Hiring a guide to Arita from Imari

My husband and I would like to arrange a tour of Arita on Wednesday, October 30, to see some of the old kilns whose work we so admire.
We will arrive in Imari the previous afternoon, October 29, but will not have a car (and would not be able to rent a car, because in Japan we are illiterate). Would it be possible to hire a guide who speaks some English to take us from Imari to tour Arita?

Regarding being illiterate in Japan, you can rent car that comes with Navi and you can change language to English. Or use google maps.
And take it slow.

You could contact the Arita tourism association to see if they can put you in touch with an English speaking guide (write your email in English, address at the bottom of the page). There is a train from Imari to Arita, which should be less expensive than meeting your driver at Imari.

I hired a guide from https://gowithguide.com/ last year during my visit. The guide was fluent in English and pretty helpful too. You can consider having a guide from GoWithGuide, or else there are other options available in this forum.

Many thanks for your thoughtful replies!
Very helpful!

Even if you can't find a hire car with English GPS, every hire car we've had in Japan had the function to put in the phone number of your destination and it will navigate you based on that. Phone numbers are pretty easy to google, and if you don't have a specific destination, then picking a landmark in the middle of a small town works just fine.

It's some years since we last did this, so I expect that availability of English GPSs has only increased, but we always got along just fine with that approach. At the start of each hire, we would smile lots and be very polite to the car hire staff as they were booking us in, and would ask them to show us the combination of buttons to press to get to the screen where you can enter a phone number for your destination, and we would film this on our phone in case we forgot. And then we would turn the car off again, and while they watched us, on of us would repeat the process (and we would film it again) - to make double-sure.

We never had a problem with this method. We speak no Japanese beyond some very basic politenesses (and a few food-related words).

Thank you very much for your kind responses to those who misinterpreted our query, but we do not want to rent a car in Japan. We admire all non-Japanese speakers who have successfully done this, but we have chosen not to attempt this.

It is perfectly fine not to rent a car :)
Although we got one later in our Kyushu trip, we visited Okawachiyama by bus+taxi (taxi to get there early morning, then we came back to Imari by bus), and Arita/Kami-Arita by train. Renting a car would have been more expensive.

We spent the day in Imari and Arita as a day trip from Nagasaki using the trains.

It was a wonderful day and relatively easy to do, using the Japan travel navitime app to know the train times
