This was one of my favourite shows when I was a small boy and still is but too bad I can't seem to find it anywhere. Not surprising since the show's first series goes way back to 1968 (no, I'm not that old!) which was then followed by other series in 1971, 1985 and 1996 (this was probably the one I saw a few episodes of). So, I'm glad that it's back with a fifth series starting on April Fool's Day! How fitting for the show's theme!

I guess I'm interested in these Youkai found in Japanese mythology.

Copying from the Kitarou GBA game guide I wrote back in 2003...

The story is based on Kitarou, a boy who's Youkai (demon) parents died and now travels with an elderly one-eyed Youkai named Medama. Long ago, the Youkai had lived together in harmony on earth until humans were born. Afterwards, the humans forced the Youkai to go into hiding. As time passes, some remained peaceful and lived through their days quietly. But, some were not content with the way things were and decided to get vengence on human kind. It is here that we follow the adventures of Kitarou as he settles matters with his other Youkai friends.
