Nuances and Register
"際" is more formal than simply using "とき" (when). It is often found in written Japanese, official documents, and polite speech. Using "際" adds a sense of formality and specificity to the timing.
Common Mistakes
Learners sometimes confuse "際" with "時" (とき). While both can mean "when," "際" is more formal and used for specific occasions or events, often in official or polite contexts. Avoid using "際" in casual conversation where "とき" would be more natural.
