Prime Minister Shigeru Ishiba's comment that a "grand coalition is also an option" reflects the current realities of Japanese politics. Given the dominant position of the LDP, it’s unlikely that many opposition lawmakers would refuse an invitation to join. A grand coalition could very well serve as a stepping stone toward reinforcing a system dominated by the LDP.
However, the Prime Minister's acknowledgment of the risks of resembling a "one-party state" like the Taisei Yokusankai era is noteworthy. To preserve Japan's democracy, it is crucial to ensure that diverse opinions remain respected and represented. If PM Ishiba decides to pursue this path, he must clearly explain the rationale and goals behind it, ensuring transparency and accountability to the public.
