This year of 2008 should be memorized as the historic year of the J-PARC opening, which has been a long dream for the Japanese neutron community for more than 3 decades. The history of the neutron science activity in Japan is briefly digested at this special occasion and then I emphasize that this world first class neutron science facility of JPARC is realized by enormous big efforts for many years. Though the road map for the world top class Japanese neutron science facility has not been completed yet at J-PARC, I strongly hope that future Japanese neutron science after the opening of J-PARC would march along the way we have drawn and walked.
