Baby in hotels (Japan)

Hi,

We need to book three hotel stays during a couple of weeks in Japan soon. We have an 8-month old daughter.

I tried looking at prices online and one site, when I indicated one child to stay, came up with zero matches. Without the child, there were plenty. I found another site that only counted children as over 2 years.

So... do you think I should just book the rooms as if it's just the two of us (parents)? Can this cause any issues? She will sleep in the bed with us regardless.

And one stay is for a 30th birthday for my partner. I was looking at something fancy. Anyone with any experience of a Tokyo hotel that didn't faint at the sight of a young, red-headed terror!?

Thanks!

just book a room for 2 adults. japanese loved my daughter, i never had any problems.
