A distiller at the southern tip of the Satsuma Peninsula.

Satsuma Shiranami is the flagship sweet-potato shochu of Satsuma Shuzo, a distiller in Makurazaki, near the southern tip of the Satsuma Peninsula in Kagoshima Prefecture. The company’s own history says it was established in June 1936 as Satsuma Gōdō Shusei and took the name Satsuma Shuzo in May 1949. “Satsuma” is the name of the former province in which Makurazaki lies; shiranami means “white waves.”

The company is not a stand-alone family firm. Japanese Wikipedia describes it as sharing its roots with Hombo Shuzo and Hombo Shoten, and as one of the core companies of the Hombo group; Hombo Shuzo also owns the Mars Shinshu whisky distillery in Nagano. The company website names Yoshimoto Yoshihisa as president.

Its plants are all in southern Kagoshima, the company says: the Kedogawa distillery beside its Makurazaki head office, the Ei distillery in Minamikyushu, opened in October 1980, the Hinokami distillery in Makurazaki, opened in October 1975, and a bottling plant in the town. In October 1992 it opened a museum-cum-distillery called Meijigura, the “Meiji storehouse,” at Kedogawa, where it says craftsmen still make shochu in clay pots that visitors can watch; a beer house followed in 1997. In December 2022 Hinokami received a whisky licence, and the company began distilling malt whisky there in February 2023 and grain whisky in December 2023; a visitor centre opened in January 2026.

Six parts shochu, four parts hot water.

The company describes Satsuma Shiranami as an imo shochu made from Kagoshima-grown sweet potatoes and rice koji using methods handed down from the Kurose tōji, master brewers of the Satsuma tradition. Kuro Shiranami is its black-koji version, and Japanese Wikipedia says Sakura Shiranami was released to mark the full opening of the Kyushu Shinkansen. The brand’s age is given by anniversary: the trade paper Nihon Shokuryo Shimbun reported in October 2025 that Satsuma Shiranami had reached 70 years on sale, and the magazine DIME called it a 66-year-old brand in April 2021.

Its fame rests on a way of drinking it. Japanese Wikipedia says that national television advertising in the late 1970s, with the lines “6×4 (rokuyon) no oyuwari” — six parts shochu to four of hot water — and “yoizame sawayaka,” roughly “fresh as you sober up,” made the Shiranami name known across Japan and helped set off the shochu boom of the 1980s; DIME wrote in 2021 that the “rokuyon” catchphrase had spread the company’s name through television commercials. The company still teaches the ratio on its “Oyuwari Laboratory” website, which explains that a 25 percent shochu mixed six to four comes out at about 15 percent, and advises pouring the hot water first and the shochu second.

Japanese Wikipedia lists a long line of advertising faces, with the actor Mikuni Rentarō as a long-standing image character for Satsuma Shiranami, and later Yakusho Kōji, Tamayama Tetsuji for Kuro Shiranami and, in 2015, Yonekura Ryōko. In February 2017, the advertising trade site AdverTimes reported, the company released “Kono chikyū no hibi-tachi e,” a Shiranami commercial directed by the film-maker Lee Sang-il, created by BLUEandGREEN, Dentsu Kyushu and Dentsu Creative X, with Teshima Aoi covering Matsuda Seiko’s song “Ruriiro no Chikyū.” The company’s current commercials, under the line “Fūdo no chikara,” “the power of the land,” include versions titled Bordeaux and Scotland. Japanese Wikipedia also records a neon sign at Tokyo’s Ikebukuro Station and praise for the shochu from the film director Itami Jūzō in his essay collection Futatabi onnatachi yo!; in February 2021, DIME reported, the company put Satsuma Shiranami, Kuro Shiranami and Sakura Shiranami into small bottles.

Shochu, sweet potatoes and southern Kyushu.

The seven brands in this group are Japanese shochu and awamori names: Kurokirishima, Satsuma Shiranami, Mitake, Mori Izo, Kannoko, Zuisen and Kumesen. Shochu is Japan’s native distilled spirit, and Japanese Wikipedia describes it by its main ingredient: sweet potato, barley, rice, buckwheat or brown sugar among others. Sweet-potato, or imo, shochu is made mainly in Kagoshima and Miyazaki in southern Kyushu, and in Kagoshima it is registered under the geographical indication “Satsuma shochu.” Barley, or mugi, shochu is made widely, including in Oita, home of iichiko. Awamori is the spirit of the Ryukyu Islands: made from rice with black koji and distilled once in a pot still, and called kusu when it has been stored for three years or more.

The makers are mostly regional companies tied to a single town. Kurokirishima comes from Kirishima Shuzo of Miyakonojo in Miyazaki, whose origins Japanese Wikipedia dates to 1916. Satsuma Shiranami and the oak-aged barley shochu Kannoko are both made by Satsuma Shuzo of Makurazaki, at the southern tip of the Satsuma Peninsula. Mitake is made on the island of Yakushima by Mitake Shuzo, which began there in 1958; Mori Izo is made by Mori Izo Shuzo in Tarumizu, Kagoshima. In Okinawa, Zuisen Shuzo has made awamori in Shuri, now part of Naha, since 1887, and Kumesen is an Okinawan awamori name.

Each guide separates what independent sources record from what the company says about itself — its founding story, its owners over time, where its shochu or awamori is made and how its labels and bottles have changed — and marks plainly what rests only on the company’s own word.

A 1970s label, brought back for the 70th year.

The brand has lately looked back at its own past. For the 70th anniversary in 2025 the company ran a prize campaign with a dedicated 70th-anniversary logo, Nihon Shokuryo Shimbun reported, offering a revival Satsuma Shiranami that recreated the taste of the 1970s. On 5 October 2026 it began shipping that revival, Fukkoku Satsuma Shiranami, nationwide in limited quantities; the company says it reproduces both the taste and the package of the 1970s, and that it was developed by interviewing former employees who had made the shochu at the time.

Shiranami sits alongside other Satsuma Shuzo names with their own looks. The long-aged barley shochu Kannoko takes its name, the company says, from a spring near Makurazaki, and its bottle follows the kompura bottles of Hasami in Nagasaki, in which Japanese sake and soy sauce were shipped to Europe through the Dutch East India Company. Since 2023 it has also distilled whisky at Hinokami, released under the HINOKAMI name. Each autumn it releases a new-season Satsuma Shiranami Shinshu, a tradition it says it revived in 1990.

For a design guide, Satsuma Shiranami shows how a shochu brand can be identified as much by a ritual — six to four, hot water first — as by a label, and how a 1970s package can return as an anniversary piece. Compare Kurokirishima, the black-koji shochu from Miyakonojo just across the Miyazaki border, and Kannoko, its sister barley shochu. For this guide we use a southern-sea indigo, white and a sweet-potato red with a serif, an unofficial interpretation; no product or logo is reproduced.
