Takanotsume Pepper

Takanotsume is a Japanese C. annuum landrace whose name literally means “hawk’s claw”, referring to the sharply pointed, claw-like fruit. Academic work describes the plant as indeterminate with a spreading branching habit and thin-fleshed fruit that became popular for spice use partly because the pods lose water quickly after harvest. In a peer-reviewed study, mature fruit averaged about 3.8 cm long and 0.6 cm wide, with dark red mature colour and a warm, herbaceous aroma.

Historically, it was already established in Japan by the Edo period and is recorded in Hiraga Gennai's Banshoufu. Modern Japanese research and institutional sources treat it as one of Japan’s representative chilli landraces. A preserved pure line, Sakai Takanotsume, has been maintained in Osaka for about 120 years and is now recognised as a traditional vegetable there, which shows that at least one old Takanotsume lineage remained culturally important and locally preserved.

One important point of conflict does show up in the sources. Older descriptions and recent genetic work describe traditional Takanotsume as a small, upright, single-fruiting type, but many current commercial “Takanotsume” lines are cluster-fruiting and longer, around 5.5 to 6.0 cm in the Japanese accession study. So the name is being used a bit loosely in modern seed trade, and not every plant sold as Takanotsume seems to match the older form.

There is also a real heat conflict online. A peer-reviewed chemical analysis gave 11,900 ± 720 SHU, while commercial listings often claim much higher figures such as 30,000 or 100,000 SHU. I used 11900 because it is the strongest directly measured figure I found.
