Wakocha (Japanese Black)

Wakocha is Japanese black tea, made by fully oxidizing leaf from a country whose tea industry is built almost entirely around green tea. Because most of it comes from green-tea cultivars, classic wakocha tends to be gentle, mild and naturally sweet with very low astringency, though purpose-bred black-tea cultivars push it richer. The variable that matters most is cultivar: a green-tea cultivar like Yabukita gives a soft cup, while Benifuki gives a bolder, more conventionally black one.
Wakocha's defining trait is gentleness: a mild, soft, naturally sweet cup with notably low astringency, a world away from a brisk Assam. Cultivar is the main quality lever, so it helps to know what you have: Yabukita and other green-tea cultivars give a delicate, mellow tea, while Benifuki and Benihikari were bred for black tea and give more body, color and aromatic punch. Look for neat, well-rolled leaf and the clean, precise processing Japanese tea is known for, with a sweet, sometimes fruity or lightly malty profile. Because Japan's black-tea output is small and often artisanal, expect higher prices than commodity black tea and judge by craft rather than strength. A thin, papery or sour cup is a sign of careless oxidation rather than the style working as intended.
Wakocha is produced across Japan's tea regions, including Kagoshima, Shizuoka, Kyushu and Uji, generally as a small-batch alternative to the dominant green tea. Most of it uses cultivars selected for green tea (above all Yabukita), which is exactly why the classic style is so mild. Cultivars such as Benifuki and Benihikari, which carry assamica heritage and were developed with black tea in mind, are the exception and yield a richer, more astringent and more aromatic cup.
Western: 3 g per 200 ml, 85 to 90°C (cooler than a typical black tea to protect the delicate sweetness), 2.5 to 3 minutes. Gongfu also works well: 4 to 5 g per 100 ml, 85 to 90°C, around 20 seconds for the first steep, ascending. Wakocha rarely needs or wants fully boiling water, and milk tends to bury its gentle character.
Wakocha runs roughly €15-35 (about $16-38) per 100 g, reflecting small-scale Japanese production. Single-cultivar and craft lots from named growers reach €40-70 (about $43-76) per 100 g.

Korean Black (Hongcha)
The closest regional parallel: Korean black tea is likewise made in a green-tea country from green-tea-leaning material, and shares wakocha's gentle, sweet, low-astringency character.
Sencha
The green default from the same cultivars and gardens; tasting wakocha beside sencha shows what full oxidation does to a leaf otherwise destined to be green.
Dianhong (Yunnan)
A useful contrast in gentle black teas: dianhong is soft and honeyed but unmistakably assamica and malty, while wakocha is lighter and more delicate again.
Japan actually produced black tea for export in the late nineteenth and early twentieth centuries before green tea fully dominated, and the cultivar Benifuki, now prized for wakocha, is also studied for its unusually high level of methylated catechins.
