Podcast Question - Rob's Journal System?

Hi all! I am a bit behind on the podcasts, but in one of the January episodes, Rob mentioned at the end of the episode about his new planner/journal system… He said the name of it (I think it was in Japanese?) but I couldn’t quite catch it enough to search for it. Can anyone help me out? Thanks so much!

While admitting I’m behind on podcasts, I know the Hobonichi Techo is a real popular journal people use.

Here’s his tweet about it. He says it’s a Jibun in the replies.

Perfect, thank you so much! I’ll actually look at both of these!
