Sakura and Hayabusa lines valid?

Hi there!

I'm sorry the validity rules are a little confusing!

For the Japan Rail Pass, all shinkansen bullets are valid except for the Nozomi and Mizuho services. If you wish to use Nozomi and Mizuho the full charge will be applied. All other bullet trains can be freely used.

This means that the vast majority of bullet trains are available for you to use to travel Japan with a rail pass.

I think the line "the Sakura and Hayabusa lines have been proven valid" should be written: "the Sakura and Hayabusa lines are also valid"

Hope this helps!
