• Synonym熱心ねっしんNeutralZealous, enthusiastic; a na-adjective for devoted, diligent effort. About taking a task seriously, not about intense feeling.
• Synonym熱気ねっきNeutralHeat or a charged, excited atmosphere; points to the mood of a place or crowd rather than passion within one person.
• Synonym激情げきじょうNeutralViolent, surging emotion that can be positive or negative and often borders on losing control; not necessarily love for something.

• Related熱誠ねっせいWrittenWritten and rare; sincere, wholehearted devotion to something, as in 「熱誠を込めて」. Sincerity, not the fierce heat of 熱情.

• Related忘我ぼうがWrittenWritten word for being so absorbed you forget yourself, as in 「忘我の境地」; a state of mind, where 熱情 is the emotion itself.
• Related客気かっきWrittenWritten and rare; the impetuous ardor of youth, tinged with rashness, whereas 「熱情」 carries no such reckless edge.
• Antonym冷淡れいたんNeutralColdness or indifference, showing no enthusiasm; the direct opposite of the wholehearted warmth of 熱情.
• Antonym無関心むかんしんNeutralApathy, having no interest in something at all; the opposite of 熱情, which is passion poured into something.
• Antonym冷静れいせいNeutralCalm and composed, unexcited; the opposite of the heightened emotion of 熱情.

For everyday passion, say 「情熱」; 「熱情」 is more written, common in literature and music. For drive and earnestness use 「熱意」 or 「意気込み」; for devotion to a task, 「熱心」 or 「熱中」. Use 「熱狂」 for fan frenzy, 「激情」 for violent emotion that may boil over, 「熱烈」 for ardent welcomes or support, 「熱気」 for a charged atmosphere, and 「パッション」 as a trendy loanword. 「冷淡」, 「無関心」 and 「冷静」 are the opposites.
