The first gin released by Suntory, the name "Roku" is Japanese for "Six" which refers to the six Japanese botanicals used. Cherry blossoms, cherry leaves, green tea (sencha), refined green tea (gyokuro), sansho pepper, and yuzu are utilized along with eight other traditional gin botanicals. The LABEL 5 is printed with Japanese washi paper to highlight the meticulous Japanese craftmanship and nostalgia, with the bold calligraphy running across the LABEL 5 emphasizing the sentiment.
