Anyone researching land purchases or sales will inevitably come across the terms “official land price” and “actual market price.” Understanding the difference between these two helps you identify an appropriate transaction price for land and make more accurate investment decisions. This article explains each price category in a structured way, including its definition, calculation method, and how to research it.
What Is the Official Land Price?
The official land price is the standard land value published each year by the Land Appraisal Committee of Japan’s Ministry of Land, Infrastructure, Transport and Tourism.It is also referred to as a “normal price,” meaning an appropriate price established in an ordinary transaction without special circumstances such as a rushed sale or purchase. Under the Land Price Public Disclosure Act, prices as of January 1 are published each March for approximately 23,000 standard sites across Japan. These figures are also used together with the benchmark land prices from the prefectural “Land Price Survey,” which serves a complementary role.
What Is the Actual Market Price?
The actual market price is the price at which a real estate transaction was actually concluded, or is expected to be concluded.Because it varies based on supply and demand, location conditions, and the circumstances of both seller and buyer, it can differ from one transaction to another even within the same area. Historical actual market prices are published through the Ministry of Land, Infrastructure, Transport and Tourism’s “Comprehensive Land Information System.”
How Are the Official Land Price and Actual Market Price Related, and How Are They Calculated?
The actual market price is generally considered to be about 1.1 to 1.2 times the official land price. That allows you to estimate a reference price using the following formula.
- Estimated actual market price ＝ official land price × area × 1.1 (or 1.2)
However, this is only a reference value, and the actual result may diverge significantly depending on the area and property-specific factors.
Four Ways to Research the Actual Market Price
Use the Comprehensive Land Information System
The Ministry of Land, Infrastructure, Transport and Tourism’s “Comprehensive Land Information System” lets you review past transaction records in both map and list formats. You can also see land area, lot shape, distance to the nearest station, and similar details at a glance, making it useful as foundational data for investment decisions.
Work Backward from the Assessed Value for Fixed Asset Tax
The assessed value for fixed asset tax is typically about 70% of the official land price. You can estimate the actual market price using the following formula.
- Assessed value for fixed asset tax ÷ 0.7 × 1.1 ＝ estimated actual market price
Calculate from Official and Benchmark Land Prices
Use the Ministry of Land, Infrastructure, Transport and Tourism’s “Standard and Benchmark Value Search System” to find the area’s official land price (per square meter), then calculate an estimate with the following formula.
- Official land price × area × 1.1 ＝ estimated actual market price
Calculate from the Roadside Land Value
Check the roadside land value in the National Tax Agency’s “Roadside Land Value Maps and Valuation Multiplier Tables,” then use the following formula. The roadside land value is typically about 80% of the official land price.
- Roadside land value × area ÷ 0.8 × 1.1 ＝ estimated actual market price
Key Pricing Gap Points Investors Should Understand
The gap between the official land price and the actual market price is an important indicator that reflects local popularity and supply-demand trends. In highly sought-after urban areas, the actual market price may exceed 1.5 times the official land price, while in regional areas it may fall below the official land price.For investment decisions, it is essential not to rely on a single pricing indicator, but to make a comprehensive assessment using multiple research methods.

Frequently Asked Questions (FAQ)
Q. Which is a more accurate measure of land value: the official land price or the actual market price?
A. It depends on the purpose. The official land price is a government-defined benchmark with high objectivity, while the actual market price is the price at which a real transaction is concluded. For investment and sale decisions, it is important to consider both.
Q. Which method is the most reliable for researching the actual market price?
A. Historical transaction data from the Comprehensive Land Information System gives the closest view of actual market pricing. However, we recommend combining multiple methods so your assessment also reflects recent market conditions.
Q. Are there cases where the official land price is higher than the actual market price?
A. Yes. In regional or sparsely populated areas, weak demand may cause the actual market price to fall below the official land price. When making an investment decision, you should always confirm local transaction examples.
Q. What is the difference between the roadside land value and the official land price?
A. The roadside land value is set by the National Tax Agency for inheritance and gift tax calculations, and it is typically about 80% of the official land price. The official land price is set by the Ministry of Land, Infrastructure, Transport and Tourism as a transaction benchmark.
Q. Which estimated market price formula is closest to real-world conditions?
A. It varies by area, but in practice the most reliable approach is generally to combine “assessed value for fixed asset tax ÷ 0.7 × 1.1” with “transaction examples from the Comprehensive Land Information System.”
