I purchased this item during a trip to the United States about three months ago and have been using it to watch videos since returning home. However, after storing it without charging for a few days, horizontal lines appeared on the screen when I used it again. The overall condition is good, and the damage appears to be an internal malfunction, not caused by external factors. Since I purchased it overseas, I cannot claim warranty, so I am listing it for sale. Japanese language support is available. The item will be shipped as the main unit only.
