PLANET is a neutron beamline dedicated to high-pressure experiments constructed at BL11 of the Materials and Life Science Experimental Facility (MLF) in J-PARC. As the first high-pressure neutron beamline in Japan, the beamline was opened to the public in 2013 in response to everyone's expectations. The objectives of PLANET (in my opinion) were: i) to create an environment where high-pressure neutron experiments can be performed routinely in Japan, ii) to lower the barriers to high-pressure neutron experiments, and iii) to establish high-pressure neutron research in Japan through these activities. In conclusion, we have achieved No. i), but we still have a long way to go in the others, and it is difficult to say that a neutron culture has taken root in Japan in terms of the scale and content of users. In this presentation, I would like to look back the past and the present, almost 10 years after the start of operation, and consider the next 10 years to achieve the above objectives.
