Help with website registration

Hi, I'm trying to reserve a cake in advance for my son but the site needs an account to be able to purchase.

I used google translate and the first field is for name in kanji. What should I put if I don't have a kanji name? How about the second field which I think is name in kana?

Can I use the hotel address in cases like this?

Thanks!

Seems complicated. Can you not buy a cake in an actual shop? Maybe go a few days before and reserve it?
Or as you say you have a hotel there is a phone number, could they call for you?

Unfortunately, like with many other things in Japan, the cakes are ultra limited online reservation only and I don’t think the hotel we are going to has a concierge to help us with the reservation.

On the first field, you can write your name in katakana instead of kanji. So, on the second field, you'd be writing the same thing.

@Uco thank you for the reply. Won’t it cause an issue when claiming the cake if the ID (probably my passport) I show the store has my name only in english?

the procedure to have the cakes is written in their website.

As Ken mentions, all you have to do is to show the "barcode" you get after you complete your registration.

But in any case, I don't think that your passport would cause any issues as long as it fits the katakana you use. For example, if your passport says "John Smith" and you wrote スミス　ジョン, it wouldn't cause any problems, while if you wrote ブラウン　メリー it may.

Thank you for the information. I will try to order the cakes for my kids as soon as they go on sale.
