They say a special deal is now available for those "usual" cars which hold an ETC system. Huge cars like tracks, buses are exception.
You only need to pay 1,000 yen when you drive rural/country toll roads on Sats, Suns and national holidays. But this does not seem so simple, while I try to check the fee through this site ( Sorry, only in Japanese! ), it says
Hachioji (Tokyo) --> Toyoshina : 1,000 yen
Nagoya --> Toyoshina : 1,950 yen
Suita (Osaka) --> Toyoshina : 2,250 yen
It does not seem that 1,000 yen applied to every case. Anyway perhaps this could be a good news that now cheper fee is available. But on the other hand, ferries seem to have hard time due to this price competition. Some ferries might be out of service in the near future because some ferry companies won't find there's any business profits any more. JR (Japan Rail ) won't care the old lines along the new Shinkansen (bullet train ) line when it will get in service.
Probably I guess if we get some convenient services, we might lose something else. There won't be wide choices available any more, then.
