【日經2貨操作建議】等). * **Core Requirement 3 (Language):** Professional yet understandable financial language. * **Constraint:** Output *only* the summary. 2. **Analyze the Source Material:** * **Topic:** Discussion about reducing the number of seats in the House of Representatives (眾議院議員席次裁減). * **Key Actors:** LDP (自民黨) and Ishin (維新會). * **Status:** Accelerating discussions, aiming for a spring resolution, but major partisan disagreement exists. * **Investor Relevance (Crucial Step):** Political stability and government effectiveness directly impact investor confidence, policy implementation (like economic stimulus or regulatory changes), and thus the Nikkei 225. However, this specific issue (seat reduction) is domestic political maneuvering, not direct monetary policy (like the BOJ) or currency movement (Yen). It signals potential political friction. 3. **Determine Investor Angle & Keyword Integration:** * Since the original content is purely domestic politics (seat reduction), I must *frame* it in terms of political risk/stability, which affects the broader *日本股市投資策略* and *日經225指數走勢*. * *Keywords to integrate:* 日經225指數走勢, 日本股市投資策略, 日經期貨操作建議 (Focus on stability/risk).

(Final decision: Use Draft 2.)雖然市場焦點集中在日本央行利率決策和日圓匯率影響，但投資人也須關注日本國內政局穩定性。自民黨與維新會雖加速討論眾議院席次裁減，但因各黨派分歧巨大，方案難以實現。此政治不確定性可能對短期日經225指數走勢造成波動，建議投資人將政治風險納入日本股市投資策略考量，特別是進行日經期貨操作建議時，應保持謹慎。
