軍師（ぐんし、gunshi）
- military strategist

The Japanese word 軍師 (ぐんし, gunshi) refers to a military strategist, a tactician, or a military advisor. A 軍師 is someone who provides strategic advice, plans campaigns, and analyzes military situations. They are typically highly skilled in military strategy, knowledge of terrain, and the deployment of troops. They often act as advisors to a general or leader, helping to make decisions that lead to victory. The role of a 軍師 is crucial in warfare and encompasses planning, intelligence gathering, and adapting strategies to changing circumstances.

⚫︎ あの武将は優秀な軍師のおかげで数々の戦に勝利した。 Translation: That warlord won numerous battles thanks to the excellent military strategist. ⚫︎ 軍師は敵の弱点を見抜き、効果的な作戦を立てた。 Translation: The military advisor identified the enemy's weaknesses and devised effective strategies.

You can use 軍師 when discussing historical military figures, military strategy, or even in metaphorical senses to describe someone who is very good at planning and strategizing in other fields like business or politics. It's suitable for formal and informal conversations, but generally used in more serious contexts due to its association with warfare.

軍師 is typically written in kanji as 軍師. The reading is always ぐんし (gunshi). There are no variations in okurigana.

⚫︎ 策略家 (さくりゃくか, sakuryakuka) - strategist ⚫︎ 戦略家 (せんりゃくか, senryakuka) - strategist ⚫︎ 参謀 (さんぼう, sanbou) - staff officer/advisor

While there isn't a direct antonym, words representing those who lack strategic ability would be the opposite. Words related to "follower" or "soldier" would also be considered as opposite in role. ⚫︎ 兵士 (へいし, heishi) - soldier ⚫︎ 愚将 (ぐしょう, gushou) - incompetent general (metaphorical)

The word 軍師 is composed of two kanji: 軍 (gun), meaning "army" or "military," and 師 (shi), meaning "master," "teacher," or "expert." Therefore, 軍師 literally translates to "military master" or "expert in military affairs," reflecting the role's function as a strategist and advisor within the military.
