Welcome to the Japanese Store
It is 100% authentic.
Please inquire about size, condition, and accessories before purchasing.
【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Regarding signal lines
Signal lines are used to transmit weak small signals, and small signals are susceptible to interference. Normal signal lines need to be shielded. It is recommended that signal lines be tested as much as possible. Even with very good signal lines, they can still be disturbing when using a mobile phone as a signal source.
Signal Source
The most commonly used signal sources are mobile phones and computers. The quality of the audio signals output by mobile phones and computers varies depending on the brand and model. Generally speaking, if the quality of the audio signal directly from the computer motherboard is relatively poor, it will be inaudible at low volume, but will become obvious after amplification.
If you are not satisfied with the sound quality of your computer, you can purchase a USB decoder (equivalent to an external USB sound card) from the store to improve the sound source and significantly reduce noise. It's relatively easy to determine the source of the noise: input a signal, turn up the amplifier volume, and listen to the speaker noise. If there is no noise, the noise is coming from the source or signal line.
