テンション

てんしょん
noun
mood, energy level
1. mood, spirits, energy level
One's level of excitement, enthusiasm, or emotional energy. High tension means being upbeat and energetic; low tension means being down or unmotivated. This is a wasei-eigo usage distinct from the English meaning.

You seem down today.

2. tension (English meaning)
Physical tension, tightness, or stress (the original English meaning). Less common in everyday Japanese than sense 1.

To adjust the tension of the rope.

The tension on the guitar strings is too high.
テンションをかけすぎると(いと)()れる。

ETYMOLOGY: From English "tension," but used with a different meaning in Japanese (和製英語(わせいえいご)). In Japanese, it primarily refers to one's mood or energy level, not stress or tightness.

CAUTION FOR LEARNERS: In English, "high tension" suggests stress or anxiety, but in Japanese ハイテンション means "excited" or "energetic." This is a common source of misunderstanding.
