That is an understandable concern. The announcement is in reference to a Viking settlement that you are currently running. If you want to switch to a Japanese settlement, then you must either finish the Viking settlement that you are currently doing, or abandon it.I was a little worried with the wording of the announcment because it said before starting Japan you need to either finish Vikings or abandon settlement. It just didn't seem clear to me that "finish Vikings" means the entire sequence of the upgrade/emissary rounds or just the current settlement. I'm glad we can stay with Vikings because I about 2/3ds done and want all the upgrades.
If you are not doing any settlement, then clicking on the boat will take you to the screen where you can decide which settlement to do.
