What is the main reason why Japan’s Prime Minister resigned? As in the title, thank you

Fukuda Yasuo’s resignation and public opinion. From the approval rate of nearly 60% after Abe resigned last year, in less than a year, it has now become about 25%. Such obvious changes clearly indicate that Fukuda's political and economic strategies have failed to achieve popular support. Being in Japan, I can clearly feel that everyone's dissatisfaction with Yasuo Fukuda is getting stronger and stronger. Annuity issues, pension issues, stock price issues, cabinet reform issues, etc. Every time Fukuda goes through a problem, his approval rating drops significantly. The opposition from the opposition parties and the pressure within the Liberal Democratic Party left the Japanese Prime Minister, who had not made many achievements, helpless. As Fukuda said at a press conference yesterday: "Unlike Abe, his resignation is not a health issue, but a political consideration. If there is no new person, there won't be many changes." Whenever I talk about political issues with my Japanese friends, they will reluctantly mention the leadership of the Fukuda cabinet. Every time we give the public something to look forward to, it doesn't take long before it proves to be unfulfillable. The most obvious example is the price of oil. The government planned to cut taxes in order to reduce the burden on ordinary people. Oil prices fell sharply, but within January they rose sharply. Taro Aso had just been brought up with the intention of improving some approval ratings. When many people were looking forward to whether there would be a significant improvement, Fukuda resigned not even a month later. That evening, after the press conference announcing Fukuda's resignation, many media outlets took to the streets to interview people. Among all the interviews, the following sentences were heard most often. I feel that he should finish what he should do. Fukuda's policies are problematic and irresponsible to the people. Indeed, this time through Fukuda's resignation, the opposition parties have raised their voices against the management of the Liberal Democratic Party, and the voices of criticism have become louder and louder. Seemingly harsh. In one year, the Liberal Democratic Party changed its prime minister twice and resigned twice in a flash. The vast majority of the people and opposition parties believed that this was an irresponsible act towards the country and the people. Although Fukuda has many pitiable qualities, he was appointed in a crisis when he was not ready to become prime minister. When dealing with Sino-Japanese relations, he started a new milestone in Sino-Japanese friendship. During the Japanese hepatitis incident, he bowed his head and admitted his mistakes to the people. . . . But everything came to zero because it failed to develop the economy and improve people's lives. My humble opinion Japan is changing now, not developing but stepping or regressing. Today's Japan is no longer a country where all Japanese people came together to work hard for life and prosperity 20 years ago. Although it can be said that Japan has entered a state of economic saturation (they themselves often use this reason to comfort themselves), judging from their work mentality and level of effort, the current generation of Japanese young people no longer have much such awareness. While enjoying the huge fruits of our fathers’ hard work, enjoyment and play take up more of the role. There is a lot worth learning from Japan in the past. But now the Japanese have forgotten what they should learn and what they should do.
