Where in Tokyo can I sell/give-away US electronics (specifically home appliances)?

I lived for a short time in the US about 3 years ago and had some home appliances (a electric wok, electric kettle, two electric blenders) bought brand new. But had to move back to India immediately so I didn't get a chance to use these appliances. I figured I'd go back so I brought them with me to India.

I couldn't use these appliances in India because our electricity is 220v-240v. I don't see myself or anyone I know going to US anytime soon. I tried selling it online in a group where students who were aspiring to go to US for studies but nobody got back to me. I think it's generally a hassle for them to carry stuff from here when they can buy it easily over there.

I know that in Japan, US electrical appliances work without much trouble. I will be visiting Tokyo in August. Is there any place in Tokyo where I can go and sell off these US appliances? Even giving away for a good cause would do. These appliances are brand new (with exception of blenders which I've used a couple of times) and have never been used.
