Changes

Outside of Tokyo, less activity means less results. And there's the local gym rivalries to take in account and can be an incentive to not use such tracker. During Valentine I got 10 Chansey in one night biking through all the town (not Tokyo), while the tracker only showed one. Randomly encountered my 96% Chansey that way, and even though it might not be fair play, I definitely didn't want to share the loot with rivals, so no search spamming on that tracker.

===Shinjuku===

World's busiest train station with 3.64 million commuters on average weekday. No spawn point on the huge station (36 platforms, 200 exits !) itself. Probably removed on demand. But there's a lot of spawn points outside of the station. The area is mostly commerces, restaurants, offices, entertainment. It's a good place for urban pokemon like Porygon. You'll mostly be catching things while walking in these busy streets, so try to not bump into other people.
