The tuna auctions (photo below) from 5 am to 6 am are now only accessible to 120 "outsiders" in total (first come first serve basis) without the possibility of registering in advance.
As for the rest of the market, it's now only accessible to outsiders after 9 am, making it very impractical to see both the tuna auction and the market.
And about half of the market is now strictly off limits, all the time, to all visitors.
All the info is on the official site (in English), but it's pretty well hidden.
