Group integration synergies
- Post-office network × finance: Using the nationwide ~24,000 局 as sales counters for yucho / kampo-life. Counter fees (financial 2 社 → Japan Post) are the main axis of intra-group transfer
- Logistics × EC: Coordination between Japan Post’s last-one-mile network and EC platforms. The former Rakuten G alliance was positioned in this context
Alliance / acquisition strategy
- Rakuten Group capital and business alliance (2021-03-12): Japan Post Holdings subscribed to a third-party allotment of new shares of Rakuten Group (4755), investing approx. 1,500 億円 (investment ratio 8.32%, the 4 位 shareholder). Coordination in logistics, mobile, finance, and EC. Subsequently, following the decline in Rakuten G’s share price due to the underperformance of the Rakuten Mobile business, Japan Post Holdings recorded an extraordinary loss (impairment) of approx. 800-850 億円 in the 2023 年 4-6 period
- Phased disposal of financial 2 社 shares: Under the Privatization Act, Japan Post Holdings targets a phased disposal of yucho / kampo-life shares. On the other hand, due to the inseparability of the post-office network and financial sales, there is political resistance to complete separation
- Additional secondary offerings of government-held shares: Secondary offerings of government-held shares have been carried out successively as reconstruction funding / national-bond redemption funding
Overseas strategy
- The former Toll Holdings (a major Australian logistics player, acquired 2015-05 ~6,200 億円) → **sold 2021-04 ** (after recording a large goodwill impairment). Overseas logistics M&A is effectively in withdrawal mode
- yucho / kampo-life expand global exposure on the investment side through overseas bonds and alternatives
4. Regulation / policy
- Supervision: MIC (postal administration / universal service) + FSA (yucho banking business / kampo-life insurance business)
- Governing laws: Postal Privatization Act / Japan Post Holdings Co., Ltd. Act / Japan Post Co., Ltd. Act / the respective governing laws of Japan Post Bank Co., Ltd. and Japan Post Insurance Co., Ltd.
- Government-holding obligation: The Minister of Finance holds more than 1/3 of Japan Post Holdings shares for the time being
- Disposal target for the financial 2 社: Japan Post Holdings disposes of yucho / kampo-life shares in phases (timing and ratio operated by cabinet order / cabinet decision)
- Universal-service obligation: Japan Post bears the obligation to provide nationwide flat-rate postal service
- Recent policy issues:
- 2019-2020 kampo-life improper-sales incident → governance / sales-structure reform
- 2024 ~ postal-rate increases (25 g 84 円 → 110 円, etc.) and the postal business turning loss-making
- 2025 ~ digital post / electronic mailbox / MyPost concepts
