The story

In Kasumigaseki, Tokyo, in March 2025, defendant Shion Miyanishi (32) stood trial before a lay-judge panel on charges including attempted murder for slashing Takashi Tachibana (59) of the “Party to Protect the People from NHK” with a nata (a machete-like blade). On October 7, prosecutors sought a 12-year prison sentence. The defendant is a former supporter of Tachibana, and her motive is said to be regret over having voted for him. Reactions on the thread split between shock at how harsh the sentence was for an attempted crime, and others who argued that since a politician was the target, a severe punishment was only to be expected.

Guess a harsh sentence is unavoidable since she couldn't finish the job
4AnonymousOct 7, 2026 14:59
At this point it's basically just defamation of a dead man, lol.
Just let her out already — she'll probably end up with like a 1-year sentence.
5AnonymousOct 7, 2026 15:00
LOL, 12 years for an attempted crime
What kind of pull does this guy have
56AnonymousOct 7, 2026 15:37
Re: #5
Way harsher than other cases, that's wild
Well, even if she actually serves time, it'll probably get knocked down to like a tenth of that with a suspended sentence — which is a problem in its own right
13AnonymousOct 7, 2026 15:04
Is this punishment for failing to finish him off? 😗
16AnonymousOct 7, 2026 15:05
This is hindsight talking, but it was just a scratch
Attacks on politicians specifically always seem to get oddly harsh sentences
21AnonymousOct 7, 2026 15:11
Wait… the sentence wasn't being sought against Tachibana himself? 🥺
24AnonymousOct 7, 2026 15:13
Tachibana just happened not to die, but this was still an attack during a campaign speech, so
honestly, this is light
25AnonymousOct 7, 2026 15:14
Way too harsh
Is this NHK getting its revenge baked in too?
37AnonymousOct 7, 2026 15:23
Re: #25
Tachibana's all talk and never actually does anything — NHK probably doesn't even think twice about him
39AnonymousOct 7, 2026 15:26
Re: #37
Hold on, before that…
my own sentence didn't even make sense
46AnonymousOct 7, 2026 15:29
Re: #37
Maybe she's being kept in detention this whole time just because she's a nuisance
They might as well let her out
26AnonymousOct 7, 2026 15:14
Well, it does look like an attack on democracy itself. A harsh sentence is only natural
30AnonymousOct 7, 2026 15:18
I'd get it if this left lasting injuries, but for just a scratch this seems heavy — do terrorism-adjacent cases just get extra-harsh sentences?
36AnonymousOct 7, 2026 15:22
LOL, 12 years for an attempt. Guess they're desperate to keep this consistent with the Yamagami case, or the numbers wouldn't add up
41AnonymousOct 7, 2026 15:27
Re: #36
The guy who assassinated the mayor of Nagasaki also got life,
so they're probably following that precedent
43AnonymousOct 7, 2026 15:28
Apparently she regretted voting for Tachibana and felt she had to settle things herself
In the end, she made up her mind after hearing his speech the day before
It's good it ended as just an attempt — though apparently that's only because she found out Tachibana had been arrested
45AnonymousOct 7, 2026 15:28
Some people are saying 12 years is too harsh, but if you go easy on acts that attack the very foundation of democracy and the electoral system, you end up with a world where violence solves everything
62AnonymousOct 7, 2026 15:44
Re: #45
Then Yamagami should get the death penalty
52AnonymousOct 7, 2026 15:32
Didn't expect it to be this harsh for an attempt
Between this and the Abe case, don't they just hand out automatically heavier sentences whenever a politician's the target?
66AnonymousOct 7, 2026 15:46
Re: #52
When the Kansai Namacon (ready-mix concrete workers') union branch went on strike, the union leader got hit with a 10-year sentence demand on extortion charges
70AnonymousOct 7, 2026 15:49
Re: #52
Can't help it, it's a challenge to democracy
53AnonymousOct 7, 2026 15:33
Probably because if the sentence stays light, you'd get a wave of people attacking politicians
54AnonymousOct 7, 2026 15:35
She went out to kill someone — there's no such thing as 'too harsh' here
If anything, this is light
55AnonymousOct 7, 2026 15:35
Well, if the blade had landed just a few centimeters off, it probably would've hit his brain
What she did was basically murder

Background and Key Points of This Story

Attempted murder is punished in line with completed murder, and the statutory minimum sentence already starts around 5 years, making it inherently severe. Looking only at the fact that this 12-year sentence demand followed a minor injury, it can look excessive — but sentencing also weighs factors beyond the outcome, like premeditation and whether the target held social standing. That’s exactly where opinions split in the thread: some argued “it’s way too harsh for just a scratch,” while others countered that since a politician was targeted during a campaign speech, a severe sentence is only natural as an attack on democracy itself. Many posts also compared this case to the sentencing in past attacks on politicians, such as the shooting of former PM Shinzo Abe and the assassination of the mayor of Nagasaki, speculating that these precedents may have shaped the prosecution’s request. At the same time, the defendant’s motive and background are based solely on trial testimony as reported, so readers should treat these details with some caution rather than as settled fact.
