Nobita and his friends have gone undersea, and Indian audiences are following. Doraemon: Castle of the Undersea Devil is holding steady in its second week, and according to Pinkvilla it has already become the biggest grosser of the franchise in India.

For series background, see Doraemon on Wikipedia.

Doraemon: Castle of the Undersea Devi- Box Office

Detail	Figure
2nd Friday	Rs 1.25 crore
8-day total	Rs 14.75 crore gross (India), per the report
2nd weekend projection	Rs 17-19 crore gross
Franchise status	Biggest Indian grosser of the Doraemon films

How the First Week Played Out?

Day	Gross (Rs crore)
Day 1	2.90
Day 2	2.60
Day 3	3.75
Day 4	1.25
Day 5	1.75
Day 6	1.25
Day 7	1.25
Day 8 (est.)	1.25

The pattern is classic family-film behavior: a strong opening weekend, then a steady weekday floor of about Rs 1.25 crore. There are no dramatic drops, and that consistency is the real story.

A quick caution: the daily figures above add up to a bit more than the Rs 14.75 crore total quoted in the report, so treat the exact numbers as estimates and check for updates.

What’s the Movie About?

Nobita and friends head out on an undersea camping trip using Doraemon’s gadgets. Their adventure leads them to the hidden Mu Federation, where they learn that Poseidon, a rogue AI from the ancient Atlantis civilization, has activated a weapon that could destroy Earth. Together with Mu’s El, the group ventures into the Bermuda Triangle to stop it.

Why the Steady Run Matters?

Factor	Why It Helps
Family audience	Kids and parents tend to watch together, which supports weekend crowds
Low weekday drops	A Rs 1.25 crore floor suggests loyal repeat demand
Franchise strength	Doraemon is a household name in India

Reports note that earlier Doraemon films didn’t reach these numbers in India, which makes this release a milestone for the franchise.

What to Watch Next?

The second weekend. The projected Rs 17-19 crore gross will show how much steam is left.
Competition. Bigger releases may reduce screens, so watch week three.
Holiday boost. Festival periods often help family films, though I haven’t seen a confirmed forecast.
