Love the dictionary entries xD. I do translation sometimes and when coming across words I don't know I often get dictionary entries that just direct me to another entry which then direct me back to the previous entry. Who came up with that nonesense?! xD
I also heard that while there's sex ed in schools in Japan, the quality of classes is usually bad because the teachers are too embarassed to teach, so they often just show a(n oudated) educational video and done.
