〜てしかるべきだ: Should Naturally / Ought To (Moral Obligation)
Stating what's obviously right
〜てしかるべきだ is used to assert that something should be true as a matter of course — fairness, logic, or social norms demand it. It's frequently used to criticize: "this should have happened, but it didn't."
彼の功績はもっと評価されてしかるべきだ。
かれの こうせきは もっと ひょうかされて しかるべきだ。
His achievements should naturally be evaluated more highly.
Implies they currently are not — a quiet criticism.
そのような重大な問題は、事前に報告されてしかるべきだった。
そのような じゅうだいな もんだいは、じぜんに ほうこくされて しかるべきだった。
A problem that serious should naturally have been reported beforehand.
Past tense しかるべきだった = it should have happened but didn't.
Te-form + しかるべきだ
| Attaches to | Pattern | Example |

| い-adjective (くて) | Aくてしかるべきだ | 厳しくてしかるべきだ |
モチがあれだけ頑張ったのだから、賞をもらってしかるべきだ。
モチが あれだけ がんばったのだから、しょうを もらって しかるべきだ。
Mochi worked that hard, so he should naturally receive an award.

〜てしかるべきだ vs. 〜べきだ
〜べきだ states a direct opinion — "you should do X," aimed at a person's action. 〜てしかるべきだ is more detached and impersonal: it says a state of affairs should naturally exist, closer to "it stands to reason that..." It's commonly paired with passive verbs (評価されて, 報告されて) precisely because it describes how things should be treated, not what someone should do.
この制度にはもっと柔軟性があってしかるべきだ。
この せいどには もっと じゅうなんせいが あって しかるべきだ。
This system should naturally have more flexibility.
The short version
- 〜てしかるべきだ = "should naturally be / ought to be [self-evidently]"
- Attaches to: the て-form of a verb (often passive) or adjective
- Nuance/register: formal, written; often implies criticism of the current state
- Don't confuse with: 〜べきだ (a direct opinion about what someone should do)
Practice it

- 〜べき · N3 — 〜べきだ means 'should' or 'ought to' — a strong, principled obligation. Learn how to form it, すべき vs するべき, the negative べきではない, and the regretful べきだった.
- 〜てください · N5 — 〜てください is the standard way to politely ask someone to do something ('please do…'). Learn the formation, the negative 〜ないでください, softer variations, and see clear examples.
