Advice on Snowboard purchase

Planning on going to Nagano, Hakuba and Myoko for give or take 14 days in February next year intermediate snowboarder. Been a few time in previous years but only ever hired gear.

I weight about 85kg/187 pounds
Height 6 foot 182 Cm

Just found an amazing deal for $200 for Boots, Binding, Snowboard and bag.

But the Snowboard is only 151 Cm. RIDE DH2 banana snowboard (151cm) 2011-12, only used for 7 days. But considering the age I will expect to get someone professional to maintain it before I head to the slopes.

Do you think this is suitable for japan/my body or should I look for something else?
