Usage Notes: Sift powder before use to prevent clumping; consume within one month after opening; drink immediately after preparation
Price: Not disclosed on any page found - no retailer with a live price was located for this specific product (Sazen Tea listing has no visible price and is out of stock; no other retailer product page for this exact SKU was found in search)
Name And Context: Described in general web coverage (not a dedicated page, drawn from search-result summaries referencing Yamamasa/Sazen material) as a koicha blend favored by Jimyousai iemoto, the 14th generation grand tea master of the Omotesenke school - one of several 'iemoto-favorite' ultra-premium Yamamasa Koyamaen blends alongside Otowa no Shiro and Suimei no Mukashi (which are attributed to a different, 15th-generation iemoto, Yuyusai).

Research notes

This was the hardest of the 14 to source: Yunomi, Rocky's Matcha, The Steeping Room, Kanso Tea, Ujichamatcha, and Zenplus searches did not surface a live product page for Hagami no Mukashi specifically (Ujichamatcha's guessed URL pattern returned 404, and Zenplus/eBay/Etsy searches for it returned no matching listings). Sazen Tea's dedicated page (p850) was the only concrete product page found; it is currently out-of-stock with no price shown. All grade/name context beyond Sazen's page comes from aggregated web search summaries rather than a second independently-verified retailer page, so treat the 'Jimyousai, 14th generation' attribution as lower-confidence than the Sazen-sourced facts.
