The insulators between the metal hot chassis and the metal cabinet is standard practice for TVs and radios and is critical, otherwise the cabinet would be always be hot. The same goes for the screws that would anchor a hot chassis in a non-metallic cabinet.

Different countries have different electrical codes that products must adhere to,
that explains the two fuses.

Some of Japan has 100V and other parts have 110V. Originally it was all 100V.
Due to all the destruction of WWII and the help re-bulding the US did afterward, the new electrical generation in some area followed the US standard of the time. Another aspect is that the 100V system runs at 50Hz and the 110V system runs at 60Hz.
