Unlike chagama (large iron kettles used over sunken hearths in matcha ceremony), tetsubin are designed for sencha — smaller, more portable, and often featuring decorative spouts for direct pouring.\u003cbr\u003e\u003cbr\u003eThe koshikiguchi style takes its name from the koshiki, a traditional Japanese steamer with an upright rim. This raised, standing mouth gives the kettle a distinctive profile and practical advantage: easier pouring control and reduced splashing. Hashimoto Tatsutoshi's work is rooted in traditional casting techniques, where molten iron is poured into sand molds to create textured, organic surfaces.\u003cbr\u003e\u003cbr\u003e*\"Iron holds heat, time builds patina — each pour a quiet ritual repeated.\"*\u003cbr\u003e\u003cbr\u003e━━━━━━━━━━━━━━━━━━━━\u003cbr\u003e\u003cbr\u003e🔹 [ DEEP-DIVE COMMENTARY ]\u003cbr\u003e\u003cbr\u003e**Tetsubin Heritage**: Cast iron tetsubin emerged during the Edo period as tea culture expanded into the more relaxed sencha tradition. Sencha, introduced from China, emphasized personal taste and connoisseurship over codified ceremony. Tetsubin became tools of individual expression — each kettle's patina developing uniquely over years of use.\u003cbr\u003e\u003cbr\u003e**Koshikiguchi Design**: The raised mouth prevents drips and allows precise control, while the upright silhouette creates visual balance with the arched handle. This is design through use — every curve refined by generations of tea makers seeking the perfect pour.\u003cbr\u003e\u003cbr\u003e**Material Contrast**: The copper lid introduces a subtle material contrast. Copper conducts heat differently than iron, preventing the lid from becoming dangerously hot while adding a warm visual accent. The ball-shaped knob offers both grip and decorative presence.\u003cbr\u003e\u003cbr\u003e**Patina \u0026amp; Water Quality**: The 1.7 kg weight indicates substantial casting — thick walls that retain heat and resist cracking. Over time, the interior develops a mineral coating (yu-aka, 湯垢) that protects against rust and further softens water. This patina is prized as a record of every tea session held.\u003cbr\u003e\u003cbr\u003e**The Act of Pouring**: In sencha ceremony, the act of pouring from a tetsubin is deliberate and meditative. The kettle's weight, the arc of the handle, the sound of water leaving the spout — all become part of the experience.\u003cbr\u003e\u003cbr\u003e━━━━━━━━━━━━━━━━━━━━\u003cbr\u003e\u003cbr\u003e🔹 [ 日本語解説 ]\u003cbr\u003e\u003cbr\u003e【基本情報】\u003cbr\u003e• 作家：橋本辰敏\u003cbr\u003e• 形状：鉄瓶 立口・甑口\u003cbr\u003e• 素材：鋳鉄（本体）、銅（蓋）\u003cbr\u003e• 寸法：高さ約21cm × 横幅約17cm\u003cbr\u003e• 重量：約1.7kg\u003cbr\u003e• 付属：桐箱（青紐）\u003cbr\u003e• 状態：良好（割れ・欠けなし）\u003cbr\u003e\u003cbr\u003e【解説】\u003cbr\u003e橋本辰敏による甑口・立口形式の鉄瓶です。鉄瓶は江戸時代に煎茶文化の広がりとともに発展した茶道具で、湯を沸かすだけでなく、水をまろやかにし、微かな鉄分を茶に与える役割を果たします。\u003cbr\u003e\u003cbr\u003e甑口とは、古来の蒸し器「甑」の立ち上がった口縁に由来する形式で、湯切れが良く注ぎやすい設計です。丸みを帯びた堂々とした鋳肌は、砂型鋳造による細かな粒状テクスチャが施され、鉄瓶特有の趣を醸し出しています。\u003cbr\u003e\u003cbr\u003e銅蓋には装飾的な玉摘みが付き、鉄の本体との素材の対比が美しい。重量1.7kgの堅牢な作りは長年の使用に耐え、内部には湯垢が育ちさらに水質を向上させます。深い黒褐色の肌は、煎茶席における静かな存在感を放ちます。\u003cbr\u003e\u003cbr\u003e━━━━━━━━━━━━━━━━━━━━\u003cbr\u003e\u003cbr\u003e🔹 [ SHIPPING \u0026amp; PACKAGING ]\u003cbr\u003e• Dispatch: Within 1-6 business days\u003cbr\u003e• Carrier: Japan Post EMS \/ UPS (with tracking)\u003cbr\u003e• Packaging: Carefully wrapped with protective materials\u003cbr\u003e\u003cbr\u003e*Water remembers the iron that warmed it — and carries that memory to the cup.*","brand":"The Modern Zen Archive","offers":[{"title":"Default Title","offer_id":61577434661234,"sku":"241123-a-0752","price":1571.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/5680\/3698\/files\/241123-a-0752_1.jpg?v=1770624644","url":"https:\/\/checkout.themodernzenarchive.com\/products\/cast-iron-tetsubin-by-hashimoto-tatsutoshi-koshikiguchi-sencha-kettle","provider":"The Modern Zen Archive","version":"1.0","type":"link"}
