One Piece always takes regular breaks (once every month). I don't know about any recent Toriko break, but if there was, it was most likely just a one-off thing due to the author's personal reasons. But those aren't magazine breaks, they are series break, where the magazine is still released, except the series is absent that week. Those are breaks are series-related, not because of a national holiday or some event.

If you're talking about the One Piece & Dragon Ball anime break that just happened, there was a Kochikame TV special aired in their timeslots to celebrate the end of the manga (which is the longest manga that has 200 volumes and has been running for 40 years).
