KAIBA, the supermarket-price market terminal
A Japanese-language dashboard tracks national reference prices for vegetables, eggs, and milk, with index readings and a store-price unit checker.
- For
- Japanese grocery shoppers comparing prices and food-market data
- Worth noticing
- Its 28-yen bean-sprout “index” is explicitly marked as fictional and excluded from real data and SPX calculations.
Field notes
The dashboard attributes its vegetable series to Japan’s Ministry of Agriculture, Forestry and Fisheries and displays ten items in yen per kilogram, marking potatoes and cucumbers unavailable for the shown week. SPX is described as a six-vegetable index normalized to a four-observation-week average of 100; the page separately compares item prices with the prior 13 observations. The egg-and-milk index remains uncalculated pending a defined baseline and comparison conditions.
