Alternative Tokyo Rail & Subway Map

Via this Japan Times article, I bumped into Vollmer Design's great looking alternative Tokyo Rail & Subway map. The goal was to make the map fit better with long romaji station names, but in my opinion, certain names crossing subway lines could use an outline or dropshadow to improve the contrast. The "ei" in Seibu-Shinjuku for instance is almost unreadable in the online version. Otherwise, a very nice project.
