In 2025, the average transaction price for Chiyoda City overall (the All chart) appears to be slightly lower than in 2024. However, the room-type charts (3LDK, 2LDK, 1LDK, and 1K) show that average transaction prices rose sharply in every individual category.
This is because the number and average price of large building and land transactions, which can reach hundreds of millions to tens of billions of yen and are classified as "Other", declined in 2025. In the weighted average calculation, that dragged down the overall average significantly. This is a statistical effect known as Simpson's paradox. The underlying residential condominium market price trend remains very strong across all room types.
