LSV's like this are extremely popular in the retirement home communities like The Villages in Florida. They're allowed on the golf cart paths, and also on a few roads where golf carts aren't allowed.

I have a few friends who've purchased older kei trucks. One for use on his property, the other got his tagged in NC (IIRC, it was NC). The local bicycle shop also has a kei van as their "shop truck" (another used one imported from Japan). The imports will go faster than 25mph, but they are terrible on the highway. The 25mph is an artificial limit to meet LSV regulations.

All that said, $25k isn't cheap when you can get a basic Polaris SXS for $15k. It might not be street legal in many states, but much of the usage is going to be on private property.

Farmers and universities have been picking up kei trucks for the last few years for things like groundskeeping work. Being able to sell a brand-new vehicle with parts availability to these customers is what Toyota is trying to capitalize on

Fleets, as evidenced by Toyota/Scion saying they will exclusively sell to fleet purchasers. My local university, for an example, had 20 or so Daihatsu Hijets when I went to school there, which have given way to far more expensive Ford Bronco Sports and similar. I assume the lack of parts supply and repairability of the Hijets attrited them away. Domestically producing them to keep the chicken tax/tariffs at bay and having dealer service at the local Toyota dealership will make these appealing again in those markets.

It also seems like it'd be a really good city pickup truck.

A friend with a WFH tech job, who lives on his own land (with family and various critters), bought one a few years ago for hauling materials and supplies around his property.

“This makes it not really usable as a daily driver, but keeps it in this beautiful sweet spot where it has a shocking number of commercial and agricultural uses.”

In rural Iowa I saw a ton of those little "UTV", gators, or whatever various brands call them which are effectively beefed up golf carts being driven around town. Trucks have become so enormous and expensive that these somewhat street legal vehicles are taking over for people who just need to go here and there.

Farmers or land owners. Great for hauling around your property. Like a 4 wheeler with a trailer but road legal.

You do see people taking tractors on roads between farms pretty often, and they usually have the speed limit stuff on.
