Can Japan and India’s AI alliance challenge China and U.S. dominance?

AI innovation is dominated by the U.S. and China. It’s a polarizing contest which has Japan partnering with India to develop “trustworthy AI.”

Japan and India have solidified an AI-centered partnership after holding a series of technology events and government-led discussions spanning AI governance, semiconductor supply chains, data centers and domestic language AI models.    

In late April, the two countries held their first strategic dialogue alongside an AI-startup event in Mumbai and Bengaluru. The event culminated in Japanese AI startup ONESTRUCTION and India’s DataKaveri Systems signing a memorandum of understanding (MOU) to expand AI collaboration.

ONESTRUCTION said the agreement allows for the technical exchange of urban and construction data as well as AI applications.

According to the company, construction-related data is the least digitized and most fragmented form of global data. They plan to jointly develop AI use cases for smart cities and urban infrastructure.

“Japan has very strong domain knowledge in manufacturing and construction. But it struggles to scale with agility and speed. India excels at all of that,” said CEO Lucas Haywood on February 16.

What is driving the Japan-India AI alliance?

Japan is racing to incorporate AI into its economic security agenda as the technology becomes an economic battleground.

In November 2025, Prime Minister Sanae Takaichi unveiled a new economic strategy headquarters focusing on AI, semiconductors, aerospace, and defense. It’s aimed at revitalizing the country’s industrial base with government investment.

At the same time, India is emerging as an AI innovation hub and talent powerhouse. It ranks third globally in AI vibrancy behind the U.S. and China, according to the 2025 Stanford AI Index Report.

At India’s AI Impact Summit in February, Japanese and Indian industry leaders praised the partnership as being deeply complementary.

“If India with its skill set, innovation and large market combines that with the diligence, governance, trust and reliability of Japan, we can serve not only our own countries but the entire Global South,” said Sunil Gupta, CEO of Yotta, an Indian data and cloud service provider.

Japan and India’s AI partnership began with the Japan-India AI Cooperative Initiative and the subsequent India and Japan Digital Partnership 2.0 MOU in August 2025.

The MOU serves as the blueprint for integrating Japan’s industrial and hardware strengths with India’s software, talent and digital infrastructure ecosystem.

The partnership could help scale Indian AI adoption across the 1,400 Japanese companies that operate in India.

Sovereign AI ecosystems

Japan is looking to ‘sovereign AI’ as a geopolitical alternative aimed at ensuring data sovereignty, security and independent control of software, computing and networks.

The U.S. hosts the world’s leading AI research, chip stack and cloud companies, namely, OpenAI, Anthropic, Meta AI, Nvidia, and Google DeepMind.

China, on the other hand, excels at mass industrial AI deployment and coordination which generate massive datasets. It has an extensive state-backed data ecosystem through platforms such as Tencent, Alibaba, ByteDance, and Baidu.

At India’s AI Impact Summit in February, Takahito Tokita, CEO of Japanese tech giant Fujitsu, stressed that AI must not only protect “human dignity” but also respect what he called the “dignity of data.”

Linguistic and cultural nuance is also seen as being at risk with the rise of American AI technology.

“AI solutions that are able to adapt to languages effectively become very crucial. Best practices that are tailored to individual languages can be shared among our two countries,” said Lucas Haywood, CEO of ONESTRUCTION.

What is Japan’s “Trustworthy AI” campaign?

Japan’s diplomatic campaign centers around the catchphrase of “safe, secure and trustworthy AI.”

The concept can be traced back to Japan’s 2023 G7 presidency where it launched the ‘Hiroshima AI Process’ inspired by Hiroshima’s post war legacy of international peace. The initiative seeks to develop international standards and a voluntary code of conduct for consumer and industrial AI tools.

As of 2026, 60 countries have agreed to cooperate on principles around AI safety, transparency, and responsible AI development.

But the bigger question is whether Japan can persuade the wider international community to choose collaboration over competition.
