Snow in Early April - Clothes?

Hi! We'd like to see and touch snow during our trip to Japan this March 28-April 5. After searching a bit online, our best option I think is Gala Yuzawa.

But our problem now is whether we need to bring winter clothes with us? We really don't have any as we live in a tropical country. But we're also not planning on skiing there. We just want to ride the gondola and do some sightseeing. Should we still rent stuff there?

Thanks!

No need special winter close if fine and no strong winds day.
Just don't rolling on and walk to deep covered area if will be wet make body cold.

BTW,read ur prifile using Seishun 18 kippu aready.
Why no using this time to other snow covered area?
