LIXIL Housing Research Institute Survey: Child-Rearing Ease, Floor Plans, and Relaxing Living Rooms Top Conditions for a Happy Home

LIXIL Housing Research Institute conducted a survey on the conditions people associate with a “home” that brings happiness, what aspects of housing they feel positively affect mental and physical health, and what spaces or facilities they would like at home to improve their well-being. Valid responses were collected from 600 married dual-income men and women in their 20s to 40s with children, consisting of 300 men and 300 women. The survey was conducted from February 16 to 22, 2026. When respondents were asked to select the top three important factors affecting their happiness and the results were analyzed using a weighted average, “family” ranked first at 43.9%. When asked about the conditions of a “home” that brings happiness, the top response was “easy to raise children in” at 46.8%, followed by “floor plan” at 44.8% and “a relaxing living room” at 41.0%. For factors in the home that positively affect mental and physical health, the top three were “space to spend time with family and friends” at 29.6%, “appropriate temperature and humidity” at 22.8%, and “good sunlight and brightness” at 20.9%. Conversely, factors viewed as negatively affecting mental and physical health included “cold in winter and hot in summer” at 19.7% and “insufficient storage and clutter” at 18.8%. The results suggest that many people feel appropriate indoor temperature and humidity influence their mental and physical health. As for spaces and facilities respondents would like at home to improve mental and physical health, “high-quality bedding for sleep” ranked first at 26.8%, followed by “a relaxing bathroom” at 23.8% and “a highly soundproof room” at 21.7%. The survey also found that 71.5% of respondents have high awareness of home security. Incidents and accidents that caused anxiety in daily life over the past year included “child abduction” at 28.0%, “fire, arson, or fire spreading from nearby properties” at 27.3%, and “home intrusion such as burglary” at 27.2%, all exceeding 25%.
