Japanese Mirin Explained: Hon Mirin vs Mirin-Style vs Fermented Seasoning
Mirin was confusing to me too at first because three bottles can sit together and all look like “sweet cooking seasoning.” The alcohol and salt differences make them much easier to understand.
Hon mirin, mirin-style and mirin-type seasoning are not the same product.
Kikkoman distinguishes them by production method, alcohol content and whether salt is added.
Three bottles, three legal/product categories
Kikkoman describes hon mirin at about 14% alcohol with no added salt, mirin-style seasoning at under 1% alcohol with no salt, and fermented mirin-type seasoning at about 11% alcohol with salt added.
Alcoholic beverage category; no added salt in Kikkoman's comparison.
Very low alcohol; produced as a seasoning.
Fermented seasoning with salt added to make it non-beverage.
If a Japanese recipe says “mirin,” it often means hon mirin. Mirin-style seasoning and fermented mirin-type seasoning can behave differently in flavor and salt balance.
Hon mirin
Kikkoman describes hon mirin as a liquor made from ingredients such as glutinous rice, rice koji and shochu or other alcohol. It is about 14% alcohol and contains no added salt in Kikkoman's comparison.
Mirin-style seasoning
This category keeps alcohol below 1% and is produced mainly by blending sugars and other ingredients rather than the same maturation process as hon mirin.
Fermented mirin-type seasoning
This has alcohol like hon mirin but includes salt so it is treated as a non-beverage seasoning. Kikkoman notes that you may need to adjust salt in the dish.
This is a tiny label difference that changes a recipe more than you expect. If I am following a Japanese recipe closely, I check whether the bottle actually says 本みりん.
Why mirin matters in cooking
MAFF and Kikkoman describe mirin as contributing sweetness, gloss and other cooking effects in Japanese dishes.

Bottom line
Look for 本みりん when you want true hon mirin, and remember that mirin-type fermented seasoning can add salt that hon mirin does not.
