About
Takuya Iwasaki and Rokugeisha
I’m Takuya Iwasaki, founder and representative of Rokugeisha. My work focuses on analyzing and visualizing data, particularly survey data used to inform policymaking, and developing business intelligence (BI) tools to help people use it.
I founded Rokugeisha in Sapporo in 2001. Our initial work was mainly planning and producing student recruitment communications for private universities. Through our work with universities, our activities expanded into research communications, communications for research institutions, research support and science communication. When I took up a research support role at Osaka University, I put the company’s activities on hold. With guidance from many people, I continued to gain experience in research support and science and technology policy. I have now resumed Rokugeisha’s activities.
I’m interested in the relationship between learning and work, and in how people develop knowledge and expertise. Where and what have people studied? What work do they do, and what knowledge do they use in it? I enjoy exploring the variety of paths people take and the unexpected connections that emerge in the data. I also want to think about what lies behind their choices and actions.
On this site, I publish data, analyses and visualization tools as materials for thinking about your own learning and work, and how you develop knowledge and expertise. I hope they give people a starting point for sharing questions and discussing them, and that new ideas emerge from those conversations.
