Japan birding is ever changing, due largely to the ever changing seasonal patterns. So for Japan birding, the birder unfamiliar with the land should definitely consult with professionals in the field before setting off on such a trip. There is a great deal of planning when it comes to Japan birding, however all of this will be the onus of a travel agency as the trip is done as part of a birding tour. This is the preferred way of travel for bird watchers around the world. In particular, Japan birding is on par with bird watching ventures to all other areas on the planet. The thing to take into consideration here and which also places a bit of responsibility onto the birder is the time of year to visit. Japan birding is notorious for being ever changing. For first time travellers this is not much of a concern. The Japan birding factor to heed upon here is to try and not go doing the typhoon and rainy season.
This is not really because Japan birding prospects are going to be low, it is just a precaution against birders who do not so much like travelling and hiking in these conditions. The problem, however not so much a problem as a precaution, arises when further Japan birding trips are done. The dates must be of importance before confirming a spot on a Japan birding trip. A simple consult with the tour leader of the trip will ensure you of this. It simply means not going at a similar timing of your past trip, to give a whole new list of birding species to encounter during the forthcoming Japan birding tour. Any noted birding travel company will ensure not only that they lay out full details of their upcoming expeditions but give prospective tour guests the opportunity of liaising with the person who will be heading up the Japan birding trip. This is done as a sort of assurance to birders that they will be getting the full house experience of the trip, and seeing as the investment done for overseas trips, this is quite a necessary step of the process.
