Vintage House of Koshu Flavored Sake Miniature Gift Set

This is a vintage Japanese novelty gift set from 'House of Koshu,' consisting of seven miniature glass bottles contained in their original cardboard display box. Each bottle is approximately 4-5 inches tall and crafted from frosted glass to resemble a stylized 'Kokeshi' doll, featuring a polished wooden head as a decorative cap. The labels are vibrant and paper-based, showing a rainbow motif and the brand name. The contents are identified as 'A Japanese Sake - Flavored Rainbow,' with specific flavors listed on bottom-tier bands including Reishu, Sumire, Banana, Mikan, Mizuiro, Sakura, and Midori. Each bottle contains a differently colored liquid corresponding to the label title. Produced in Japan and imported by Koshu Imports, Inc. of Los Angeles, California, this set likely dates to the mid-20th century (circa 1950s-1970s). The physical condition shows significant signs of age; the cardboard packaging is warped, stained, and torn in several places. The labels on the bottles are peeling at the edges, and there is evidence of evaporation or leakage, particularly in the darker-colored bottles. Despite these wear factors, the set remains a unique example of mid-century Japanese export marketing and kitsch design, retaining its original decorative wooden stoppers.
