Even though it’s been more than a year since Hyperledger was born, there hasn’t been much of an opportunity for Japanese enthusiasts to learn about the initiative.

Hyperledger Executive Director, Brian Behlendorf came over to Japan last year to talk about the project and encourage people to work together in the community, but there aren’t many other Japanese resources to turn to. That was a big reason why we kicked off the Hyperledger Tokyo Meetup and the first meeting was a huge success! So much so, that it completely sold out! We booked a venue with a max capacity of 180 people, and all 180 seats were sold out a week prior to the event. We accepted at least 10+ people afterwards and added extra chairs in the conference hall to accommodate attendees. Interest was high to say the least!

We had several Hyperledger member speakers and all of which did an amazing job. It was a rich and fruitful five hours for attendees to learn about all things Hyperledger.

Toshiya Cho of Hitachi and Hyperledger Board Member, kicked off the event by providing a brief overview of Hyperledger. Nishio Yamada and Satoshi Oshima of Hitachi, explained the technical overview of Hyperledger Fabric. Satoshi took the stage wearing his “I am Satoshi” t-shirt (one of very few people in the industry that can actually pull that off.)

Then, Akimitsu Shiseki, took an opportunity to explain one of our latest developing projects, Fabric Composer, which aims to lower the bar in working with Hyperledger for non-platform developers. Makoto Takemiya of Soramitsu and the founder of Iroha then talked about Hyperledger Iroha, another framework in incubation. Iroha is a great framework for small to medium sized use cases.

Yuta Namiki of NEC delivered an extremely interesting talk, as a database expert, where he analyzed the differences between traditional relational databases and blockchains (distributed ledger tech).

Takahiro Inaba and Shinichi Yamashita of NTT DATA, talked about things to consider when implementing a blockchain system; starting from how to select blockchain products, the differences between cloud vs. on-premise, which solution is cheaper to issues like who should own the node and so on.

Finally, Naruto Takiguchi of Fujitsu, talked about his experience and learning from a real POC with a Japanese financial institution. He explained the issues he faced during the POC, and for each issue, he explained the difficulty he faced, how he actually solved it, and what needs to be contributed to the community as a result of the lesson he learned.

Overall, it was a great experience and attendees were able to learn about Hyperledger from a wide variety of perspectives. This was a perfect introduction for the Japanese community, and we’re looking forward to more events in the future. We’re already in the midst of planning the next meetup, which will be much more technical focused.

Big thanks to Fujitsu for letting us use such an wonderful event venue and to all the other members participation in this great event! Anyone interested, can join the Hyperledger Tokyo Meetup here: https://www.meetup.com/HyperLedger-Tokyo/
