Tokyo Big Sight is an exhibition hall which opened on Odaiba in 1996. In addition to its strange name, the complex is known for its radical architecture: four interlocking, upside-down, titanium pyramids. We approached against a tide of anime fans, all of whom were going the opposite way. A convention called Comic City had wrapped up for the day, but we noticed that the crowd was made up almost entirely of women — this convention had been dedicated to manga written for the female market. There were guys here, too, but they were all photographers hoping to get portraits of the cosplay girls. We joined in.
