Japan’s Kumamoto City Bolsters Innovative Blockchain Startups
In February this year, the city of Kumamoto in Japan organized the Kumamoto City Pitch 2022–2023, an event designed to bring together startups, established companies, and venture capital firms to promote business growth, according to Japanese tech media ASCII STARTUP.

Promoting innovative startups
With its inception in 2021, the Kumamoto City Pitch has been dedicated to promoting innovative startups with exceptional business models and unique technology. Its objective is to nurture local startups, build communities, and expand business sectors to strengthen the city’s growth.
The event featured presentations from ten companies, including four that had been accepted into the Kumamoto City Acceleration Program “HIGO CANVAS.” The program offers support to projects based in Kumamoto that focus on areas such as cryptocurrency, blockchain, and virtual reality. Among the four accepted companies, two were involved in web3 and blockchain, while the others were working on medication guidance support through user-friendly pillboxes and digital transformation of manufacturing factory management.
Web3-based marketing tool
One of the two blockchain-focused projects was Warashibe, a developer of Web3-based marketing tools. Its main product is a blockchain-powered marketing tool called “BADGE,” designed to enhance marketing efficiency.
BADGE allows users to manage coupons and apps from retail stores in their own wallet. In turn, stores can reduce costs associated with producing and operating coupons and apps. Additionally, stores can analyze spending habits and other data from the wallet to identify target customers for promotions, enhancing the effectiveness of their marketing campaigns.
Warashibe has achieved over 20 successful implementations, some of which involved leading manufacturing companies such as Daihatsu Motor, a major automobile engine manufacturer, and Ricoh, a renowned imaging and electronics company. Beyond coupon management, BADGE offers features like membership cards, credentials, and graduation certificates. The company is also currently developing services to analyze target consumers and manage advertising.
Blockchain biz challenges
IRISA is another startup exploring the blockchain sector. Initially, the company aimed to develop a social media platform incorporating blockchain games. However, the project changed direction due to challenges arising from the limited number of blockchain gamers and the blockchain oracle problem. The latter issue refers to the inherent limitations of blockchains in accessing data outside the network, also known as off-chain data.
