Izu’s transaction data points to a cheaper but thinner market for buying premises through a house purchase. In 2025, the median house price was ¥10,000,000, down sharply from ¥24,000,000 in 2023 and ¥15,000,000 in 2024, with a 5-year house price CAGR of -14.59% and an overall trend marked down. Liquidity is modest rather than deep: 55 house transactions last year, or 0.574 per 1,000 residents.
This profile best suits buyers targeting older premises rather than newer stock. The old-house median was ¥9,800,000 in 2025, very close to the overall house median, while the akiya proxy ratio is high at 0.4545 and vacancy stands at 4,940 homes, or 12.19% of stock. That said, only 0.506% of vacant homes appear to turn into annual transactions via the akiya mobilization ratio, so there may be visible vacant stock without fast market conversion. Demographically, the municipality is older (31.51% aged 65+) and losing residents on net (-199, or -0.21%), with a day-night ratio of 0.93, so this is more a value-and-adaptation market than a growth-led one. On local affordability metrics, the price-to-income ratio is 3.04.
The main caveat is that these are broad residential transaction aggregates, not business-premises sales, so they indicate acquisition conditions only indirectly. Annual medians and counts are also volatile here: transactions ranged from 43 to 97 over 2019–2024 before falling back to 55 in 2025, and medians moved from ¥24,000,000 in 2023 to ¥10,000,000 in 2025. Vacancy, income, and migration figures also come from different source years than the 2025 transaction data, so they are useful context but not a same-year snapshot.
