Purchase Limit on SMBC Olive Debit Card?

I have a friend from my home country who wants me to buy a jacket on his behalf for 55万円 (not a typo). He sent me the money for it using Wise, so it’s in my Japanese bank account in Yen.

I have an SMBC Olive bank account. Would I have no issue just going in to the store and buying it with my debit card, or do I need to raise the purchase limit on my debit card first because otherwise I’ll get fraud alerts like crazy?

And if there’s anything else I need to do with my bank before buying, what do I need to do?

I’ve never bought something this expensive so I’m a little lost.
