This was my first visit to Bungu Joshi Haku, and as someone with a basic knowledge of Japanese language, it was a smooth-sailing trip using the KKDay app. The event offered so many exclusive merchandise that you can't find even in other Japanese stationery stores, and early access to the latest items so you won't FOMO about leaving Japan before they launch in store.
If you're a die-hard stationery fan, I recommend going early so that you can get your hands on the exclusive items. Most big brands like Beverly (known for their Marumi no Fusen or round-cornered sticky notes) were sold out of their exclusive items by the afternoon. But if you're just a casual shopper looking for something fun to do, you can definitely take your time and come in later. I arrived at 2pm (the event starts at 10am) and I still managed to snag some event-exclusive items.
A fun day out indeed!
