○ Amid the transition into a super-aged society and the growing income gap between the statutory retirement age (60) and the national pension eligibility age, domestic debates on extending the retirement age have resumed; however, finding concrete solutions remains challenging due to interlocking issues with wage structures and youth employment.

• Accordingly, this report aims to derive strategic implications for senior workforce utilization and productivity retention by analyzing policies and corporate case studies from Japan and Germany—manufacturing-based nations that implemented retirement extensions and continuous employment ahead of South Korea.

○ [Japan's Policies and Corporate Cases] Japan adopted a phased, selective framework that gradually strengthened the statutory retirement age from an "effort obligation" to a "legal obligation." Major corporations pursue the effective utilization of senior talent through wage system restructuring (Nippon Steel) and role redefinition (Toyota).

• Policy: Companies are permitted to choose among extending the retirement age, abolishing the retirement age, or introducing continuous employment (99.9% of companies secure employment up to age 65, 65.1% of which adopt continuous employment). The recent debate has shifted toward "what wages and roles should be assigned to enable senior workers to contribute meaningfully to organizational performance."

• Nippon Steel: Managed labor cost burdens associated with raising the retirement age to 65 by combining age-based pay reductions with the expansion of job-based pay, alongside institutional adjustments such as tenure caps on leadership roles and geographical work-location limits.

• Toyota: Redefined senior personnel from auxiliary support to core frontline staff, simultaneously securing motivation and productivity through the introduction of the SP-A grade (65–80% of peak wages), a pivot to performance-based systems, and the "Health Vision" initiative.

○ [Germany's Policies and Corporate Cases] Instead of a mandatory retirement age, Germany uses the statutory pension eligibility age (67) as a benchmark to encourage "flexible, elective long-term tenure." Major corporations redefine senior workers as knowledge & capability assets and institutionalizing know-how transfer.

• Policy: Provides diverse retirement pathways—such as phased partial retirement (Altersteilzeit), lifetime working time accounts, and flexible pension systems (Flexirente)—with practical implementation detailed through industry-level collective agreements and company-level labor-management accords.

• Thyssenkrupp: Implemented a relay model linking phased senior retirement with youth hiring, successfully transferring tacit knowledge across steel manufacturing sites via designated knowledge transfer officers and a "Senior Expert Pool."

• BMW: Differentiated senior workforce utilization and recruitment strategies by job family—focusing on automation and role reassignment for manufacturing operations, while actively securing new talent in engineering and administrative functions.

○ While target timelines and strategies differ, both nations approach retirement age extension as an initiative to "continue employment while redesigning conditions," advancing policies that enhance intergenerational continuity.

• Korean enterprises must establish wage structure reform as a prerequisite condition, bridging the experience and tacit knowledge of senior workers to junior talent mentorship and skill transfer, thereby designing senior employment and youth growth as mutually reinforcing dynamics.
