The story

The national box office rankings for October 2-4 were released, and Haruna Kawaguchi’s true-story drama “Even If Mom Is No Longer in This World: My Life’s Diary” debuted at No. 1. Based on the memoir of a young woman who died of colon cancer, the film earned 440 million yen in its first three days. Steven Spielberg’s new film “Disclosure Day” came in second. On 5ch, one thread saw comments like “terminal-illness films reliably hit no matter who makes them,” while discussion also heated up comparing attendance with other films released around the same time — including the 14th-place debut of Haruna Ayase’s “First Voice.”

October 5, 2026

The top 10 national box office rankings for October 2-4 were released by Eiga Tsushinsha (Movie Report Co.), and Haruna Kawaguchi’s starring film “Even If Mom Is No Longer in This World: My Life’s Diary” debuted at No. 1.

The film is based on the memoir of Nodoka Endo, whose story drew attention after being featured in the “Wedding Trip” segment of Nippon TV’s variety show “The 100 Million People’s Big Question!? Warattekoraete!” (lit. “Laugh and Bear It!”). Diagnosed with stage IV colon cancer at 21, Nodoka — the protagonist, played by Kawaguchi as the eldest daughter of the Kushibiki family — never lets go of her love for her husband Shoichi and their child right up until she passes away at 24. Mahiro Takasugi plays Shoichi. The director is Yuki Yamato, known for “Drowning Knife” (“Obareru Naifu”). The film earned 440 million yen in its opening three days.

Yeah, moving true-story films really are strong, as expected
3AnonymousOct 5, 2026 15:40
Heads up, Disclosure Day has aliens in it
4AnonymousOct 5, 2026 15:41
Ugh, another shallow tearjerker!
Just watch Chiikawa and be done with it! (Chiikawa — the hit cute-character franchise, also currently in theaters)
5AnonymousOct 5, 2026 15:43
Guess Chiikawa's done once the bonus freebies run out
At the end of the day it's just a merch hustle
63AnonymousOct 5, 2026 16:36
Re: #5
Bet they'll cram in new bonus goodies for the three-day weekend lol
Everyone's already sick of it though
7AnonymousOct 5, 2026 15:44
Disclosure Day was boring
8AnonymousOct 5, 2026 15:44
People just love terminal-illness movies way too much
Reliable hit every time
9AnonymousOct 5, 2026 15:44
Is this the Itakura effect?

Probably Japan national team supporters turning out as a goodwill watch (Itakura: Ko Itakura, a Japan national team defender — the connection here is unclear)
11AnonymousOct 5, 2026 15:45
Spielberg movies just don't draw crowds like they used to, huh
16AnonymousOct 5, 2026 15:48
Re: #11
Alien movies are just played out these days
13AnonymousOct 5, 2026 15:46
Guess 'Odyssey' isn't selling that well then
18AnonymousOct 5, 2026 15:48
Re: #13
It's cleared 2 billion yen
Since it's mostly IMAX screenings, it's earning more in revenue than the attendance ranking alone suggests
54AnonymousOct 5, 2026 16:28
Re: #18
So it's below Odoru… huh (Odoru = shorthand for the 'Bayside Shakedown' film series)
75AnonymousOct 5, 2026 16:45
Re: #18
Nolan's insane honestly — he's had tons of IMAX screenings this whole time and attendance barely drops, though the screening count finally did dip once Spielberg's film came out
14AnonymousOct 5, 2026 15:47
Maybe 'Mom's World' getting nitpicked over its collab is actually what boosted its attention
Honestly the complaints sounded like unhinged nitpicking anyway (a jab calling the complainers 'menhera' — slang for someone seen as emotionally unstable/drama-prone)
20AnonymousOct 5, 2026 15:49
The title is phrased like something a mom would say to her kid, but then the tagline is 'I want to be with you for every minute, every second' — feels kind of mismatched.
25AnonymousOct 5, 2026 15:51
Re: #20
Isn't it because she has so little time left that she wants to spend every extra minute with her child?
27AnonymousOct 5, 2026 15:53
Thought Avengers wasn't that popular in Japan, but even the re-release is pulling in a decent crowd
34AnonymousOct 5, 2026 16:04
Re: #27
Probably the Spider-Man effect from this summer?
28AnonymousOct 5, 2026 15:56
Lmao, Chiikawa, Spielberg, AND Odoru all lost to a Haruna Kawaguchi movie nobody even knew was being filmed
33AnonymousOct 5, 2026 16:04
Mahiro Takasugi's probably not the one pulling numbers, so it's gotta be Haruna Kawaguchi.
She's got real popularity with women too, I guess.
35AnonymousOct 5, 2026 16:05

Re: #33
The Nidec effect (Nidec — a major Japanese motor manufacturer; the joke's connection here is unclear)

Re: #1
Wait, huh?


What about the movie Haruna Ayase is all over TV promoting right now???
44AnonymousOct 5, 2026 16:18

Haruna Ayase's starring film First Voice opened at 14th place,,
56AnonymousOct 5, 2026 16:31
It's basically a miracle a Toei live-action film is pulling numbers like this
What happened
61AnonymousOct 5, 2026 16:34
Re: #56
Meanwhile, Haruna Ayase's movie…
57AnonymousOct 5, 2026 16:33
Re: #44
Lmao what a bomb
Haruna Ayase's movies really do have a lot of disastrous box office results
66AnonymousOct 5, 2026 16:39
Re: #57
They played movie scenes while, for some reason, promoting today's soccer broadcast
They'll probably do it during the soccer broadcast too
Say what you want, the promotion game is always on point
72AnonymousOct 5, 2026 16:42
Odoru's reign didn't last long, huh…
77AnonymousOct 5, 2026 16:47
Re: #72
It was only No. 1 last week
Thought it might stay on top but it dropped to 3rd
80AnonymousOct 5, 2026 16:50
Re: #72
It was No. 1 at Aeon Cinema on the weekend but doesn't even crack the top 3 at Toho — the distributor clearly knows that and keeps scheduling it in a ton of garbage time slots, kinda sad lol
73AnonymousOct 5, 2026 16:43
Suzuka Ouji's 'Beasts Clinging to Straws' is apparently hilarious but it's bombing hard
78AnonymousOct 5, 2026 16:47
Re: #73
No idea why they only gave that one a release on around 350 screens
74AnonymousOct 5, 2026 16:43
The 'based on a true story' banner is way too powerful for dodging criticism from haters
But now that I'm older, stuff like this will probably make me cry anyway
82AnonymousOct 5, 2026 16:51
Re: #74
Doesn't feel all that different to me, honestly
Back in the day I got a bit full of myself, wrote a novel, and submitted it somewhere — and that novel basically came true in real life, so ever since then I've been a believer in that kind of thing, same as any fiction writer would be

Background and talking points

The national box office rankings are published weekly by Eiga Tsushinsha (Movie Report Co.) based on major theaters nationwide, and attendance figures and box office revenue can diverge depending on how a film is screened. Titles that run a lot of premium formats like IMAX tend to earn more revenue than their attendance numbers alone suggest — ‘The Odyssey,’ mentioned in the thread, is cited as one such example. It’s also typical for roughly a year to pass between filming and release, so an actor’s current activities don’t necessarily reflect what was going on when the film was shot. The pattern of true-story and terminal-illness-themed films performing strongly isn’t unique to this case — it shows up in past hits too, and having a source memoir or a TV feature piece helps build buzz ahead of release. On the other hand, differences in release scale (number of screens) directly affect attendance numbers, so a gap between how well-received a film is and how well it actually draws crowds is a common phenomenon in this industry.
