A thread on 5ch’s “Nandemo Jikkyo G” board compared the cost-efficiency of different hobbies: arcades supposedly burn through ¥10,000 in an hour, movies cost ¥1,000 for two hours, and fishing can fill a whole day for just ¥500.
Commenters immediately questioned the numbers themselves, picking apart the movie ticket price and whether anyone really spends ¥10,000 an hour at an arcade. The debate over fishing then split over whether to factor in the upfront cost of rods and reels, and the thread expanded to cover free alternatives like libraries and walks.

You'd normally just go fishing, right?
3AnonymousOct 3, 2026 17:37
Pachislot won't even last 30 minutes on ¥10,000
4AnonymousOct 3, 2026 17:37
Fishing seems doable even for a total newbie like me?
45AnonymousOct 3, 2026 18:02
Re: #4
There's always something to do, so it's actually perfect for newbies
5AnonymousOct 3, 2026 17:38
This is all over the place—might as well end with 'Amazon Prime kills a month for ¥500'
7AnonymousOct 3, 2026 17:39
If you're gonna go to an arcade, might as well play low-stakes pachinko instead
8AnonymousOct 3, 2026 17:39
Movies are ¥1,000? Oh wait…
13AnonymousOct 3, 2026 17:40
Re: #8
How'd you even catch that?
59AnonymousOct 3, 2026 18:13
Re: #8
Maybe it's Ladies' Day or some discount like that!
9AnonymousOct 3, 2026 17:39
If it's gonna cost ¥10,000 anyway, isn't pachinko the better deal?
12AnonymousOct 3, 2026 17:40
Are arcades really that expensive these days?
14AnonymousOct 3, 2026 17:41
How do you even manage to blow ¥10,000 in one hour at an arcade?
16AnonymousOct 3, 2026 17:41
Re: #14
Medal games and crane games, probably?
15AnonymousOct 3, 2026 17:41
Plus you save on food money too
18AnonymousOct 3, 2026 17:42
You can kill your whole life on 5ch for free, though
19AnonymousOct 3, 2026 17:43
An internet cafe is under ¥1,000 for 3 hours
21AnonymousOct 3, 2026 17:43
Re: #16
Medal games don't run out that fast, I don't think… crane games maybe though
33AnonymousOct 3, 2026 17:56
Re: #21
Back in the day there was this medal horse-racing game called Star Horse where ¥10,000 worth of medals would melt away in minutes
23AnonymousOct 3, 2026 17:43
If you spend 30 minutes on P-Free (a pachislot free-play mode) buying up random-prize tickets, you could probably hit ¥30,000 in an hour
26AnonymousOct 3, 2026 17:48
At home you can sleep as much as you want for free, and jerk off too
27AnonymousOct 3, 2026 17:50
At Arsenal Base (an arcade card-battle game), buy 5 cards and ¥600 is gone in about a minute 😊
30AnonymousOct 3, 2026 17:52
Karaoke → kills 8-12 hours for ¥1,000
31AnonymousOct 3, 2026 17:53
Chinese gacha games: 'Free, as long as you've got 1,000 hours to grind'
34AnonymousOct 3, 2026 17:56
Fishing gear is expensive though
56AnonymousOct 3, 2026 18:11
Re: #34
Rod: Fireblood Grey — ¥130,000
Reel: BB-X Technium Fireblood — ¥110,000
With this setup you can catch pretty much anything, unless it's some huge pelagic fish
35AnonymousOct 3, 2026 17:57
Library: ¥0.
Walking: ¥0.

Re: #35
That's just pathetic
36AnonymousOct 3, 2026 17:57
There's no way ¥500 kills a whole day
47AnonymousOct 3, 2026 18:04
At Yamada Denki (an electronics chain) you can play with the latest gadgets all day for free. Massage chairs are expensive, so just make it a habit
52AnonymousOct 3, 2026 18:06
Re: #47
Yamada's selection isn't even that good for how big the stores are, and there aren't many customers either
58AnonymousOct 3, 2026 18:13
Thinking about it that way, a sauna that's ¥5,000 all-in for a full day might actually be cheap
89AnonymousOct 3, 2026 18:43
Re: #58
I'm way too curious what 'all-in' covers…
68AnonymousOct 3, 2026 18:19
Even counting startup costs, it's only like ¥10,000
71AnonymousOct 3, 2026 18:22
Re: #68
For the car, are you calculating rental or purchase?
73AnonymousOct 3, 2026 18:22
Re: #71
Just the gear, nothing else
74AnonymousOct 3, 2026 18:24
Re: #73
Walking there is pretty rough though
75AnonymousOct 3, 2026 18:26
Re: #74
Transportation isn't counted as a 'startup cost'
76AnonymousOct 3, 2026 18:27
Re: #75
By that logic, travel becomes an incredibly cheap hobby
86AnonymousOct 3, 2026 18:36
Movies and arcades don't need any gear, but fishing requires equipment from the start
90AnonymousOct 3, 2026 18:46
Re: #86
Rod: ¥20,000
Reel: ¥20,000
PE line: ¥2,000
Doesn't even hit ¥50,000
If you use the rod and reel for about 10 years, that's just ¥4,000 a year
Background and Key Points of the Debate
The original format—”kills X hours for ¥Y”—is a classic nanG (Nandemo Jikkyo) template for jokingly comparing the hourly cost of different hobbies, and this time arcades, movies, and fishing were the subjects. The thread split mainly over two points. First was whether the original figures—¥10,000 and ¥500—made any sense, with posters like #13 and #59 picking apart the movie ticket price and arcade spending, while others like #14 and #16 pointed to specific ways to blow ¥10,000 an hour at an arcade (medal games, crane games). Second was the premise behind the fishing cost calculation: as the back-and-forth in posts #34, #56, #86, and #90 shows, the “one day for ¥500” claim wobbles depending on whether you count the upfront cost of rods and reels. Readers might easily assume fishing is a casual, low-budget hobby, but the thread shows gear alone can run into the tens of thousands of yen—making it a hobby that doesn’t fit neatly into a simple hourly-rate comparison.
