The pulsed neutron source, JSNS, in J-PARC will be one of the most intensive neutron source in the world. After 7-year construction since 2001, it has started commissioning since May 2008 to be a user facility from December 2008. The first neutrons were created in 30 May this year, and more than 10 instruments are under construction or in commissioning. 1 MW in the acceleration power will provide very bright neutron flux, which is about 1,000 times in intensity from the previous neutron source in Japan. We expect an occurrence of a large stepwise development in neutron sciences not only on high pressure science but other large number of sciences in the near future.
