About Minolier

A simpler way to read seasonality, origin, price, and nutrition data

1. What Minolier Is

Minolier is a data site for Japanese fruits and vegetables, organized around seasonality, origin, price, and nutrition. Data is drawn from official government sources including the Ministry of Agriculture, Forestry and Fisheries (MAFF), the Statistics Bureau, and the Ministry of Education (MEXT).

It is designed to make everyday food choices easier to compare with actual data, not just intuition.

2. What You Can See Here

  • Monthly season calendars and availability by produce item
  • Production rankings and major growing prefectures
  • Annual and monthly retail prices, plus wholesale market data
  • Nutrition per 100g and nutrient rankings

3. Data Sources

The primary data sources used on this site are:

  • MAFF "Crop Statistics Survey" (e-Stat — Portal Site of Official Statistics of Japan)
  • MAFF "Wholesale Market Survey for Fruits and Vegetables"
  • Statistics Bureau of Japan "Family Income and Expenditure Survey"
  • Statistics Bureau of Japan "Retail Price Statistics Survey"
  • Ministry of Education "Standard Tables of Food Composition in Japan"

These datasets are used in accordance with each ministry's terms of use, with attribution. In some cases, the data is processed and reorganized for clarity and presentation on this site.

4. Disclaimer

  • While the information on this site is based on official statistical data, we do not guarantee its accuracy, completeness, or currency.
  • Price information is for reference only and may differ from actual market or retail prices. Please do not use this data as the sole basis for investment or trading decisions.
  • Nutritional data is based on official Japanese food composition tables, but actual values vary by variety, region, and preparation method. Do not use this as a substitute for medical or nutritional advice.
  • The site operator accepts no responsibility for any damages arising from the use of this site.

5. Design Principle

Produce choices are shaped by more than one factor. Price alone is not enough, and neither is nutrition alone.

Minolier aims to place seasonality, origin, price, and nutrition side by side so the information is quick to scan and practical to use.
