Taxis in Japan
Recently, the number of available taxis has been increasing because of the Olympics. Many taxi companies have been trying to have more available taxis for tourists coming from other countries and wheelchair users.
If your wheelchair is manual or small electric wheel chair (the weight is lighter than 200 KG), I recommend you use Japan taxi. Please download the APP from the link, and you can arrange the accessible taxi and pay on the APP. There is an English Version APP as well.
Other than this service, there are the following available taxi services.
J CAR SERVICE
As for J CAR SERVICE, you can email and make a call in English.
If you have enough hands, they can bring the big wheelchair into the car.
If your wheelchair is big or electric, I recommend that you arrange a welfare taxi.
Nevertheless, I could not find any welfare taxi companies that could deal with English.
If you are OK just to go to the destination, Hitachi automobile transportation group(日立自動車交通グループ) can help you go to the place. Keep in your mind that communication could be hard since the drivers cannot speak English.
