Where the Name "Green Tea" Came From

In English, green tea is a category term covering all unoxidized tea. It has nothing to do with sweetness.

Its use in Japan for a sweet powdered drink dates to the twentieth century.

An era that valued imported-sounding names

Through the mid-1950s to 1970s, household refrigeration spread and demand for cold drinks grew. Sweet matcha beverages became popular in that period.

Calling the product guriin tii rather than sweetened matcha reflected the moment. A katakana loanword signaled novelty and sophistication — useful for something sold in cafés.

The resulting mismatch

Japanese retail settled on one meaning while English kept another.

• Someone from abroad says they like green tea; they are served a sweet powder, and the conversation diverges
• A visitor buys "green tea" in a Japanese supermarket and is surprised by the sweetness
• The idea of sugar in green tea does not translate readily

Matcha now travels on its own

Matcha has become widely recognized internationally. Green powder mixed into liquid — the concept carries.

But matcha lattes abroad typically contain sugar by default, and ordering one unsweetened requires saying so. In that sense, overseas matcha occupies something close to the position of green tea in Japan.

Terms shift when they cross languages.

Product naming today

More specific names are increasingly common: sweetened matcha, matcha milk, Uji green tea.

As the general term became less reliable, labeling moved toward explanation.

For export

Sweetened matcha or matcha with sugar communicates accurately. Green tea alone reads as unsweetened leaf tea.
