How to read this table
Price per gram is the only number that lets you compare products across different package sizes. A $28 tin of 30g and a $45 bag of 100g look very different on the shelf; at $0.93/g and $0.45/g they tell a different story. Every price here is converted to USD at dated exchange rates and divided by the listed weight.
The market percentiles (p10, p50, p90) are computed from the full dataset of pure matcha powder products. A product above the market p90 is in the most expensive tenth of the entire market. A product below the market p10 is in the cheapest tenth.
Color coding: green values are above the market median; they are not necessarily better, just dearer. Values in the normal color are below the market median.
Method and limitations
Data. 150 pure matcha powder products from Shogyokuen with a listed price and package weight. Accessories, bundles, sweetened blends, and non-matcha listings were removed. Prices converted to USD at dated rates.
Market. Market percentiles are computed from the full dataset of pure matcha powder products across all brands. The p10 is the 10th percentile (cheapest tenth), p50 is the median, p90 is the 90th percentile (dearest tenth).
Caveats. Prices are point-in-time observations. Sale prices, subscription discounts, and bundle pricing are included when observed. Currency conversion introduces small error at the margins.
