Lifescape Marketing Inc. (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Kenji Ueda) has released the results of a survey on the consumption of donburi-style menus, targeting married households with wives aged 22 to 72 in the Tokyo metropolitan area (within a 30km radius) and individuals aged 20 and over belonging to these households. Over 30% Eat 'Donburi Dinner Once a Week'? A New Evening Meal Habit Spreading Among Younger Households A "donburi bowl" is a versatile dish, useful for both rice and noodle meals. Currently, "donburi-style menus," eaten from such bowls, are gaining prominence in evening meal scenes. Growth over the past decade has been remarkable: the Evening Meal TI Value (times per 1,000 dinner tables) rose from 97.5 in fiscal 2016 to 131.3 in fiscal 2025, a significant increase of 135% compared to 10 years prior [Figure 1, left side]. Why have donburi-style menus grown so much? Figure 1. [Figure 1, right side] shows the monitor distribution by eating frequency per 7 evening meals for donburi-style menus. Households that eat donburi-style menus at least once per 7 evening meals (hereinafter referred to as the 'Weekly Donburi Layer') have expanded from 22% in fiscal 2016 to 38% currently, an increase of +15.2 percentage points over 10 years. Further investigation reveals that this Weekly Donburi Layer is more common in younger family households. An analysis covering the three years from fiscal 2023 to fiscal 2025 found that in households where the wife is in her 20s or 30s, nearly half (43%) used donburi-style menus once a week or more. In contrast, among other age groups, 32% in their 40s, 28% in their 50s, and 15% in their 60s and above reported this frequency, with the proportion decreasing as age increased. From the perspective of household composition, 42% of households with young children, including elementary school age and younger, belonged to the Weekly Donburi Layer, a higher figure than other household types.
