Golden Week

Golden Week is one of the week in which national flag holidays are concentrated.
Here is this year's schedule.

1.April 29: *Maemorial day for Showa era, which was originally the birthday of Showa Ten nou
2. April 30: Saturday
3. May 1: Sunday
4. May 2: Monday:this is ordinal day. We should work!!
5. May 3: Constitution Day
6. May 4: Green Day
7. May 5: Kid's Day
8. May 6:Friday:this is ordinal day. We should work!!
9. May 7:Saturday
10. May 8:Sunday

So, if you take 2 days day-offs,  off-work day could be 10 days in a row. If this year's is an ordinal year, Golden Week should be the most busiest week for travel industry. But because of the earthquake, it is expected that the people who have plan to travel is 25% fewer than preveious year. Then, many hotels and travel agencies are doing special campaigns by reducing  price, to encourage people to travel.
(And those hotels in Japan can not expect travelers from other countries, which they claim is one of Huu hyou higai.)

Anyway, the travel angencies are eagar to stimulate the people to go travels.
So, still you may be able to find special offerings.
