Time Zone, Tokyo

Almost every traffic in Tokyo gets too heavy within these time zone.7:00-9:3017:00-19:00I mean almost all. Both railways and roadways including The Metropolitan Expressway.
Every train will get difficult for you travellers to ride on because it will be jam-packed. You will feel like as if you are a grain of rice in a sushi roll.
A car won't move and you will see the tail lamps of the preceding car lightning red all the time.

Unique Suggestions: Just avoid to get on a train and to get in an taxi or a bus between those rush hours on a weekday.

Fun Alternatives: Walk!

If you pass this station or any main stations at the rush hours.

You are well traped with the crowds just walking past you like as if you don't exists next to them.
You will be pushed by the commuter and by the platform crowd controllers.

Unique Suggestions: Try it your self and just experience the fun.

Fun Alternatives: There is non, or you take it or leave it and stay at home,

Another way to do it is take the fisrt train normaly at 4.45AM, or travel off peak after 11AM. by then you have lost the whole day.

Do remember to check the closing time if you stay in a hostel. If you are late back to the hostel, you will be in trouble. I had this experience. My friend and I tried to find a hourly room along the street, no one gave us the offer coz they suspected we were lespians who wanted to rent a room for 'that'! Then, we just sat in a coffee shop overnight. And there are not too many coffee shops run overnight.
Funny!
