Izumibashi Shuzo, a brewery to thoroughly perform Sake brewing process, from rice cultivation to brewing, installed a traceability service



 SBI Traceability co., Ltd (HQ: Minato-ku, Tokyo, Representative director: Tomohito Wajima) announces that SHIMENAWA, a traceability service to protect brands through blockchain technologies, was installed at Izumibashi Shuzo Co., Ltd. (HQ: Ebina City, Kanagawa Prefecture, Representative: Yuichi Hashiba). Izumibashi Shuzo thoroughly performs Sake production from rice cultivation to brewing, as a ‘cultivation & brewing brewery’ in Ebina City and its neighboring district.

  Launched in 2003, Izumibashi Shuzo’s dragonfly-marked label “Tonbo Label” celebrates its 20th anniversary this year and is gradually recognised across the world. This time, 6th generation master’s dream (of introducing as high polishing ratio as 20%) came true under a strong determination. ‘The Sake is unprecedented and considered very special. This is why we chose to adopt SHIMENAWA technologies’, the master says.



  Through a digital pairing technology of blockchain and NFC tags, SHIMENAWA protects product brands by providing an authenticity certificate, destination tracking (useful for a prevention of fake products) and bottle opening signals. Authenticity certificate and traceability functions will ensure producer’s responsibility to deliver authentic products, which could help to seize a higher level of trust from consumers.

  In addition, bottle opening signals allow consumers to recognize the opening of the products by themselves to feel more secured about conditions of the products.

  This function is also useful to obtain information of when and where the product was opened (consumed) as breweries can utilize this information to strategically administrate its business.

  Blockchain aims to track the values by sharing the history of data modification on the network using the modification detecting system.



*1  Blockchain is a technology enabling a preservation of values by sharing data modification history on the network. Electronic signature and hash pointer are used for their tamper-resistant data structures. The technology is useful to build trustable end-to-end traceability system by sharing certificates for authenticity and quality of physical assets.


*2 NFC (Near field communication) tag technology is a high frequency NFC band technology that enables to provide unique IDs to physical assets, and strongly associate these IDs with important information stored in blockchain. The technology is used for credit cards and My Number Cards (Japanese social security cards)

Brief introduction:

  Izumibashi Shuzo was founded to start the Sake brewing in 1857 of the Edo Period, at Ebinagochi (海老名耕地), taking advantage of its natural resources such as abundant rice and the water source from the Tanzawa Mountains.
