I did hatsumode back in 2013: we all walked from A-Button to Kanda Myojin shrine at midnight. The line to make an offering was stunning and I didn't feel right taking up someone's place; we just proceeded to the gyoza and Asahi being served in the back. My phone battery ran out on the way back and I walked basically across the length of Okachimachi in the wrong direction before figuring out that "Shin-Okachimachi" and "Naka-Okachimachi" were different places. Then I was kind of hung over and sick for the rest of my vacation, as you might have imagined.
Ah, I miss Japan.
