What does it mean word for word?
The phrase is composed of mou (already/now), ika (the stem of the verb to go) and nakya (a colloquial contraction of nakereba naranai, which means "must" or "have to").
Which one should you use?
You may also encounter ikanaito, which is another common way to say "I gotta go" in casual settings using a different conditional structure.
Is there a formal and an informal way to say it?
もう行かなきゃ is highly casual and should only be used with friends, family or peers. It should not be used in professional or formal settings. In formal situations, to express the need to leave, you should use O-saki ni shitsurei shimasu, which means "Excuse me for leaving before you".
How does it change in a sentence?
もう行かなきゃ is a shortened, colloquial version of the grammatically complete form 行かなきゃならない (ikanakya naranai).
How do you pronounce it?
mou ikanakya
When do people say it?
When leaving a group of friends, you might follow your departure with an informal phrase like Jaa, mata ne, meaning "Well, see you later".
Did you know?
- While もう行かなきゃ signals a need to leave, Japanese speakers often use the phrase そろそろ to gently hint that they are thinking about leaving long before they actually say the words.
- The formal alternative お先に失礼します literally means 'I am being rude by leaving before you', reflecting a cultural priority on group harmony over individual schedules.
- Depending on the region, speakers might use 行かんと instead of 行かなきゃ, a characteristic of the Kyushu dialect that changes the grammatical ending of the 'must' construction.

- ごめん、もう行かなきゃ。gomen, mou ikanakya.Sorry, I gotta go.
