About Japan Climate Alliance (JCA)
JCA was established in 2022 with the aim of building a 'society not threatened by the climate crisis' and to nurture and support professionals with high aspirations and expertise engaged in solving climate change issues. To rapidly transform social systems, JCA's core activity is to build and promote an alliance that 'discovers,' 'supports,' and 'co-creates' people and organizations with strong wills and skills to challenge the status quo.

Background of Appointment: Organizational Development Pro Accelerates 'Status Quo Breakthrough' of the Climate Crisis
Realizing JCA's vision requires 'transformation of the organization itself' and 'co-creation of diverse stakeholders.' On the other hand, Kataryski has been developing organizational support through 'Culture Design' (verbalizing corporate values) and 'Performance Design' (system design) for a wide range of clients from listed companies to governments. In 2024 alone, Mr. Mikami has provided workshops, accompanying support, and seminars to clients in a wide range of industries including transportation equipment, electronic equipment, chemicals, education, trading companies, and government administration. His track record of handling many 100-person workshops and organizational transformations was highly evaluated. Through this appointment, Mr. Mikami will apply his knowledge of new business development, corporate culture integration, and his perspective on 'Serendipity'—turning accidental discoveries into value under uncertain conditions—to JCA's management.

'Having conducted a team-building workshop last year, I am grateful for this connection.

Therefore, while climate change is an unexperienced and unknown field for me, working on this issue as a member of this organization is a new challenge. I want to contribute to meeting those expectations and maximizing results.'
