株式会社自然と未来 星子文

Aya Hoshiko is the Chief Executive Officer of Nature and Future. The idea for a biodiesel venture came to her while working for a shipping company. Five years ago, she established her biodiesel refinement and sales enterprise. With the phrase “don’t give up” as her mantra, she is putting all of her effort into the realisation of her dream. She gathered the support of various people in Kumamoto by “rolling up power into a weapon,” and won a government cabinet minister’s environmental award in December 2013. She continues to face challenges without fear of failure, and carries herself in such a way that gets her called the Second Kumamon.
