■ Inaugural Comments
'I am Yoshifumi Sakamoto, and I have assumed the position of CTO at SpaceBlast. SpaceBlast is a company that challenges itself to create next-generation social infrastructure by combining space technology development and digital technology, under the slogan "Launching the Future from Space."
I have been consistently involved in the front lines of research and development of advanced technologies, business implementation, and industrial application. From now on, as the CTO of SpaceBlast and DigitalBlast, I will oversee the technology strategy and strongly promote the realization of next-generation social infrastructure starting from space, including orbital data centers, by bringing together expertise in space development, AI, and digital technology.
The space industry is now transitioning from the demonstration stage to the social implementation and industrialization stage. What is required in this transition is not just dreaming big, but the power to transform technology into real value. I consider it my mission to further strengthen the technological assets and business foundation of SpaceBlast and deliver new value that connects space and the ground to society.
I will work with all my might to make space a more familiar social infrastructure through the power of technology and to lead SpaceBlast to its next stage of growth.'
