism Demand
Investment Environment in the Marugame-Sakaide Area
Located in central-western Kagawa Prefecture, Marugame City (population approximately 110,000) and Sakaide City (population approximately 50,000) are economic hubs in the prefecture second only to Takamatsu City. Sakaide City, which serves as the Shikoku-side starting point of the Seto Ohashi Bridge, and Marugame City, which houses Marugame Castle, provide unique investment opportunities as key points for industry, tourism, and transportation.
Among the four Shikoku prefectures, Kagawa Prefecture has the smallest area and highest population density, forming relatively compact living areas despite being regional cities.

Seto Ohashi Bridge Effect and Transportation Infrastructure
Advantages Brought by the Seto Ohashi Bridge
The Seto Ohashi Bridge, which opened in 1988, is a combined railway and highway bridge connecting Shikoku and Honshu. Sakaide City serves as the Shikoku-side starting point and is positioned as a transportation hub as the junction of the JR Seto-Ohashi Line.
Investment Effects of Transportation Access
| Direction | Travel Time | Access Method | |-----------|-------------|---------------| | Okayama Station | Approx. 40 min | JR Seto-Ohashi Line | | Takamatsu Station | Approx. 15 min | JR Yosan Line | | Matsuyama Station | Approx. 2 hours | JR Yosan Line Express | | Kansai Region | Approx. 2.5 hours | Expressway via Seto Ohashi |
Sakaide Station is a major transfer station for JR Shikoku, and its function as a hub for commuting supports rental demand. There are cases where commuters to the Okayama area reside in Sakaide and Utazu, making Seto Ohashi commuter demand an important factor in investment decisions.
Marugame Castle Tourism and Surrounding Investment
Marugame Castle as a Tourist Resource
Marugame Castle is one of Japan's 12 remaining original castle keeps with the tallest stone walls in the country, attracting approximately 400,000 visitors annually. The surrounding area is seeing an increase in renovated traditional townhouses converted into shops and guesthouses.
Investment patterns include townhouse cafe rentals (acquisition + renovation ¥4-9 million, yield 10-15%), guesthouses (¥5.5-11 million, equivalent to 10-18%), and regular rentals (¥3-6.5 million, 11-14%).
Bannosu Industrial Zone and Industrial Demand
Overview of the Industrial Zone
The Bannosu district in Sakaide City is an industrial park developed in conjunction with the construction of the Seto Ohashi Bridge, where large-scale factories for petroleum refining, chemicals, steel, and other industries are located. Major corporate production bases are concentrated here, including Cosmo Oil's refinery.
Impact of Industrial Demand on the Rental Market
| Demand Segment | Scale | Rent Range | Contract Type | |----------------|-------|------------|---------------| | Regular Employees (Transferees) | Approx. 1,500 people | ¥40,000-55,000 | Many corporate contracts | | Contract/Temporary Workers | Approx. 800 people | ¥30,000-40,000 | Individual contracts | | Periodic Maintenance Workers | Variable | ¥35,000-45,000 | Short-term (1-3 months) |
Periodic maintenance (shutdown maintenance) at the Bannosu industrial zone occurs every few years, with temporary influx of several hundred workers. Properties capable of monthly rentals can expect high profitability.
Udon Pilgrimage Tourism Demand
Kagawa Prefecture's udon pilgrimage tourism maintains stable year-round appeal, with numerous famous shops in both Marugame and Sakaide cities. In recent years, multi-day "staying pilgrimages" are becoming established, making strategies to capture accommodation demand through guesthouses and vacation rentals effective.
Area of Interest: Utazu Town
Utazu Town, sandwiched between Marugame and Sakaide cities, is an area of interest with a slight population increase despite its small area of approximately 8.5 km². JR Utazu Station is a JR Shikoku express stop with high living convenience due to large commercial facilities like Aeon Town Utazu and Gold Tower.
| Indicator | Utazu Town | |-----------|------------| | Population | Approx. 18,000 | | Population Growth Rate | +0.1%/year | | 1K Rent Market Rate | ¥40,000-50,000 | | Vacancy Rate | 8-12% | | Investment Suitability | ★★★★★ |
Utazu Town has the lowest vacancy risk in the Marugame-Sakaide area and is recommended as a stable investment destination.
Investment Risks and Countermeasures
Main risks include accelerating population decline in Sakaide City (-0.8%/year), factory downsizing/withdrawal, Nankai Trough earthquake tsunamis, and downtown hollowing out. Mitigate risks through concentrated investment in Utazu Town and Marugame Station areas, hazard map verification, and monitoring industrial zone operational trends.
Investment Strategy Summary
| Strategy | Area | Yield Target | Initial Investment | Recommendation | |----------|------|--------------|-------------------|----------------| | Industrial Demand Type | Bannosu Area | 11.5-14.5% | ¥2-5 million | ★★★★ | | Marugame Station Singles | Marugame Station Area | 10-13% | ¥2.5-6 million | ★★★★ | | Utazu Stable Investment | Utazu Town | 9-11.5% | ¥4-8 million | ★★★★★ | | Tourism Renovation | Around Marugame Castle | 10-18% equivalent | ¥4-10 million | ★★★ | | Sakaide Station Front | Sakaide Station Area | 10.5-13.5% | ¥2-5 million | ★★★ |
The Marugame-Sakaide area has significantly lower property prices compared to Takamatsu City, making it easier to achieve high yields. It is suitable for long-term investment focused on income gain, leveraging connectivity to Honshu via the Seto Ohashi Bridge and stable employment in the industrial zone.
