Tokyo is exactly 3.5 hours ahead of Mumbai year-round. When it's 3:00 PM in Tokyo, it's 11:30 AM in Mumbai. India uses UTC+5:30 and Japan uses UTC+9, creating a constant 3.5-hour difference.
Neither Japan nor India observes daylight saving time, so this difference remains constant throughout the year.
Optimal meeting window: 12:00 PM - 4:00 PM Tokyo time (8:30 AM - 12:30 PM Mumbai). Afternoon Tokyo catches morning Mumbai for full business day overlap.
Japan and India have growing economic ties, with Japanese automotive and tech companies investing heavily in India's manufacturing and IT sectors.
