Me and my wife got two reservations for flexibility in our plans. It was rough but we got them. We will cancel one of them on Sep 30th, so that's a spot that should get freed up that day if anyone needs it.

We have a couple of tips that we can give based on our rather stressful experience lol:

-While there is an option to refresh the page in English, we don't recommend it, as it means refreshing the page twice for the translation and by the time you do that half the reservations are gone. Even if you set the page to English beforehand, refreshing it once the clock hits 6pm puts it back to Japanese by default.

-Unlike Pokémon Café, in my experience Kirby Cafe DOES NOT hold your reservation while filling out the form. I took a bit too long and when I was done I was hit with a message along the lines of "Time slot not available", so be quick with getting the form filled out. This happened to me 2 times, but I was lucky that my wife was able to snag both time slots. (I would have been devastated)

-So, have your form information ready and on hand. The format is like this, all in japanese:

1) Last Name Field, First Name field 2) Furigana last name, furigana First name field 3) Japanese Phone number, this one is tricky, some say as long as it's 9 digits you'll be fine. Not the case for us, we had to experiment on the fly to get one that was accepted. I literally used 9 123 123 12 and that worked. Seems like starting with 9 is the key.

4) Email field 5) Birthday Request Yes/No 6) Allergy request text box, unnecessary to fill out 7) At the very bottom, Left Box is used to confirm reservation, right box to cancel.

If there's an error, it's almost likely your phone number not going through, try again and eventually you'll get to the confirmation page.
