Mini bus rental in Hakata

Hello, my family and I (10 pax) will be travelling to Kyushu in January and would like to rent a mini bus.

I've checked tocoo / budget websites and their hiace have a capacity of 10 and recommended capacity of 7. We have rented hiace in other countries where the capacity is 13 and am wondering if Japan has the same type of rental?

It would be great if someone could share and recommend any website for mini bus rental. We will obtain the Class D IDP before our trip.

Thanks in advance!

When i do a search, gToyota Hiace wagon grand cabinh appears on some rental companiesf websites as 10-passenger vehicle. The classification is W4, OK with a regular driverfs license. Another one is Nissan NV350, which might be classified as W5 even.
