Special Designation Sake: The 8 Official Types Explained
By Dr. Sake
Special designation sake — tokutei meisho-shu (特定名称酒) — is a legal classification of eight sake styles defined by Japan’s National Tax Agency labelling standards for sake (in Japanese), based on three measurable criteria: how much the rice is polished, whether distilled brewing alcohol is added and in what amount, and how much of the rice is turned into koji. It is not a ranking of quality. A bottle labeled junmai is not automatically “lower” than one labeled daiginjo — the two words describe different production choices, not different scores. Any sake that doesn’t meet one of these eight rule sets is simply futsū-shu, or regular sake, which still accounts for the bulk of what Japan drinks daily.
What Is Special Designation Sake?
Special designation sake is the set of eight categories the NTA created in 1989 (revised in 2003, effective 2004, and again in 2022, effective 2023) to standardize how brewers describe their sake’s method and ingredients on the label. Before this system, terms like ginjo or junmai were used loosely across the industry. The NTA’s Seishu no Seihō Hinshitsu Hyōji Kijun (“Standards for Labeling the Manufacturing Method and Quality of Sake”) fixed exact thresholds so a label claim can be checked against a rule, not a brewer’s marketing instinct.
The eight names split into two families based on ingredients:
- With brewing alcohol added: honjozo, tokubetsu honjozo, ginjo, daiginjo
- Rice, koji, and water only (junmai family): junmai, tokubetsu junmai, junmai ginjo, junmai daiginjo
What Are the 8 Types of Special Designation Sake? (Comparison Table)
The eight designations are separated by seimaibuai (rice polishing ratio), whether brewing alcohol is used, and sensory/labeling requirements. Every one of the eight also requires a minimum koji-rice ratio of 15% of the total rice used — a rule the NTA added in 2003, effective from 2004, specifically to tighten the standard.
| Designation | Raw Materials | Seimaibuai (Polishing Ratio) | Koji-Rice Ratio | Sensory / Labeling Requirement |
|---|---|---|---|---|
| Junmai Daiginjo | Rice, koji, water | 50% or less | 15% or more | Ginjo-style brewing; distinctive aroma and especially good color/clarity |
| Daiginjo | Rice, koji, water, brewing alcohol | 50% or less | 15% or more | Ginjo-style brewing; distinctive aroma and especially good color/clarity |
| Junmai Ginjo | Rice, koji, water | 60% or less | 15% or more | Ginjo-style brewing; distinctive aroma and good color/clarity |
| Ginjo | Rice, koji, water, brewing alcohol | 60% or less | 15% or more | Ginjo-style brewing; distinctive aroma and good color/clarity |
| Tokubetsu Junmai | Rice, koji, water | 60% or less, or a stated special method | 15% or more | Especially good aroma and color/clarity; special method must be explained on label |
| Junmai | Rice, koji, water | No fixed threshold | 15% or more | Good aroma and color/clarity |
| Tokubetsu Honjozo | Rice, koji, water, brewing alcohol | 60% or less, or a stated special method | 15% or more | Especially good aroma and color/clarity; special method must be explained on label |
| Honjozo | Rice, koji, water, brewing alcohol | 70% or less | 15% or more | Good aroma and color/clarity |
Seimaibuai is the percentage of the original brown rice grain that remains after polishing — a seimaibuai of 60% means 40% of the outer grain has been milled away. Anything that falls short of one of these eight rule sets — for example, sake made with more than 10% added alcohol, or rice polished less than 70% without meeting another category’s terms — is labeled futsū-shu (regular sake), which is still what most sake consumed in Japan actually is.

What Does Seimaibuai (Rice Polishing Ratio) Actually Control?
Seimaibuai controls how much of the rice grain’s outer layer — where fats, proteins, and minerals concentrate — is removed before brewing. The NTA defines it as the weight of the milled (white) rice divided by the weight of the original brown rice. A lower number means more polishing: daiginjo and junmai daiginjo require 50% or less, meaning at least half the grain is milled away before fermentation even starts. Polishing further tends to produce a lighter, more fragrant sake because it strips away the compounds that produce heavier, earthier flavors — but this is a brewing choice tied to a target style, not a universal improvement. Junmai carries no fixed seimaibuai requirement at all under current NTA rules; this threshold (previously 70%) was removed in a 2003 revision specifically so brewers of unpolished-forward junmai styles weren’t boxed out of the category.
What’s the Difference Between Junmai and Non-Junmai Designations?
The core difference is whether distilled brewing alcohol (jōzō arukōru) is added, and junmai styles never allow it. The four “junmai family” designations — junmai, tokubetsu junmai, junmai ginjo, junmai daiginjo — are made from rice, koji, and water only. The other four — honjozo, tokubetsu honjozo, ginjo, daiginjo — permit a small addition of distilled brewing alcohol, capped by NTA standard at roughly 10% of the white rice’s weight (commonly cited in the industry as up to 120 liters of alcohol per ton of milled rice). This addition is a technique, not a shortcut: brewers use it to lighten body, sharpen aromatics, and stabilize certain yeast-driven fragrances, a practice with its own long technical history in Japanese brewing rather than a substitute for quality rice or careful fermentation.
Is Special Designation Sake a Quality Ranking?
No — special designation sake classifies production method and ingredient choices, not quality. This is the single most common misunderstanding about the system, and it’s worth stating plainly: the NTA’s eight categories were built to answer “how was this made,” not “how good is this.” A well-made honjozo can be more refined, balanced, and enjoyable than a poorly made daiginjo, and a skilled brewer’s junmai can easily outshine another brewery’s junmai ginjo. Seimaibuai, alcohol addition, and koji ratio describe process; they say nothing about the skill of the toji (master brewer), the quality of the water, the yeast strain, or the fermentation management — the variables that actually decide how a sake tastes in the glass.
An independent view worth holding onto: sommeliers and kikisake-shi (certified sake tasters) who train professionally are taught early to treat the eight designations as a map of technique, not a scoreboard — the same caution wine professionals apply when they remind people that “reserve” or “estate” labels describe rules of production, not a guaranteed hierarchy of taste.
This is also a useful moment to correct a common misconception carried over from wine: many drinkers assume more polishing (a lower seimaibuai number) is automatically “better,” in the same way some assume an unfiltered or “natural” wine is automatically more authentic. Neither assumption holds up. Wine and sake are shaped by dozens of interacting choices — rice variety, water source, yeast, temperature control, aging — and a classification label captures only a few of them. Sake’s eight designations, like wine’s regional or estate classifications, are tools for understanding method; they were never meant to replace tasting.
What Is Futsu-shu, and Why Isn’t It “Lower Quality”?
Futsū-shu is any sake that doesn’t meet the criteria for one of the eight special designations, and the label itself carries no formal quality claim either way. In practice, futsū-shu can be brewed with rice polished well beyond 70%, with alcohol added above the 10% threshold, or without meeting the 15% koji-rice minimum — any one of these disqualifies it from special designation status regardless of how carefully it’s made. Because futsū-shu isn’t required to disclose seimaibuai or ingredient ratios the way special designation sake is, it’s harder for a shopper to evaluate from the label alone, but that’s a labeling difference, not a verdict on the sake inside the bottle.
FAQ
Are junmai daiginjo and daiginjo made the same way except for alcohol?
Yes — both require a seimaibuai of 50% or less and ginjo-style brewing with a 15%-or-more koji-rice ratio; the only structural difference the NTA defines between them is that daiginjo permits added brewing alcohol (within the 10% cap) and junmai daiginjo does not.
Does a lower seimaibuai always mean a better sake?
No — seimaibuai indicates how much rice was polished, which affects style (typically lighter, more aromatic as polishing increases), but the NTA’s criteria don’t evaluate skill, water, yeast, or fermentation, all of which shape final quality independently of the polishing number.
What’s the difference between honjozo and tokubetsu honjozo?
Honjozo requires a seimaibuai of 70% or less; tokubetsu (“special”) honjozo requires either 60% or less, or another clearly explained special production method disclosed on the label, alongside an especially good aroma and color/clarity standard.
Can a sake be both ginjo and junmai?
Yes — junmai ginjo is exactly this combination: rice, koji, and water only (no added alcohol), brewed ginjo-style with a seimaibuai of 60% or less.
Is futsu-shu inferior to special designation sake?
Not by definition — futsū-shu simply doesn’t meet one or more of the NTA’s specific criteria (polishing ratio, added-alcohol limit, or koji-rice ratio), which is a labeling distinction rather than a measure of the sake’s craftsmanship or taste.
