@Theotime812 @journaling okay so!
While you can journal in a Hobonichi (I use an A5 cousin for example) you can't really write a LOT on one page.
What I would recommend, is when the store opens in september, buy either a Day-free (which you can basically use like a Bullet Journal, it does not have enough pages for you to write in every day, but you said you'd spend weeks not writing so that may work) or just buy one of the A5 notebooks they sell (I will often pick up a few myself)
In particular for the regular notebooks- the grid is smaller than you'd see in English Techos / Cousins / Weeks, etc, so unless you can write really small I would use the advice: ignore the grid. That's how I do it anyway.
