Best private car service from Osaka → Takasaki (Gunma) for 6 people with luggage?

Hi everyone,

I’m planning a trip to Japan this summer and I’m trying to figure out the best way to arrange transportation for my family.

We’ll be traveling from Osaka to Takasaki (Gunma) and there will be 6 people plus several large suitcases. Because of the luggage and group size, we’re thinking a private van or car service with a driver might be easier than taking trains.

Does anyone have recommendations for reliable private transfer companies in Japan that can do long-distance trips like this?

Ideally looking for:

• A large van (Toyota HiAce / Alphard / similar)

• Space for 6 passengers + multiple suitcases

• English-friendly booking/driver if possible

• Door-to-door pickup in Osaka and drop-off in Takasaki

I’ve seen some options online like chauffeur services and transfer sites, but it’s hard to tell which companies are actually reputable. Some services offer vans or minibuses specifically for 6–9 passengers with luggage, depending on vehicle size. 

If anyone has used a company they liked (or knows typical pricing for this route), I’d really appreciate the help!

Thanks!
