Folding Bike on Nunobiki Ropeway

Hi!
Is this allowed? We're visiting the gardens next month. Bike dimensions when folded are 585mm high x 565mm long x 270mm wide (23" x 22.2" x 10.6")

Just checked their website and it doesn't say if it's allowed. if you want me to enquire the ropeway/garden through their webform, drop me a comment or message through my website.
