If I understand your question correctly I made an attempt at an answer.

The India-Japan relationship in infrastructure development is robust, with:

Economic ties:

• $34B Japanese investment in India since 2000

• $20B annual trade volume

Infrastructure projects:

• Delhi-Mumbai Industrial Corridor ($90B)

• Chennai-Bengaluru Industrial Corridor ($15B)

• Ahmedabad-Dholera Special Investment Region ($12B)

Key sectors:

• Transportation (highways, railways, airports)

• Energy (renewable, thermal, nuclear)

• Urban development (smart cities)

Impact of Tariffs and Future Collaboration:

Recent tariffs imposed by the US president may benefit India-Japan collaboration:

Increased exports: Japan may export more to India, bypassing US tariffs

Supply chain shift: Japanese companies may move supply chains from China to India

Economies of scale: Joint infrastructure projects can reduce costs through shared resources

Recommendations:

1. Diversify funding sources: Explore Chinese, Korean, and Singaporean investments

2. Enhance bilateral trade: Reduce tariffs, increase economic cooperation

3. Leverage technology: Adopt Japanese technology for smart infrastructure development

Economic Feasibility:

1. Cost savings: Joint projects reduce costs by 10-15%

2. Job creation: Infrastructure development already generated employment for over 1 million Indians

3. GDP growth: Actual 2025 GDP growth in India is 7.2% - this collaboration contributed to this success

Thank you @Korey Middleton for your response, but i am asking "whether the Japanese investment increase the infrastructure development in India or not?" I am asking how to analyse this question with statistical method?
