The Graduate School of Economics, Seijo University was established in 1967 with the aim of fostering research in economics. Over the course of the next 50 years, the Graduate School of Economics has enabled researchers to achieve “World Class” studies in the fields of economics and business administration. In addition, through its contribution in helping students achieve their potential, many students who have gone on to become successful business executives and entrepreneurs have passed through its hallowed halls and who have made significant contribution to the regional and national economy. The spirit of Dr. Masataro Sawayanagi, in developing and growing people and his universal philosophy such as ""the most important thing in life, the foundation of all things"" has been continued to this day.

In addition to its long history and tradition, the Graduate School plays a major role in contemporary society where　globalization and ICT and network advancement are rapidly advancing. In the modern world, it is essential to constantly research, develop and acquire new knowledge and insights, whilst being mindful of the prevailing environmental and economic climate. In addition, in recent years, there has been a need to be able to respond to the natural disasters and pandemics that seek to thwart the onward development of humanity. In today's society, which has changed significantly beyond even Dr. Sawayanagi’s expectations, the "new daily life" where common sense is not so common, we must we collect data, logically interpret and structure it and determine what we need to leave, maintaining the “status quo” and what we need to redesign. Indeed, the Graduate school can be said to be a "learning place" that is the natural place to acquire the knowledge and wisdom necessary in a changing society and develop one’s logical thinking skills.
　The Graduate School of Economics opens its doors not only to students aiming to be researchers, but also to international students, working adults, and seniors, and provides professional human resources including certified public accountants, tax accountants, small and medium-sized enterprise diagnosticians, global human resources such as executives and consultants for global companies, entrepreneurs and executives and the very important entrepreneurs who have the skills to establish fledgling start-up companies. We work from Yesterday to today to tomorrow in developing our human capital to be the best it can be!

　1967年，时值成城学园成立50周年纪念之际，成城大学以培养出更多的经济学研究者为目的创建了大学院经济学研究科。在之后50多年的历史中，从本经济学研究科中走出了多位曾在经济学及经营学领域发表出引导时代的研究成果的学者。而且还有众多为日本经济发展做出卓越贡献，留名青史的经济人、经营者及创业家。成城学园能够如此人才辈出的背后，是我们一如既往地秉承着学园创立者泽柳政太郎所提倡的“所求第一义”的普遍理念的结果，而且我们还会将该精神不断地继承与发扬。
　在当今世界 “全球化发展”、“信息通信技术及互联网”的快速发展中，很多现象是用既往的“常识”、“知识”和“智慧”都无法解释的。面对社会环境的快速变化，我们也必须与其同步地增长我们的知识和见识。不仅如此，近些年我们还要面对“自然灾害、瘟疫、国际纷争”等各种阻碍了社会发展的事件。面对这些超出了人类预知能力的社会变化，既往的常识、知识和智慧都已失去了作用，形成了“新常态”的社会环境。在这样的社会环境中，每个人都要不断地增长新的知识和见识，还必须要学会如何收集信息及逻辑分析，对“何为变，何为不变”做出自己的判断并付之于行动。如此说来，我校大学院就是为您构建了这样一个对应不断变化的社会环境所需的知识储备和培养逻辑思维能力的“学习空间”。
　本研究科不仅招收有志于成为学者的研究人员，同样向留学生、社会大众、退休人员等也都广开教育之门，并积极努力地完善教学环境、提高教学质量，以培养出包括注册会计师、税理士、中小企业诊断士等专业人才、跨国企业的高管和咨询顾问等国际化人才、创业公司的创业家及家族企业的继承人等创业经营人才等，各种各样的精英人才。
