On March 9, 2026, a talk event was held at TSUTAYA Bookstore MARUNOUCHI in Marunouchi, Tokyo, featuring Takaya Taguchi, CEO of Helical Fusion, and Kei Tanaka, a former Goldman Sachs employee and investor. The event was held to commemorate the decision to reprint Taguchi's book, "That's Why We Create the Sun," which was published in January 2026, and to express gratitude to everyone who supported its publication.
The event, titled "Why Nuclear Fusion Now? ~Entrepreneur Takaya Taguchi and Investor Kei Tanaka Discuss the Essence of the 'Last Energy Revolution'~," received far more applications than anticipated for the venue's capacity, and we had to hastily hold a lottery for attendees. Thank you to everyone who took the time out of their busy schedules to attend. We also apologize to those who were interested but unfortunately could not be accommodated this time.
Many participants in this event were learning about fusion energy for the first time. Taguchi reiterated the basics of nuclear fusion and shared the current status and future prospects of Helical Fusion's efforts to implement fusion energy in society.
Furthermore, there were many real-world stories that only these two, who are on the front lines and taking on challenges every day, could tell. Ms. Tanaka spoke about why she supports big challenges such as deep tech startups, and how she came to choose Helical Fusion as one of them. At one point in the audience, she asked about the secret to maintaining health and high motivation despite her busy schedule.
And guess what! We've decided to make a recording of this event available on the Helical Fusion YouTube channel at a later date. We hope that those of you who couldn't attend this time, and those of you who would like to review the content again, will find it useful. We will let you know as soon as it's ready, so please look forward to it.
