### ■ Growth in Rents for Small Single-Occupancy Units in Tokyo's 23 Wards is Slowing
#### 【Tokyo's 23 Wards】
In Tokyo's 23 wards, vacancy rates continue to improve across all floor area ranges for both apartments and condominiums. Growth in average apartment rents has slowed, except for units for couples (30–50㎡). Similarly, rent growth for small single-occupancy condominium units (0–20㎡) has slowed. This suggests that rental revisions and tenant turnover for units with poor conditions—such as those far from stations, older buildings, or small layouts—are not progressing.
#### 【Kanagawa Prefecture】
In Kawasaki City, vacancy rates continue to improve across all ranges. However, excluding apartments and condominiums over 50㎡ and condominiums between 20–30㎡, rents have declined month-on-month. In Yokohama City, vacancy rates continue to improve across all ranges. While rents for single-occupancy units (0–20㎡, 20–30㎡) are sluggish, rents for couples (30–50㎡) and families (over 50㎡) continue to rise, albeit below the inflation rate, indicating a shift from potential homebuyers priced out of the condominium market.
#### 【Saitama Prefecture】
In Saitama City, vacancy rates continue to improve across all ranges. While condominium rents (excluding 30–50㎡ units) have kept pace with inflation, apartment rent growth remains sluggish. Notably, rents for family units (over 50㎡) continue to fall, suggesting that properties with poor conditions are being avoided.
#### 【Chiba Prefecture】
In Western Chiba Prefecture, vacancy rates continue to improve across all ranges. However, rents for single-occupancy units (0–20㎡, 20–30㎡) remain on a downward trend. Rents for couple and family units are also soft, suggesting that properties with poor conditions may be lowering rents to fill vacancies.
