I also think that most of us get wisdom from a wide range of sources, from the people we know and love, from strangers on the street, from therapists and counselors, from teachers, from books, from podcasts, so I turn in all of those directions.

Many times when I found myself at a personal crossroads – when I graduated from Hitotsubashi University and was unsure about whether I wanted to go into research or become a businessman, when I quit my job at the Industrial Bank of Japan (currently Mizuho Bank), when I founded Rakuten, when I tried to buy Tokyo Broadcasting System (TBS) – I always visited my dad in Kobe to ask his advice.

Yes, I’m part of the Rolex mentoring programme for the 2023-2024 season, and my mentor, the architect Anne Lacaton, is actually the one who suggested I should do a project here. I explained in my application about how much influence it’s had on me, so she told me we should take advantage of this time together and work on something in my hometown. Her guidance has been so crucial, especially because I have such strong personal ties to the area, she’s been extremely helpful in reminding me of what my role is as an architect.

People refer to the ‘LMB culture’ as the thing, one of the things, that makes it special. It’s an attention to people who are willing to tackle very big problems. I mean problems that are so big that you couldn’t just solve it in a grant. The kind of problem that you could devote your life to. I was very fortunate in having mentors of Fred Sanger and César Milstein who exercised a kind of very benign mentorship but encouraged us to think big.
