To state the conclusion first: it can be stated with absolute certainty that Japan is determined to go to war with China. Even without the Taiwan issue, it still wants to fight China. The reasons are as follows:

I. The Chinese economic giant is devouring Japan, and before it is completely reduced to a second-tier nation, the situation forces it to take desperate measures and launch war.

China has achieved breakthroughs in multiple core industries where Japan once led, such as new energy vehicles, photovoltaics, and liquid crystal panels. Through large-scale development and technological iteration, it continues to squeeze Japan's global market space for these industries. The following provides detailed explanations with specific examples and data:

1. New Energy Vehicles Industry: Japan was once a benchmark in the global automotive industry, but China achieved a leapfrog development by adopting a new energy route. In 2023, China's automotive export volume reached 3.27 million units, and in 2024, it approached 6 million units, ranking first globally. In contrast, Japan's bet on hydrogen energy has encountered obstacles due to lagging infrastructure. In 2022, Japan's electric vehicle sales reached only 548,000 units, accounting for just 9.1% of the global market share. Among the top 20 best-selling new energy vehicles in China in 2022, there was not a single Japanese model. As Toyota and other automakers later adjusted their electrification strategies, their market share had already shrunk significantly.

2. Photovoltaic Industry: In the last century, Japanese companies like Kyocera and Panasonic dominated the photovoltaic markets in Europe and America. Currently, China accounts for 70% of global photovoltaic production capacity. Due to high costs and slow transformation, Japanese photovoltaic companies have gradually withdrawn from the mainstream market, with their former monopoly position completely replaced by Chinese companies.

3. LCD Panel Industry: In the early 1990s, Japanese companies Sharp and Toshiba held a far greater number of LCD panel patents than other countries, with a global market share close to 90%. Japan's global LCD panel market share has continuously shrunk to less than 20%, with most Japanese companies gradually exiting panel assembly production, retaining only some core material-related businesses.

4. Semiconductor Industry: In the 1980s, Japanese companies like Toshiba and NEC held over 50% of the global semiconductor market share. Today, the competitiveness of Japan's semiconductor finished products has declined, with its share dropping below 20%. More critically, Japan's semiconductor industry is highly dependent on the Chinese market and raw materials.

5. Consumer and Export-Reliant Sectors: In the first half of 2025, Japan's auto exports to China accounted for nearly 37% of China's total imports during the same period. This high level of dependence means that changes in demand from the Chinese market and industrial adjustments will directly impact the development pace of related industries in Japan, further highlighting the constraints China's economic structure imposes on Japan.

Of course, this kind of "devouring" is the result of generations of Chinese people's relentless self-improvement, independence, and hard work to overcome challenges, the result of technological and scale dominance, and the outcome of genuine free competition in the global market economy, where it's a battle of wits and strength.

But Japan is not willing to accept this. The mentality of envy and resentment is inevitable. How to break through? Taking advantage of the time when China is strong but not yet fully strong, using war to disrupt China's development plan is the best choice.

II. Japan has never feared China and has never been severely defeated by China; at most, it would just retreat to its home islands to continue its development.

The opportunity cost of war is far greater than the war cost. Therefore, from top to bottom in Japan, there is a strong sense of superiority over China and a mindset of taking China as a target. As a result, the Japanese people are fundamentally not afraid of going to war with China. On the other hand, when it comes to the U.S. — the incineration by Li Mei, the nuclear bomb of the fat little boy — it leaves Japan with endless 回味; when dealing with Russia — the mere mention of "Siberia" makes the little Japanese tremble…

III. After Taiwan's return, from the perspective of Japan and relevant public opinion analysis, it will have some impact on it.

The impact of Taiwan's return on Japan's economy is concentrated in core areas such as energy transportation, industrial chains, and tourism. The following are the specific contents:

1. Energy and maritime shipping costs have skyrocketed. 90% of Japan's oil and 99% of its liquefied natural gas rely on transportation through the Taiwan Strait, and 40% of its international trade cargo volume also passes through this channel. According to calculations by Japan's Ministry of Economy, Trade and Industry, if the strait's transportation is disrupted for 1 month, Japan's GDP will suffer a loss of 1.2%; if it needs to reroute east of the Philippines, the voyage will increase by 15 days, transportation costs will rise by 60%, and a prolonged disruption of 3 months could paralyze its key industries such as automobiles and electronics.

2. Disruption to high-end manufacturing supply chains. Taiwan is the core region for the global semiconductor industry. After Taiwan's return, Japan will find it difficult to rely on its existing Taiwan-related industries to ensure supply chain stability, potentially facing fluctuations in semiconductor supply, which could in turn drag down its manufacturing production and profits.

3. Regional economic influence marginalized. Japanese public opinion believes that Taiwan's return will reshape the power dynamics in East Asia, and China may leverage Taiwan to integrate the East Asian economic bloc. Japan's investment attractiveness in ASEAN will decline, and its role in the Indo-Pacific strategy will also be marginalized, further weakening Japan's regional economic influence.

IV. Due to historical reasons, Japan has always regarded Taiwan as territory it "lost" due to its defeat in war.

Japanese right-wing groups and right-wing media like the Nikkei Economic Review are influenced by the historical impact of 50 years of colonial rule, harboring a strong "Taiwan complex." They hype the wording in the "Treaty of San Francisco" that "Japan relinquished its rights to Taiwan without mentioning its return to China," creating the narrative of "Taiwan's status being undecided." Some right-wing elements also carry a "sense of unfinished business," viewing Taiwan as a symbol of "lost territory," and even right-wing politicians like Abe Shinzo and Takahashi Sanae frequently 抛出 "If Taiwan is in trouble, Japan is in trouble" rhetoric, which also implies Japan's geopolitical ambitions and colonial leftover mentality toward Taiwan.

V. Japan's domestic contradictions are accumulating, needing a way to unite the forces - war

Japan's domestic contradictions have become very prominent. Whether it's between the government and the people or within the government itself, the contradictions are very obvious and difficult to reconcile. The constant change of Japanese prime ministers, with nine changes in ten years, is a significant manifestation of high-level political division. The popularity of otaku, NEET, and waste culture is the silent resistance of Japan's younger generation's frustration and suppression! Seniors still working in supermarkets is also an 体现 of Japan's lack of social vitality. For these contradictions, Japan has changed many prime ministers, but still no solution... The contradictions continue to accumulate and will eventually explode... In this situation, diverting the trouble to other countries is a tradition of Japan.

VI. The United States and Europe need to let the vicious dog Japan take the stage to consume China...

The US doesn't want to engage in a direct hot war with China, but it also cannot allow China to develop smoothly. Proxy wars are its best option...Taiwan, the Philippines, India, the US has experimented with all of them~ they are all too weak...Japan's strength is enough to be a qualified dog!

How to break the war against Japan? Three sentences: 1. Must fight fiercely, make it hurt; 2. Cut off the mess quickly, cannot turn it into a stalemate war, like the big bear, being continuously exhausted; 3. Hit Japan to deter the US.

Using nuclear bombs directly is the best choice.
