Translation guide
The English phrase "let's go" is used to suggest doing something together, to encourage movement, or to express excitement. In Japanese, the most natural equivalent depends on the situation: casual suggestions, polite invitations, or urging someone to leave. The most common and versatile option is 行こう (ikou), but other expressions like 行きましょう (ikimashou) or さあ行こう (saa ikou) add nuance.
The speaker proposes that they and the listener(s) do something together, often implying movement or starting an action.

In English, 'let's go' is often used metaphorically (e.g., 'let's go over the report'). In Japanese, use the appropriate verb instead of 行く. For example, 見直そう (let's review) or 始めよう (let's start).
行こう is casual and used with friends, family, or those of equal/lower status. 行きましょう is polite and safe for most situations. Using 行こう with a superior can be rude.
