This is the Apple Wireless Keyboard (JIS layout) that came with my iMac. Apple Wireless Keyboard with Japanese JIS layout, Bluetooth connection compatible. - Model Number: A1314 - Language: Japanese - Brand: Apple - Key Layout: JIS layout - Connection Method: Wireless (Bluetooth) I switched to a US layout keyboard partway through, so there is almost no key wear. However, it has been used for a considerable period, so there is a sense of use. Please check the photos. It uses batteries (2x AA), so it's recommended for those who are concerned about the battery life of rechargeable keyboards. It was only used at home, but it is a used item, so please refrain from purchasing if you are concerned. Thank you for your understanding.
