I've never tried myself. Perhaps you could ask a friend who lives in Japan to buy on your behalf? I don't think it's possible to buy direct from a Japanese dealer and send to US. I do get rather envious of what is generally available for JDM customers!
I believe there are users in the Gen 3 mods forum who get JDM parts. It might be worthwhile looking there and PM some of them.
SOme of our older vans had a top hinged door. A strap (as mentioned earlier) is easy to create by yourself: I have a similar problem. My mother can't reach the antenna on my CT, so she had to skip a car wash. She does not want to stand on the rear wheel, and luckily the latest version does not have this silly antenna.
A 5 dollar plastic step stool kept in the back would work too Something like this http://www.medwaysplastics.co.uk/images/H2321x---40cm-Stool.jpg
You could attach a pull strap. (I agree that you shouldn't have to. ) Posted via the PriusChat mobile app.
I noticed right away that my '13 has two handles since the '05 had and the wife's '07 has only one. I still habitually use the one on the right even though I'm left handed. By the way, I just used the hanyman's secret weapon (duct tape) to attach a strip of old carpet to the garage door hardware to keep the spoiler from resting (or sliding) against it. I still plan to restrict the hatch travel soon though because I have visions of forgetting and operating the garage door with the hatch open. I saw in the service history of this car that the spoiler has already been replaced once. I wonder why. LOL!
Straps like these could be looped around itself around the hatch handle: 18” Blue Tie Down Extension Soft Touch Loops Straps 4500lbs Motorcycle ATV | eBay They come in many different colors (black) too.
Yeah, that would be a concern. Perhaps a bit of Velcro could be attached to the inside of the hatch to secure the end of the strap once the hatch is pulled down and in hand.
If you mount the strap the same distance up the hatch door as its length, it will tuck itself in. E.g. if you make a 12" long strap, mount it 12" up from the bottom of the hatch door, i.e. 12" forward when the hatch is open. A little less leverage but just as easy to grab.
