Mitsui & Co. has traditionally pursued solutions to social issues through business, while flexibly adapting its business models in response to changing environments. Given today's stronger emphasis on sustainability as a requirement of corporate management, this is the perfect time to embody the full potential of Mitsui & Co.'s long-cherished management philosophy and commitment to value creation. We uphold "Creating Sustainable Futures" as the theme for Medium-term Management Plan 2026, which we announced in May 2023. In line with this theme, we will fully incorporate sustainability perspectives and offer our cross-industrial solutions, what we call real solutions , to social issues faced by a wide range of industries that are intricately interlinked to one another, and thereby pursue the materialization of our aspiration as set forth in Mitsui's corporate mission -"Build brighter futures, everywhere".
