Sealed-Lid Shigaraki Ware Coffee Pot 'KOGA' Begins Pre-Sales on Makuake
KISSHIN365, in collaboration with 'Tsubohachi,' a Shigaraki ware kiln established in 1955, has co-developed the 'KOGA' coffee pot. It features a unique sealed design without the typical lid hole, intended to trap the coffee's aroma until the lid is opened. The pot is made from Shigaraki clay from the ancient Lake Biwa layer, which is said to have far-infrared properties. Using a simple full-immersion method—just add hot water and wait 3 minutes—it aims to provide a consistently flavorful brew. Pre-sales began on the crowdfunding platform Makuake on March 24, 2026, with an early-bird price of 8,614 JPY (27% off the planned retail price of 11,800 JPY).

KISSHIN365 (Location: Otsu, Shiga Prefecture; Representative: Okumura), in collaboration with Daiki Okuda, the third-generation head of the Shigaraki ware kiln "Tsubohachi" founded in 1955, began pre-sales of their jointly developed coffee pot, "KOGA," on the crowdfunding service Makuake starting March 24, 2026. By intentionally creating a sealed design that omits the hole typically found on a teapot lid, and by utilizing the far-infrared properties of Shigaraki clay from the approximately 4-million-year-old Ko-Biwako (ancient Lake Biwa) layer, it achieves a coffee experience where the condensed aroma is released the moment the lid is opened. Using a full-immersion method that only requires pouring hot water and waiting 3 minutes, it consistently reproduces a stable taste without any special technique. Against a planned retail price of 11,800 JPY (tax incl.), the Makuake advance purchase price starts from 8,614 JPY (tax incl., 27% OFF).
■ The Background Behind "KOGA"
In recent years, as more people enjoy coffee at home, there's a growing demand for brewing methods that suit individual tastes. Hand-dripping is inconsistent depending on the pour, French presses allow fine particles through, and capsule coffee can lack aroma—existing brewing equipment has always been designed with a trade-off between convenience and quality. To solve this challenge, KISSHIN365, based in Otsu, Shiga, took on the task of fusing the traditional techniques of Shigaraki ware with coffee culture.
■ Product Overview: Coffee Pot "KOGA"
〈The Product's 5 Commitments〉
【1】Sealed Design with No Lid Hole—Traps Aroma, Releasing it Gently Upon Opening
Typical teapots have a "lid hole" to let steam escape. However, this also allows the coffee's aromatic compounds to escape. KOGA intentionally omits this hole and glazes the underside of the lid, creating a design that circulates the steam internally. The experience of the trapped aroma gently rising the moment you open the lid is something not found in existing coffee brewers.
【2】Richness and Flavor from 4-Million-Year-Old Clay—Shigaraki Clay from the Ko-Biwako Layer
The body of KOGA uses Shigaraki clay from the approximately 4-million-year-old Ko-Biwako layer. Making the most of the unique texture of Shigaraki ware, it is finished as a vessel to enrich your daily coffee time.
