01
The report in brief
From September 1 through October 5, our records show 37 sell-outs across 36 blends and 28 restocks across 25 blends. These are changes at a particular shop and package size, not market-wide stock changes. A blend can appear in both groups.
Of 439 comparable listings, 17 recorded a price-per-gram change above 5%: 14 rises and 3 falls. We compare the first September observation with the latest October observation, keeping the shop, package and currency fixed.

Shikibu no Mukashi at Kanso Tea (30g, USD): 1.67/g to 1.53/g, 8.0% down (September 5 to October 5).
Lower recorded prices do not prove a sale or a permanent reduction. Check the seller’s current pack and price before ordering.
06
Shops most often recorded in stock
Among shops with at least 5 tracked listings and checks on at least 3 dates, these tied for the highest recorded in-stock share. We show the largest check samples among the ties.
Nakamura Tokichi Official: 100.0% — 94 of 94 listing-day checks, covering 20 listings on 6 dates.
Ujicha Online: 100.0% — 80 of 80 listing-day checks, covering 16 listings on 5 dates.
Aiya Official Store: 100.0% — 69 of 69 listing-day checks, covering 13 listings on 6 dates.
Each shop has a different tracked product mix. These rates describe our records; they do not measure delivery reliability, guarantee stock today or establish overseas shipping.
07
What we counted
The window contains 2,687 saved stock checks. After matching listings we still track and keeping the final check per listing per UTC day, the report uses 2,637 observations across 576 listings, 448 blends and 92 shops. A listing is a blend at a shop in an exact package size.
Stock changes compare successive recorded states, including a previous check before September where available. Repeated changes count separately. Checks are intermittent, so the report cannot establish how long a tea was available between observations. Some saved statuses may be inferred when a page does not state stock clearly. The history does not identify those cases, so these are recorded statuses rather than independently confirmed availability.
08
Which price comparisons we left out
Prices use the recorded pack price divided by its weight. We require a positive price, matching stored per-gram arithmetic, a September and an October observation, and no currency change anywhere in the window. We use unambiguous single-pack gram labels; multipacks are left out. The threshold is strictly above 5%, before rounding.
The stock cohort includes 83 listings that switched recorded currency and 26 with pack labels outside that simple-weight rule. Those groups may overlap. Neither group is used for price comparisons.
We also held out Yutaka-no-Mukashi at Kyoto Antenna Shop Marutake Ebisu: its recorded 100g offer has a price matching the producer’s 40g offer. That could be a variant mismatch, so it is not reported as a discount. Matching labels alone cannot rule out every historical parsing error.
