To use this Japanese dictionary, simply open it up and look for the word you need in the index or alphabetical order. When handling it, make sure your hands are clean to avoid further staining the text block. Try not to bend the pages too forcefully to prevent damage. For maintenance, store it in a dry and cool place. If the dust jacket or slipcase gets dirty, you can gently wipe them with a soft, dry cloth. Avoid exposing it to direct sunlight for long periods as this can cause further fading.
