Seven Stars Prime Leaf 8 (duty-free)

セブンスター・プライムリーフ・8・ボックス launched in April 2018 and is sold only in duty-free shops, nationwide in the sense that duty-free shops are nationwide. It is not a product you can buy in a Japanese tobacconist or from a vending machine.

The unusual thing about it is the format of sale: ¥4,500 buys 200 cigarettes, described as ten packs. That is the only Seven Stars product in this archive sold as a block rather than a single pack, and it is the reason the entry is worth making at all — a 12 mg cigarette at 200 per purchase exists nowhere else in the Japanese market.

Its blend is the domestic one with the charcoal filter, same as the rest of the brand, and its length follows the brand standard of 85 mm. This is the lower-yield of the two Prime Leaf products, at 8 mg and 0.7 mg — and 0.7 mg is the figure both this entry and the withdrawn 2014 menthol 8 box share, which is a coincidence of numbering rather than a relationship.

Availability is worth reading carefully rather than skimming. The product does not appear on JT’s current Seven Stars product page at all, and that page does not mention duty-free sales or the word used for them anywhere. Its existence, specifications, price and channel are documented here from ja.wikipedia’s current-products table, which is detailed on all four. That is a single reference for an entire entry, and it is flagged rather than presented as corroborated.

Rating

None yet. All three axes are zero, which the site reads as “not rated” rather than as a score of nought, so the rankings table shows a dash until somebody writes them.
