While not drastically different, the strokes might be:
* Simplified: A stroke might be shortened or omitted when it's connected to another character.
* Modified: The angle or curve of a stroke might change slightly to smoothly connect to the adjacent character.
* Connected: Strokes might be directly connected to the next character's strokes, rather than having a small space.
This is less common with printed text, where characters are often spaced and designed for individual clarity. However, it's much more common in handwritten Japanese, especially cursive styles. The changes are subtle and often learned implicitly through practice and observation.
So the answer is yes, but the differences are usually minor adjustments for better flow and readability within the context of the word.
