<General>
1. Usually, the JASDF release their open house schedule at around 20th March every year.
( They release only the date before July, but in these 2 years, they release almost all airshow schedules in early Apr. )
2. Usually, the JGSDF release their open house schedule at early March, because they open their camps at the season of the cherry blossoms(early April) to see.
3. Usually, the JMSDF release their open house schedule about 1-2 month before the event.
4. JASDF/JGSDF/JMSDF are "holiday" on Sat. and Sun. and the National holidays in Japan.
Date of the National holidays are changed every year, so please check them every year(or when you start to think your trip to Japan).
There are no activities except routine maritime patrol, exercise, emergency and /or some special missions.
There are some holidays continually from 29 Apr. to 5 May, so we Japanese call the period as "Golden Week".
There will be no flights In this period (and plus 1-2 days for Sat. and Sun.).
In 2025, it will be from 26 Apr. to 6 May..(I think, there will be quite limited flights on 7-9 May.)
5. There are also No activities on these days;
1) The day of the local school examinations.
2) The day of the Flying Safety in JASDF which is usually 1st. Jul..
3) The year-end and 1st week of the new year(usually, around 25 Dec to 6 Jan.)

4) "O-bon" period, usually around 12 Aug. to 16 Aug.. In 2025, it will be 9 Aug. to 17 Aug..
5) The next day of the airshow or the open house day, except QRA and the transportation flight.
6. Japanese financial year starts on 1st.Apr. and end(close) 31 Mar. It is important !
There are quite less flight from the 3rd. week of March to the The 1st. week of April(around 15 March to 3-4 April).
Because the end of March marks the end of the financial year in Japan.
They used up their budget (including fuels) for the financial year, and maybe busy to write up /finish their paper-works.
They are also busy for the first few days of April, because new financial year starts 1 Apr. in Japan
This means a lot of "old" organization close on 31 Mar. and establish "new" organization on 1 Apr..
So there are a lot of personnel movements, and relative ceremonies at this season.
In 2025, it will be from 20Mar. to 06Apr..
