Wakarimasen vs Shirimasen One of my main vocabulary words this week is utilizing "wakaru" (understand) わかる When we do not understand we use Wakarimasen or Shirimasen. I am trying to figure out what the best time to use shirimasen vs wakarimasen. From my understanding Shirimasen is a bit more informal. So if we say this in all situations we may be implying "do not care to know" or "who knows". For now until I am more fluent in Japanese I will use wakarimasen to be safe. I will revisit shirimasen once I ask a few friends from Japan. O-yasumi nasai. お やすみ なさい
