Welcome to the Keizai Silicon Valley website. I am pleased to announce that 2015 will be Keizai’s 25th anniversary. Very few people know that Keizai was started by a group of Americans who were working in Japan. They called their group “Kaisha Society”. While Kaisha Society continued on in Japan, one-by-one members began returning to the US, in particular to the San Francisco/Bay Area. It was thus that the “Keizai Society” was formed by former Kaisha Society members who had returned to the area, and that formed the base of the organization that exists today.

Over the past 25 years, Keizai has evolved from an organization focused solely on networking, to a series of bi-monthly forums where we discuss various trending topics in technology, economics, and other areas. Today, Keizai has become an organization of approximately 30 volunteers who work countless hours to provide various events to an audience of close to 5000 Friends of Keizai (newsletter subscribers).

At this 25th year junction, we have reflected deeply on whether the name “Keizai Society” properly describes what we provide to our business community today. We concluded that changing the name to “Keizai Silicon Valley” would more accurately represent that we are based in the innovation capital of the world – Silicon Valley – and that we are considering opening up additional chapters in other cities. Along with the name change, we have also updated our logo to reflect this change.

Our annual theme defines our focus and priorities, and informs our activities, for the coming year. In 2015, our theme — The Power of Innovation to Shape the Future: New Vitality in US-Japan Business — also complements the transformation of Keizai Society into Keizai Silicon Valley. Both Japanese and US businesses will encounter unprecedented opportunities and obstacles in 2015 – domestic and international, economic and geo-political. As Steve Jobs observed, “Innovation distinguishes between a leader and a follower.” Drawing on its deep roots in the global capital of innovation, Keizai Silicon Valley will strive to enhance leadership and vitality in US-Japan business relations and pave the way to a brighter and less volatile future, not just for these two countries, but for the worldwide community of nations.

Looking ahead, I am very excited to continue Keizai’s 25 years of success, and to exceed this record by new leaps and bounds. As one of our recent honorees Nobuyuki Idei says, we look for a quantum leap forward in what Keizai provides to the Valley and the world.

As a recent transplant to Silicon Valley, it was challenging to choose from so many opportunities to meet people and continue to learn. I was fortunate to have multiple people recommend Keizai Silicon Valley’s events as a great way to network with people interested in doing business with Japan or with connections to Japan. Because Silicon Valley is so big, it is easy to feel lost, but at Keizai SV, I felt welcomed by staff and other attendees who seemed genuine in their well wishes and intellectually curious about the topics its programs explored. That’s when I decided to join as a volunteer member. It has been such a pleasure working with other committed volunteer staff to bring quality events to this community. It is this type of group that adds diversity to Silicon Valley, a different perspective that adds to its innovation ecosystem.

I moved back to the Bay Area shortly after graduate school, and I involved myself with Keizai to expand my network and learn more about Japan-US business relations in Silicon Valley. Upon joining the staff, I was welcomed by a highly inspiring, innovative, and positive group of leaders who consistently provide me a new, fresh perspective on the corporate world outside of school and the myriad forms it can take in practice. Volunteering at Keizai has been thrilling and educational every step of the way and I thoroughly enjoy contributing my work to the organization in the realm of social media. I highly recommend it to those who are new to the Bay Area or are seeking to grow their network and expand their approaches to professional life.

Keizai Silicon Valley provides me with an opportunity to view Silicon Valley from the perspective of its role as a global innovation hub–a unique catch-all for the talent and ideas of the world. Through its events and fora, it allows me to stay informed of and connected to the movements of Japanese entities in the Valley, and gives me the network and architecture necessary to help facilitate dialogue and exchange between stakeholders from Japan and the rest of the world represented here.


Keizai Silicon Valley is a Silicon Valley based business and professional networking NPO organization.  Its primary purpose is to provide opportunities for executives and professionals to develop the knowledge and human networks for successful US-Japan business. We provide 1) forums that showcase specialists with expertise on issues critical to the success of entrepreneurs and companies and 2) networking events, such as Shinnenaki (New Year’s Reception), Summer networking, Oktoberfest, and other happy hours, ranging from the largest US-Japan business community event with over 300 people to a casual happy hour event with 30 to 50 people.
