Mr. Naohiko Hatae, Representative Director, e-cloud Inc.
e-cloud NEXT is a fund that allows individuals to invest in growth companies in the middle and late stages. This is the second time we have formed a fund targeting Helical Fusion, and we feel a greater response than last time, with many individual investors choosing to participate in the national theme of nuclear fusion. We want to steadily advance the flow of individual funds and will into the investment area for growth companies, which has traditionally been dominated by institutional investors and VCs. As a company that advocates "a society connected by challenges," we will fully commit to building that mechanism.

Mr. Tadahiko Konoike, Representative Director, Chairman & President Executive Officer, Konoike Transport Co., Ltd.
Fusion energy, through innovative technology, has the potential to significantly change conventional power generation methods and become a new core industry for Japan in the future. For Japan, which relies on other countries for resources such as oil, securing its own energy source is of great significance, and a stable supply of energy unaffected by social conditions and geopolitical risks is an important issue for our company, which supports social infrastructure. Furthermore, in our logistics business, we can expect to reduce environmental impact, such as by utilizing it for electricity in refrigerated and frozen warehouses, which consume more power than ambient temperature warehouses, leading to CO2 reduction. Through our investment in Helical Fusion, we hope to contribute to solving social issues by developing a stable and environmentally friendly energy infrastructure.
Mr. Tadateru Mitani, Representative Director & President, Mitani Sangyo Co., Ltd.
Startups in the nuclear fusion field are emerging one after another. Investors probably compare which nuclear fusion venture is the right one to invest in.
However, for me, Helical Fusion and Mr. Taguchi are beyond such comparisons. The passion of the company and Mr. Taguchi is genuine.
Therefore, instead of comparing which is correct, Mitani Sangyo will continue to collaborate with Helical Fusion to make our choice the correct one.
