Kaibunsho are not entirely uncommon in Japanese society for a couple of reasons.

1) Libel and slander laws in Japan are oppressive. If you expose or say something unflattering about someone, you can be sued for damages even if what you are saying is true! This means that any real expose must be made anonymously for reasons of self-protection, and one of these ways is the kaibunsho. This is not to suggest that most kaibunsho are true, and of course even those based in truth have some agenda. However, the fact remains that kaibunsho are one of the methods used to air grievances or bring otherwise unknown information to light in Japan, and readers are left to their own judgment as to the accuracy or motives.

2) Japanese culture in general tends to have difficulty keeping secrets. For example, during the post-war occupation, General MacArthur was known to remark in frustration at the inability of Japanese government officials to maintain confidentiality. The Japanese love to gossip, and there seems to be some compulsion to emphasize status and privilege by privately divulging secret information. This compulsion appears to be particularly strong among bureaucrats and otaku for whom information is a form of currency and a kind of control or status*. However, it should be noted that this flaunting of secrets is generally limited to one's extended "in-group", and rarely are de-facto truths (dirty laundry) that "everyone knows" within an insular group publicly aired outside the group.
