Ginger beer, tall over ice. Daidai (bitter orange) with it.
The distilleries themselves now sell imo shochu as a highball. Soda lifts the aroma off the glass instead of burying it.
One part shochu to three or four parts mixer, over plenty of ice. If it tastes thin, go two to three next time.

What to mix with it
Tap a family to narrow it down. Every suggestion carries its reasoning, so if the reasoning does not convince you, ignore the suggestion.
Bitter orange: sour and aromatic rather than sweet, the citrus that goes into ponzu. Bottled juice is sold for cooking and works straight in a glass. Use the peel too, it carries most of the smell.
Citrus acid is what cuts sweet potato's weight, which is why Kagoshima bars pour imo shochu with grapefruit and yuzu before anything else.
There is real sugar in this bottle already, and acid is what keeps it from reading as syrup.
Daidai is the citrus in ponzu, and ponzu is already on the table next to imo shochu
The peel is doing what the orange twist on an old fashioned does
A Miyazaki citrus eaten with the white pith left on, which is sweet rather than bitter. Gentler and more floral than lemon, so it flavours a drink without taking it over.

A Miyazaki citrus and a Miyazaki spirit, which is usually all the reason a pairing needs
Softer acid than lemon, so the rice sweetness stays in the glass
Soft water, cold, over ice or not. One to one is normal. Mix a day ahead (maewari) and the edges round off.
Hot water is the Kagoshima serve and it earns its reputation: heat pulls the earth and the sweetness up out of the glass. Cold water does the opposite and lengthens it without changing its shape.
Rice shochu mizuwari is a dinner drink in Kumamoto
Maewari: mix imo shochu and water a day ahead and it rounds out
Sakamoto's, fermented outdoors in earthenware jars in Fukuyama and aged at least a year; Toiro and Japanese Taste ship it in the US. A teaspoon in a mizuwari is the whole intervention, and a second one is usually a mistake.
There is real sugar in this bottle already, and acid is what keeps it from reading as syrup.
Umeboshi in hot shochu is a Kagoshima winter, and salt is the fastest way to make an earthy bottle taste like more of itself.
Black vinegar is rice fermented with koji and then soured, so it is the same mould arriving a second time
Eden Foods sells it as Ume Plum Vinegar in most US supermarkets, and it is one of the cheapest things on this list. A bar spoon, and unlike a crushed umeboshi it can go into a shaken drink.

Salt and lactic acid land on the sweetness koji leaves behind
Okinawa's own citrus, picked green and sharp, more bitter than lime and more floral than sudachi. Squeezed over awamori and soda it is what the islands actually drink.

Hot water in the glass first, spirit poured on top so it mixes itself. Around 40C in the glass is the sweet spot. This is not the only way, it is one way.
Hot water is the Kagoshima serve and it earns its reputation: heat pulls the earth and the sweetness up out of the glass. Cold water does the opposite and lengthens it without changing its shape.
Oyuwari: hot water first, then shochu, six to four. Imo shochu opens up in warmth
Hoppy Beverage Co. has made it in Tokyo since 1948; at 0.8 percent it is legally a soft drink, and it is hard to find outside Japan. Chill the bottle, the shochu and the mug and no ice is needed.
The distilleries themselves now sell imo shochu as a highball. Soda lifts the aroma off the glass instead of burying it.
An aged bottle is the one you would not lengthen with a beer substitute
Carbonation carries aroma up out of the glass, so a highball shows an aromatic bottle off rather than diluting the point of it.
One part shochu to five parts Hoppy lands near 4 percent and drinks like a pint with none of beer's body
Braulio, made in Bormio from gentian, juniper, peppermint and yarrow, around forty-five dollars. A summer drink on shochu and a winter one on whisky, which is one bottle behaving two ways.
Amaro and gentian answer the earth with more earth, which is why a split-base imo drink reads as intentional rather than odd.
Lustau or González Byass. Fino is salt and living flor; this is what is left after the flor dies, and at 18 percent an ounce lengthens the glass rather than strengthening it.
Both have spent years going quietly brown, and they meet in the middle
Cynar, 16.5 percent, which is weaker than the shochu itself, so equal parts lands near 20 percent and the drink stays long. Soda or a grapefruit soda over the top is the producer's own serve.
Amaro and gentian answer the earth with more earth, which is why a split-base imo drink reads as intentional rather than odd.
Small Hand Foods', or sugar, water and gum arabic from the baking aisle at home. Worth knowing that most Japanese gum syrup on a shelf today has no arabic gum in it at all.
A 25 percent spirit brings far less viscosity than a 40 percent one, so a shaken sour goes thin
The Japanese Bitters, five 100ml expressions, sold at Astor Wines in New York. Angostura at nearly 45 percent is a small spike in a 25 percent drink in a way these are not.
Amaro and gentian answer the earth with more earth, which is why a split-base imo drink reads as intentional rather than odd.
Hana Makgeolli is brewed in Greenpoint, Brooklyn; Makku sells a canned one. Strength varies widely across the category, from around 6 percent in a can to the mid teens for an unfiltered takju, so read the label before deciding how much to pour.
The yeasty haze gives back the body distillation took out
Cocchi Americano: moscato steeped with cinchona bark, gentian and bitter orange. Lillet dropped its quinine in 1985, so only the Americano side of the category still tastes of the bark, and equal parts with a shochu is about 21 percent.
Amaro and gentian answer the earth with more earth, which is why a split-base imo drink reads as intentional rather than odd.
Jack Rudy's Extra Bitter, made with real cinchona bark, or Small Hand Foods'. Half a teaspoon and soda, set to the bottle in front of you rather than to a tonic maker's idea of a spirit.
Amaro and gentian answer the earth with more earth, which is why a split-base imo drink reads as intentional rather than odd.
The Kyushu condiment, in a tube in any Japanese grocer: fermented yuzu peel, green chili and salt. A quarter teaspoon stirred into an oyuwari, which is the serve Asahi publishes.
Ginger and sweet potato are the same autumn kitchen. Heat gives an earthy bottle a pulse.
Unsweetened, four parts shochu to six parts soy milk, which is how the Japanese recipes write it. Stronger than it tastes, so pour it knowing that.
Milk and Calpis do soften imo shochu, and that is exactly the point for someone who thinks they dislike it. It is a gateway, not a destination.
Ways to serve it
On the rocks
Mizuwari (with water)
Sweet potato shochu is the one people are told they have to drink with hot water. Hot water is genuinely good, and it is also the hardest first sip to sell. Start it long and cold with soda and a wedge of grapefruit, and come back to the hot water once you like the spirit.
Cocktails other people made
Nobody has published a cocktail written for this exact bottle. These were written for other bottles, so each one says which, and what changes if you pour this instead.
