It's open until 9 PM, and its rates are among the cheapest in Akihabara. However, the parking lot is small. While all the cheapest parking lots in the area were full, I happened to pass by this one and found a spot available, so I was able to park there. I thought it would be a mechanical parking lot, but it turned out to be a huge elevator - I had to take my car to the second basement floor and then park it again in the multi-story parking garage, which was an interesting experience. You have to leave the parking lot by 9 PM, but since few stores in Akihabara are open late, this shouldn't be a problem. I've seen posts saying that once you park your car you can't get back in, but in fact I was able to. I was in a hurry and didn't realize I'd left my car keys inside, so I went back a few hours later and was able to check inside my car. It's located in the basement of Radio Kaikan, but please note it's not directly connected to the store.
