Working back from your daily requirement
Adult energy requirements vary with body size and activity, but according to Japan’s Dietary Reference Intakes (MHLW), most fall between 1,800 and 2,600 kcal a day. At 2,000 kcal split evenly across three meals, one meal comes to about 670 kcal — or around 600 kcal if you allow for snacks.
You can estimate your own figure with the calorie calculator.
How restaurant items actually distribute
Across the 191 chains we cover, 20,539 items are meals (excluding drinks, desserts and condiments). They average 598 kcal, with a median of 540 kcal, and 47% come in under 500 kcal.
The average sits below the 600 kcal guide because many entries are single sides or a single piece of sushi — items that do not make a meal on their own. In practice you combine several, so it is the total that matters.
Differences by genre
| Genre | Items | Avg kcal | Median | Under 500 |
|---|---|---|---|---|
| Curry | 131 | 949 | 939 | 10% |
| Noodles | 2,958 | 849 | 838 | 18% |
| Beef Bowls & Donburi | 827 | 813 | 783 | 16% |
| Set Meals & Bento | 1,889 | 732 | 723 | 29% |
| Family Restaurants | 6,046 | 684 | 660 | 30% |
| Yakiniku & Shabu-shabu | 765 | 666 | 595 | 45% |
| Burgers | 482 | 498 | 425 | 67% |
| Cafes | 1,101 | 493 | 414 | 62% |
| Pizza & Delivery | 1,670 | 410 | 186 | 79% |
| Sweets & Donuts | 20 | 399 | 336 | 75% |
| Convenience Stores | 1,802 | 391 | 351 | 74% |
| Izakaya | 235 | 352 | 302 | 78% |
| Meal Delivery & High-Protein | 1,057 | 324 | 305 | 96% |
| Sushi | 1,548 | 221 | 131 | 87% |
Curry is highest at 949 kcal on average, since a single rice-bowl dish is already a complete meal. Meal Delivery & High-Protein averages 324 kcal, but that is because each item is small and normally combined with others.
Cutting calories when eating out
Within a single restaurant, the choice alone can shift the total by several hundred kcal — at many chains the gap between the lightest and heaviest meal exceeds 1,000 kcal. What you order usually matters more than where you go.
- Drop one size — regular to large is often 200–300 kcal
- Remove one fried item — batter and oil raise density sharply
- Check what the set adds — a drink and side can add 200–400 kcal
- Look it up before you go in — it is hard to change your mind after ordering
