Feb 28, saturday morning, I took a 8:30 flight to boston logan airport,
At 12:30, I flew japan airline jal007 to tokyo narita,
Keisei train to ueno, 1030 yen,
There, I got confused, I bought a jr ticket and tried to use tokyo metro,
Could not get in, could not found jr line's entrence,
So I had to buy a metro pass, tabanacle,
3 stops cost me 140 yen + 170yen,
