Honestly, the Hobonichi techno cousin would be your best bet for this: the quality of it is unmatched. You can order it from amazon, I believe, as opposed to the actual Hobonichi site and it doesn’t take too long.
I’ve also heard that the Stalogy is a good planner. But I’ve not had personal experience with it— but it’s a mock Hobonichi essentially.
If amazon doesn’t work, I’d search alternate sites like eBay or Etsy.
Have some stuff Muji coming in as well but decided to post now :)
