Staying at a ryokan recently, I received some postcards with the following little poem:
What are the characters that I have highlighted in red? They look a bit like [侍]{さむらい}, but based on the context clearly aren't.
Turns out this character is a fairly common ryakuji (abbreviated character) of the common honorific [御]{ご} go-, as in [御飯]{ごはん} gohan, so the full word is [御夢想]{ごむそう} go-musou, the name of the hot spring where the ryokan was located. Another example here.
