Yasuyuki Tanaka

Yasuyuki Tanaka is a co-founder of ASPASIO Co., Ltd., an independent advisory firm founded in September 2014. ASPASIO’s current corporate profile lists him on the board, and the firm’s July 1, 2026 management announcement names him Chairman & Managing Director.

Tanaka graduated from Kyoto University’s Faculty of Economics and is a certified public accountant. He began his career at the Long-Term Credit Bank of Japan, now SBI Shinsei Bank, and its subsidiaries, where he worked on corporate lending, financial derivatives trading, and business consulting.

In 2001, he founded Brain Link Corporation, where he focused on business reconstruction, financial due diligence, and M&A execution support. In 2007, Brain Link integrated with GCA Savvian Corporation, where Tanaka led transaction-services work including financial due diligence, PMI support, and business reconstruction support. He also served as representative of GCA Savvian’s China local corporation, supporting multiple Japan-China M&A evaluations and executions.

Tanaka is also listed as a Sensing Asia Partner. Sensing Asia describes him as ASPASIO’s representative director and notes his experience in business reconstruction, listing support, cash-flow-management system implementation, financial DD, PMI, and China/ASEAN-related M&A execution.

• I did not find public evidence that Tanaka is currently an active angel investor with a disclosed personal seed-investing mandate, check size, or portfolio.
• ASPASIO’s public positioning is advisory rather than venture-fund investing: the firm says it provides financial advisory, management consulting, and value creation services “from concept to execution.”
• ASPASIO’s focus is middle-market and Asia-oriented corporate growth. A CareerCross company profile describes ASPASIO as a comprehensive M&A advisory firm focused on “Middle & Asia” and states that the firm uses relationships with investment funds and professional firms across Asia to support combinations between Japanese companies and companies in China and ASEAN.
• The firm’s services cover M&A, business succession, capital alliances, cross-border deals, business restructuring, strategy formulation, target identification, negotiation, due diligence, closing, and PMI.
• For companies seeking capital, ASPASIO is more credibly positioned as an advisor around M&A, capital alliances, investment support, valuation, and post-investment value creation than as a direct seed-stage investor.
