Since my last update, I’ve tried searching for sites or specialized shops where I could buy a RAC adapter, but I’ve had no luck. So, I turned my attention to second-hand websites like eBay and Yahoo Auction, as well as classified ads sites. I’ve been checking them every day for the past month.

I did find one brand-new RAC adapter on sale on eBay France for about 110 euros, but it doesn’t seem like it’s possible to have it shipped to Japan...

Last week, I reached out to people around me, and a former work acquaintance put me in touch with someone from a small company that supplies LED lighting fixtures and air conditioning systems to corporate clients. The quotation I received from them was quite expensive: around 25,000 yen.

I’ll try contacting that French seller on eBay, and I’m also planning to reach out to Hitachi directly to see what they can offer.
