Tickets of the 40th anniversary of the Sanyo Shinkansen whole line opening

Hello.
This is May in Japan.

I went for a one-day trip to Osaka last week.
The distance in a straight line from Fukuoka to Osaka is about 430Km.

I usually go to Osaka by staying overnight.
But this time, I got a bargain ticket of Shinkansen, so I went for a one-day trip to Osaka.
 

The tickets were bargain tickets of Shinkansen.
It was the tickets of the 40th anniversary of the Sanyo Shinkansen whole line opening.
These tickets was sold time-limited, because the Sanyo Shinkansen became the whole line opening 40th anniversary in this year.

The normal price of the Shinkansen is 14,450 yen from Kitakyusyu(Fukuoka) to Osaka by one way.
But it costs 5610yen by one way !!
It is surprisingly cheap !!

I went for a one-day trip with this ticket to Osaka

I'll introduce the one day trip to Osaka, next time....
