Japan’s liquor tax reform of 1 October 2026 is being reported almost entirely as “beer gets cheaper”. On the same day, chu-hai, sours and canned highballs go up. The tax on a 350ml can rises from ¥28 to ¥35. Beer-type drinks have been re-rated in three stages since 2020; for chu-hai, this is the first increase ever. Below: a calculator that turns your drinking habit into an annual figure, the “10-degree cliff” that explains why no canned chu-hai goes above 9% ABV, and whether stocking up before October is worth it.
· Chu-hai, sours and canned highballs (sparkling drinks under 10% ABV): ¥28 → ¥35 per 350ml can, ¥40 → ¥50 per 500ml can
· One 350ml can a day works out to roughly ¥2,600 more per year (about ¥2,800 with consumption tax)
· The tax gap against beer nearly halves, from ¥35.35 to ¥19.25
· Stocking up barely helps: a floor-stock tax applies to distribution inventory on the day of the change
What changes: ¥28 to ¥35 per 350ml can
Under the Liquor Tax Act, most chu-hai, sours and canned highballs fall into a category called “other sparkling liquors”, defined as drinks other than beer and happoshu that are under 10 degrees of alcohol and sparkling. The rate on that category rises from ¥80,000 to ¥100,000 per kilolitre on 1 October 2026[NTA].
| Category | Until Sept 2026 | From Oct 2026 | Per 350ml can |
|---|---|---|---|
| Beer | ¥181,000/kL (¥63.35) | ¥155,000/kL (¥54.25) | −¥9.10 |
| Happoshu (under 25% malt) and “new genre” | ¥134,250/kL (¥46.99) | ¥155,000/kL (¥54.25) | +¥7.26 |
| Other sparkling liquors (chu-hai, sours, canned highballs) | ¥80,000/kL (¥28) | ¥100,000/kL (¥35) | +¥7.00 |
This is the final stage of a phased alignment decided in the FY2017 tax reform. Where similar drinks carry different tax rates, product development bends toward whichever category is taxed least; the reform sets out to correct that on a revenue-neutral basis[MOF]. The unification of the three beer categories is covered in the 2026 beer tax reform.
Calculator: what your drinking adds up to
Pick a can size and how many you drink per week. The tool shows the change in annual liquor tax, plus what the same number of beers would cost in tax after the reform.
Note: the figures are liquor tax only. Shelf prices also move with ingredient and logistics costs and each maker’s pricing decisions.
The gap against beer halves, from ¥35 to ¥19
The bigger story is not the amount but the narrowing gap.
| Liquor tax gap per 350ml can | Before | After |
|---|---|---|
| Beer minus chu-hai | ¥35.35 | ¥19.25 |
| “New genre” minus chu-hai | ¥18.99 | ¥19.25 |
The beer-to-chu-hai gap roughly halves, while the gap between “new genre” (third-category beer) and chu-hai barely moves. So the reform does little to the “happoshu and new genre to chu-hai” trade-down, and a lot to the distance between chu-hai and real beer. Beer falls ¥9.10 a can while chu-hai rises ¥7.00, closing the gap by ¥16.10 in tax terms. Price parity does not arrive, but “chu-hai because it is cheaper” becomes a weaker argument.
Why “strong” cans stop at 9%: the 10-degree cliff
Walk the chu-hai shelf and you will see 3%, 5%, 7% and 9% — and almost nothing at 10% or above. That is not a coincidence; it is where the tax category changes.
To count as “other sparkling liquors” a drink must be under 10 degrees of alcohol. At 10 degrees or above it leaves the category and is taxed by what it actually is — as a liqueur (¥120,000/kL under 13 degrees, or ¥42 per 350ml) or as spirits (¥200,000/kL under 21 degrees, or ¥70)[NTA].
A 9-degree can pays ¥28 per 350ml (¥35 after the reform). Push it to 10 degrees and, as a liqueur, it jumps to ¥42 — a 50% increase in tax for one extra degree. That is why makers stop at 9%.
There is a special measure that caps the rate on low-alcohol spirits and liqueurs at ¥80,000/kL, but it applies only to non-sparkling drinks, so a carbonated can cannot use it.
What is interesting is that the reform halves this cliff. Before, 9 degrees (¥28) and 10 degrees (¥42) were ¥14 apart; after, ¥35 and ¥42 are ¥7 apart. The tax brake gets weaker.
The market, however, is moving the other way. The Ministry of Health, Labour and Welfare’s drinking guideline of February 2024 puts the level at which lifestyle-disease risk rises at 40g of pure alcohol per day for men and 20g for women[MHLW]. A 500ml can at 9% contains about 36g. Following the guideline, major brewers have said they will stop launching canned chu-hai at 8% or above. The tax brake loosens as the health brake tightens.
Is it worth stocking up before October?
Less than you would think, for two reasons.
One: distribution inventory is taxed too
Liquor tax is normally levied when goods leave the production site, so in principle stock shipped in September keeps the old rate. But when rates change, inventory held in the distribution chain at midnight on the day of the change is adjusted for the difference — a floor-stock tax where rates rise, and a floor-stock refund where they fall. The filing deadline for the 1 October 2026 adjustment is 2 November 2026[NTA]. So cheap old-rate stock will not sit on shelves for long. Beer, conversely, qualifies for the refund, removing one reason for price cuts to lag.
Two: the amount is small and cans expire
You save ¥7 of tax per 350ml can (about ¥7.7 with consumption tax). A 24-can case works out to roughly ¥185. Best-before dates vary by product and are printed on the can. Buying several cases to save that much rarely adds up.
The bigger win is changing how you buy after October. With beer down ¥9.10 and chu-hai up ¥7.00, anyone who has been choosing chu-hai on price should compare the shelf tags again.
Frequently asked questions
How much more will chu-hai cost from October 2026?
The liquor tax rises by ¥7 on a 350ml can (¥28 to ¥35) and by ¥10 on a 500ml can (¥40 to ¥50). Including 10% consumption tax, the upward pressure on a 350ml can is about ¥7.7. Actual shelf prices also depend on ingredient costs and each maker’s pricing.
Are canned highballs affected too?
Yes. Even though they are whisky-based, a canned highball that is under 10 degrees of alcohol and sparkling falls into “other sparkling liquors” and is taxed like chu-hai. Most sit around 7%, so a 350ml can rises by ¥7.
Why are there so few canned chu-hai above 10%?
At 10 degrees or above the drink leaves the “other sparkling liquors” category and is taxed as a liqueur (¥42 per 350ml) or as spirits (¥70). Staying at 9% keeps the tax low. The October 2026 reform narrows that gap from ¥14 to ¥7, but makers are separately scaling back high-alcohol products following the health guideline.
Will buying in September save money?
Only marginally. Inventory in the distribution chain at midnight on 1 October is adjusted through the floor-stock tax, so old-rate stock does not linger. And the difference is about ¥7 a can, roughly ¥185 for a 24-can case.
Do sake and wine rates change too?
No. The October 2026 reform covers sparkling liquors (beer, happoshu, new genre and other sparkling liquors) and the special rate for low-alcohol spirits and liqueurs. Sake and fruit wine were already aligned at ¥100,000/kL in the October 2023 reform and are unchanged.
