Japanese for aikido

The terms that come up constantly in an aikido dojo: roles, entering and turning, the main techniques, and the etiquette words spoken at the start and end of practice.

Aikido leans on its Japanese vocabulary more heavily than most martial arts, and many of the words describe a direction or principle rather than a fixed move.

Roles and the basics

nage / uke
The one who throws / the one who receives
ukemi
Breakfall - how you receive safely
keiko
Practice / training
dōjō
Training hall
Why it works

うけみ is arguably the first real skill in aikido: you spend as much time being thrown as throwing. The word means “receiving body” - it frames falling as an active skill rather than a failure.

Movement principles

irimi
Entering - moving in toward the attack
tenkan
Turning - pivoting away from the line
ma-ai
Distance / spacing between partners
zanshin
Remaining awareness after a technique
Why it works

いりみ and てんかん are the two halves of nearly every aikido technique - you either enter or you turn. Instructors often name a technique by which of the two it uses, so catching these two words tells you the shape of the movement before you see it.

Common techniques

ikkyō
“First teaching” - the first controlling technique
shihō-nage
Four-direction throw
kote-gaeshi
Wrist turn-out
kaiten-nage
Rotary throw
Why it works

いっきょう through ごきょう (ikkyō to gokyō) are literally “first teaching” to “fifth teaching” - the numbered core controls. When you hear にきょう (nikyō) you know it's the second in that series, which is a helpful map of the syllabus.

Start and end of class

seiza
Formal kneeling posture
mokusō
Silent meditation
onegaishimasu
Said to a partner before practising
arigatō gozaimashita
Said after practice
Why it works

あいきどう breaks down as あい (ai, harmony) + き (ki, energy/spirit) + どう (dō, way) - “the way of harmonising energy”. It's a fair summary of what the techniques are trying to do: blend with force rather than meet it.
