Japan Cryptocoin Association Launches QR’z, QR Code Picture Logic Puzzle System

-Making QR Codes More Familiar and More Fun-

The Japan Cryptocoin Association (Headquarters: Osaka, Osaka; Representative Director: Kenichi Yamashita) is excited to announce the launch of QR’z ( on February 28th, 2019 with the objective of raising awareness of the convenience and practicability of QR codes, which are adopted in a cashless society, as a “new form of advertisement.”

QR’z Is a New Puzzle System Combining Advertising and PR

As transiting into a cashless society, opportunities that make QR codes familiar are important regardless of age. Under these circumstances, the Japan Cryptocoin Association launched “QR’z” with the belief that a fun and creative way learning about QR will lead to the creation of new values.

QR’z is free to play. It is capable of transforming sharable information from companies and organizations into QR codes. It can also change the logo embedded within the OR code into desired logos.

An Evolved Form of Picture Logic

Up until now, it was possible to determine the pattern before completing a picture logic puzzle. However, user cannot determine the regularity of the patterns in QR’z at first glance, meaning that user do not know if their solution is correct or not until completing the last grid. In addition, as soon as user completed the puzzle, they will be able to read the information contained in the QR code. If the QR code is a “secret key for cryptocurrency” or “gift codes for various companies,” user will receive additional enjoyment immediately after completion, in addition to the joy of solving the puzzle. “Presents of words” should also bring joy. In these manners, the utilization of QR’z can be applied to various fields, and in multiple ways of usage.


Future Development

The Japan Cryptocoin Association aim to build out an environment in which individuals, companies, and organizations can create puzzles themselves. This will allow them to share information for publicity when needed. Symbols that hide QR codes can also be set up individually. Since users accumulate points as they solve puzzles, their rankings can be displayed. Puzzles can be restricted to certain countries, such as puzzles that are limited to people in Cambodia, and it is also possible to look at a map and see how many people from each country are solving the puzzle that you created.

Encountered bitcoin in 2012. Established Japan Cryptocoin Association in 2014 after being fascinated by the possibilities of blockchain technology. Vigorously working to popularize safe use of cryptocurrency, as well as secure settlements and serves as a lecturer for the cryptocurrency skill test hosted by the association.

“I believe that in Japan, cryptocurrency tends to be seen as the subject of speculation, as only a select number of people who have experience being involved with cryptocurrency focus on its applications in finance and potential as a technology.

Under these circumstances, cryptocurrency has enormous latent potential in fund-raising and charity. Because cryptocurrency is based on a decentralized system, it allows the value of money to be transferred directly from an individual to another individual without going through a centralized institution. QR codes create an environment where anybody can do so easily. In addition, settlements and remittances that QR codes are gradually gaining attention in China and Japan. Bitcoin was the first system that gave birth to this culture.

As a result, our association came to with to be able to provide opportunities to take a close look at the true qualities of cryptocurrency while enjoying QR’z and becoming familiar with QR codes. In a cashless society that is expected to grow using QR codes, we would be delighted if more people become familiar with the concepts of “cashless” and “cryptocurrency.””
