Overview
This is a classic Edo-period Ko-Imari porcelain soba choko (buckwheat noodle dipping cup), decorated in underglaze cobalt blue (sometsuke). It features bold geometric borders alongside medallion reserves (marumon) containing geometric tortoiseshell (kikkō) and landscape motifs, reflecting the sophisticated graphic sensibilities of Edo urban culture.
Story
During Japan's peaceful Edo period, street stalls serving buckwheat soba noodles exploded in popularity across towns like Edo (Tokyo). Potters in Arita mass-produced these sturdy, hand-painted porcelain cups, turning everyday dining utensils into canvas-like showcases of bold design.
Maker / Origin
Rather than individual art stars, these pieces were crafted in workshop kilns across the Arita/Hizen region using high-temperature porcelain techniques originally adapted from Korean artisans. Master painters applied cobalt blue directly to the raw porcelain body using swift, confident brushwork honed over generations.
Condition & Value
Appears to be in good antique condition with rich cobalt tones. Typical minor glaze imperfections and firing flaws common to Edo wood-fired kilns are expected; condition significantly impacts final market valuation.
