HSP

• Reading: エイチエスピー
• Romaji: eichi esu pī
• Kanji breakdown: From English abbreviation 'HSP' (Highly Sensitive Person). Used as-is in Japanese as an alphabet abbreviation.
• Pronunciation: /e.i.tɕi.e.su.piː/

Meaning

Highly Sensitive Person — someone who is easily overstimulated by sensory input, emotions, or social situations.

HSP became a major buzzword in Japan in the early 2020s, with books, TV segments, and social media posts about the concept exploding in popularity. Many Japanese people found the label relieving — it gave a name to their lifelong experiences of being overwhelmed by noise, crowds, or others' emotions. The concept resonated particularly well in Japan's collectivist culture, where sensitivity to social cues is both valued and exhausting. Critics note that HSP is not an official medical diagnosis, and self-diagnosis through online quizzes has become extremely common.

Examples

1. 自分HSPだから、人混みにいるだけでぐったりする。 I'm an HSP, so just being in a crowd wears me out completely.
2. HSPって知ってから、自分が生きづらい理由がわかった気がする。 Ever since I learned about HSP, I finally understand why life has always felt so hard.
3. HSPの人は刺激に敏感だから、一人の時間が大事なんだって。 People with HSP are sensitive to stimuli, so alone time is really important for them.
