Both deal with the the 'supernatural', which most people can't see. Also, both develop in an episodic format, although Natsume Yuujinchou has more recurring characters than Mushishi does. The two main characters' personalities are rather different, however they're similar in that they don't hate the youkai or the mushi; They simply want to coexist with them. Both are rather philosophical stories, dabbing in the topics of life and death, and both are told with a similar slow-paced narrative, although Natsume Yuujinchou has its quick action-filled moments.
