The subway map I grabbed in the station came complete with its own "Tokyo Sightseeing Routes," which was handy info for my guide book-less holiday. I read some of the highlights and starred my favourites: Shibuya, Tokyo Tower, Akihabara, Sensoji Temple (check), and Tsukiji Fish Market. Combined with some attractions listed in my hostel's own guidebook (Ghibli Anime Museum, Edo-Tokyo Museum, Shinjuku, Imperial Palace, Takeshita Street, and Shibuya Crossing), I realized I was in for a busy two days.
The map may have been handy, but the subway itself was a mess. The map was a colourful swirl of subway lines---thirteen in total---plus trains, a monorail, and apparently even a streetcar. Unfortunately for map users, the lines are separated into two companies with two separate travel passes, and the railways and monorail are separate as well, so you have to pay attention to your route. Not only that, but I soon discovered that the unusually high number of transfer stations weren't as beneficial as I originally thought. Too many lines parallel each other, meeting at station after station---the Fukutoshin and Yurakucho Lines have nine stations together in a row! Unnecessary. And too many stations have three, four, or even five lines intersecting together, making for long walks to transfer.
I slowly made my way to Shibuya Station, where I read there was a fashion building, ichi maru kyuu, that was the "epicenter of Tokyo fashion." But when I got there, I was quickly disappointed. The area reminded me of Gangnam in Seoul: business-like and boring. I decided to go for a walk. The most exciting thing I found was another subway station.
