Any domestic machine incorporating a tuner will not work properly outside Japan. The wave bands assigned to AM and FM in Japan are different from the bands used in most other countries. International versions are made for very few models. If they are not listed above, they are not available on the street in Japan. Choice of colours etc. is limited, and they are significantly more expensive.
Most clients buy the domestic version and use adaptors bought at home.
If you need more insurance, consider buying your own. Once you accept my quote, I will need payment in advance. This saves international transfer costs for most people. I am an individual, not a business - I can't take credit cards no matter how gold they are. This saves you money too.
