The Japanese Highball is whisky and soda taken seriously. The drink is whisky-and-soda anywhere in the world; what makes the Japanese version distinct is a set of bartender protocols that have hardened into a tradition since the 1950s: glass and ice pre-chilled in the freezer; large clear ice cubes that won't dilute too fast; a 1-to-3 or 1-to-4 ratio that's lighter than the American whiskey highball; a thirteen-and-a-half-turn stir that mixes without overaerating the soda.
The whisky goes in first. The soda goes in second. The stir is thirteen and a half turns. Anything else is a different drink.
Suntory and the Birth of the Format
Suntory, Japan's first whisky distillery (founded 1923, first whisky 1929), built its post-war marketing around the highball. The drink offered an entry point into whisky for a domestic market that had never grown up on the spirit; the company's bartender schools standardized the serving protocol in the 1950s. The thirteen-and-a-half-turn stir and the pre-chilled glass became Suntory company doctrine, then bartender lore, then a defining cultural object.
By the 2010s the Japanese Highball had crossed into American bartending — first at specialty Japanese-style bars in New York and Los Angeles, then more broadly as a default lighter cocktail. The technique transfers; the regional Japanese whisky doesn't, since most Japanese whisky is now in tight allocation. The drink survives the substitution.
The Spec
An ounce and a half of Japanese whisky in a pre-chilled highball glass filled with large clear ice cubes, topped with four and a half ounces of cold sparkling water (Suntory's Premium Soda or any premium club soda). A long stir — Suntory's protocol is thirteen and a half rotations — and a lemon peel expressed over the surface. No garnish past the peel oils.
Pre-Chilling Everything
The glass goes into the freezer for at least ten minutes — long enough that it frosts on the outside. The ice cubes are large, clear, and from the freezer compartment (not the ice machine's cloudy hollow cubes). The whisky pours from a bottle that's been on the bar at room temperature. Soda from the fridge or, ideally, just out of the soda siphon. Every ingredient cold; nothing waiting.
Japanese Whisky Choice
Suntory's Toki, Hibiki Harmony, or the now-near-impossible Yamazaki are the obvious picks. Nikka From the Barrel (one of the few remaining widely available Japanese whiskies) works well — its higher proof stands up to the dilution. If you can't source genuine Japanese whisky, a Scotch single grain or a softer blended Scotch (Johnnie Walker Black, Famous Grouse) is the most defensible substitute.
The Stir, and the Pour Order
Whisky into the chilled glass first, then ice, then soda poured slowly down the side of the glass to preserve carbonation. Stir thirteen and a half rotations of a long bar spoon, cutting through the ice rather than around it. Don't shake; don't muddle. The thirteen and a half is exact, not approximate — Suntory teaches it that way, and the precision is part of the cultural object.
Bottom Line
The Japanese Highball is the standard for what a session highball can be. It rewards careful technique without requiring rare ingredients; it scales from one drink at home to fifty drinks in service; it is built to be ordered three times in a sitting without overwhelming the drinker. If you've been making whisky-and-sodas a different way, try one Suntory-style and see if the protocol earns its precision.
