What)shoes for outside, something to drink, soap, towel, etc...
1.Get out of "the east ticket gate" in "JR Shinjyuku station". 2.Use "the east exit" to get out of the underground. 3.You can find a big road called "Shinjyuku street" in front of "the stadio ALTA", "Mitsui-Sumitomo bank", and "Mizuho bank". 4.Walk along Shinjyuku street to the opposite direction of JR railway. 5.You can find "Mitsukoshi department store" on your right side after 3 minutes.
In the case you get lost on the way, never hesitate to ask "Mitsukoshi ha doko desuka?" to the most beautiful girl on the street. I never mind if you go out with her instead of futsal as far as you prepare for Go-Kon with her friends later. See you on Sunday.
