IKUMI

Palate. IBUKI describes IKUMI as a 'Crisp Sencha' offering a sense of tranquility and refreshing clarity, evoking 'lunar serenity and coolness'. In a June 2025 post, it described IKUMI as a higher-grade sencha with a balanced taste.^[1],[5],[6]

Yabukita Sencha -- Tea Base. The IKUMI product specification lists sencha of the Yabukita variety from Ikumi, Shimada City, Shizuoka Prefecture, harvested between April and May 2026. The tea is made from the first harvest of the Yabukita variety. Another statement on IBUKI's website gives the harvest as April–May 2025.^[3],[5]

Water -- Extraction Medium. IBUKI describes the water for its bottled teas as drawn from the Oi River, a Southern Alps river naturally filtered through geological strata, and further softened at its factory into 'super soft water'.^{[1],[2],[3],[4]}

Ingredients Policy. IBUKI states that its bottled teas are made without additives, using only water and tea leaves.

IKUMI is a sencha bottled tea named after the Ikumi area of Shimada City, Shizuoka Prefecture, where its tea is produced. Ikumi is one of the legacy areas in the history of Japanese tea production where sencha has been handed down.^[1]

IBUKI blends and fire-roasts the Yabukita tea leaves for IKUMI in-house to bring out the variety's characteristic flavour. According to IBUKI, a special extraction method draws out the umami, sweetness and richness of the Yabukita tea to the maximum. IBUKI also states that IKUMI delivers a distinctly different taste from teas brewed in a kyusu, the Japanese teapot.^[2],[3],[4]

Temperature. IBUKI recommends serving its bottled teas cold, warmed slightly in the hand to release aroma. Its bottled teas are delivered by refrigerated service and require refrigeration.
