Rakuten Bank advice

[Utachiyo]

I'm in the process of opening Rakuten Bank accounts for both myself and my daughter, for our savings. The interest rates (while still not great) seem better than the usual brick and mortar banks. I also have a Rakuten Securities account, which means I can link up the accounts and get a better interest rate. BUT, I just want to check with everyone here to make sure there's no fine print I'm missing. For example, if I link up my bank account and securities account, are there any requirements beyond that (making a certain amount of securities transactions or something)? I'll probably stick my daugher's money into a teiki yokin account. There seem to be a few choices with that, but I don't really understand them. Any ideas?
I dont have a native Japanese speaker/reader around, so I always feel a bit nervous that I'm going to miss something important.

Not that I am aware of...

You can have a Rakuten Bank account and a Securities account and make 0 transactions. Or even choose to fund your Securities account through other banks such as JP post etc.

Exactly. Linking your accounts just makes it easy to move money around. No other strings attached.

Thank you!! Now, I just have to wait for all the account paperwork to go through.... Gives new meaning to the term "snail mail"!
