TCS Wins $1.2B Digital Transformation Contract with Japanese Conglomerate
India-headquartered TCS and Japan-headquartered Mitsubishi Heavy Industries are executing one of APAC's largest cross-border IT services deals. The contract spans operations in Japan, Thailand, and Singapore, with a dedicated Yokohama delivery center strengthening India-Japan technology ties.
Tata Consultancy Services (TCS) has won a $1.2 billion multi-year digital transformation contract with Mitsubishi Heavy Industries (MHI), one of the largest IT services deals between an Indian and Japanese company. The engagement covers enterprise AI implementation, cloud migration to a hybrid multi-cloud architecture, digital twin deployment for manufacturing operations, and cybersecurity modernization. The contract spans seven years and will involve over 3,000 TCS consultants working across MHI's operations in Japan, Thailand, and Singapore. TCS will establish a dedicated delivery center in Yokohama to support the engagement.
The TCS-Mitsubishi deal is significant on multiple levels. At $1.2B over seven years, it is one of the largest disclosed IT services contracts in APAC and demonstrates the deepening technology services relationship between India and Japan. For Japan's traditional manufacturing conglomerates, this signals an acceleration of digital transformation that has historically lagged behind Western counterparts. The scope — covering AI, cloud, digital twins, and cybersecurity — represents a comprehensive modernization rather than a point solution. For India's IT services industry, winning a contract of this scale with a prestigious Japanese manufacturer validates TCS's ability to deliver complex enterprise transformation in the world's third-largest economy. The Yokohama delivery center also creates a permanent Indian IT services presence in Japan's industrial heartland.
