Translation guide
The English word 'hardcore' has several distinct meanings: extremely dedicated or intense, a genre of aggressive music, explicit pornography, and a literal building material. This guide covers the most common uses for learners.
Describing a person, activity, or thing that is extremely committed, serious, or intense, often to an extreme degree.
Literally 'reinforced with metal wires', this is a common and natural way to describe a person who is a hardcore, dyed-in-the-wool something (e.g., a hardcore fan, a hardcore conservative). It emphasizes unwavering dedication.

While ハードコア is understood, using 筋金入り is often more natural and idiomatic for describing a person's unwavering dedication. ハードコア can sound like a direct loanword and may not fit all contexts.
筋金入り implies a long-standing, almost inherent quality (like 'dyed-in-the-wool'). ハードコア emphasizes intensity and extremeness, often in a subcultural context. Choose based on nuance.
