Shin (しん / シン) is a Japanese reading that can mean several different things depending on the kanji used, but for martial arts, it’s usually mind (心), truth (真), or spirit (神). Here are the main meanings you actually encounter in martial arts, language, and philosophy:
Shin 心 — Heart · Mind · Spirit · Consciousness
This is the most important one in martial arts. Used in: Fudōshin (不動心) – immovable mind • Zanshin (残心) – remaining awareness • Mushin (無心) – no-mind • Isshin (一心) – one mind
In this sense, shin represents your mental state, emotional control, spiritual focus, and inner awareness.
Shin 真 — True · Real · Genuine
Used in: Shinai (真剣) – real sword • Shinken (真剣) – live blade • Shin-gi-tai (真技体) – true technique-body unity
Here shin means something authentic, genuine, absolutely real (not symbolic or fake).
Shin 神 — God · Spirit · Divine
Used in: Shinzen (神前) – in front of the gods (dojo shrine) • Shintō (神道) – the way of the gods
This refers to divine spirit, kami, or spiritual presence.
Shin 新 — New · Fresh
Used in: Shinpan (新班) – new group • Shinsaku (新作) – new creation
Here it means newness, renewal, beginning.
Shin 身 — Body · Self · One’s person
Used in: Shinshin (心身) – mind and body • Mi/te/uchi-shin concepts in some budō contexts
This refers to the physical self or embodiment.
