1. Visit in late fall or early winter:
One of the best ways to keep your Japan trip costs down is to plan to travel during the times of the year when very few Japanese are traveling, either domestically or internationally. One of these times is during the period from September through November. There are few holidays of note going on during this time period, and Japanese children are in school.
2. Visit in late winter or early spring:
Another low season for Japanese travel is from later winter to early spring (February and March). Like the September through November time period, airports and ground transportation systems are not particularly crowded during this time of the year.
3. Avoid New Year and Golden Week:
On the other hand, if you want to save money you will want to avoid traveling during the New Year (last week in December/first week in January). Also, avoid Golden Week, a series of holidays that take place at the end of April and during the first week of May. During these two major Japanese holiday periods, the Japanese are out and about, which drives up travel rates and making things more congested in general.
4. Try traveling midweek:
Another money-saving tip: book your tickets for mid-week travel. Doing so can help you cut your travel costs way down.
5. Check prices with different air carriers:
Finally, check with different air carriers: you may be surprised at how much different the cost of your ticket will be when you shop around a little bit for the best rate.
