Aerial view of the launch area in Sanriku

The Sanriku balloon center (SBC), was until 2007 the only permanent facility of its kind in Japan able to perform stratospheric balloon launches. It was located in the northeast part of the country, in the Iwate Prefecture on the Pacific Ocean shore, and about 230 meters above sea level in a valley surrounded by mountains.

The facility was operated by the Japanese space agency (JAXA) and was inaugurated in November 1971, concentrating there all the scientific balloon missions that were performed since middle 60's decade from a temporary site established in Taiyomura Prefecture, near Ibaraki and then from Haranomachi in the Fukushima prefecture.

The center counted with a rather small launch area measuring only ​​150 meters long by 30 meters wide, thus to perform the balloon launches was mostly used the vertical technique launch. It also had a complete control center, a hangar for the integration of scientific gondolas and a tracking and telemetry station located in a nearby hill.

Since its opening in 1971 almost 500 balloon launches were performed there ranging from 1000 m3 to 200,000 m3 of volume. Operationally, Sanriku had the uniqueness that all the flights were carried out over the Ocean. Thus the payloads flown were water-tight and also were recovered from the sea surface.

New launch system using a movable platform

To avoid an excessive short flight period due to the withdrawal of the balloon from the base, it was developed a flying technique called "Boomerang": the balloon was launched and flown on a steady course below 20 km of altitude, at that level, the air currents pushed him toward the ocean until reaching the desired turning point. At that moment a certain amount of ballast is released, to let the balloon rose to an altitude of 30 to 40 kms where it was taken by the air currents in reverse direction back to the coast.

In 1998, extension works of the launch pad were made and a new platform fixed to the ground for lifting payloads (right) was installed in the added surface.

This new "semi-dynamic" method allowed for some time to use balloons of larger volume as the platform revolved around its vertical axis and was possible to direct the train in different directions at launch, as well as raise the gondola up to 5 meters above the ground. Theoretically, these improvements would permit the launching of balloons up to 1,000,000 m3 of volume. However, the growing population density in the area and the lack of space forced to move operations to a more open place. Thus in September 2007 was launched the last balloon from Sanriku and was held a ceremony to close the center.

From that moment on, the balloon operations moved far north to the Taiki Aerospace Research Field located in the Hokkaido Island.
