Consequently, among the top level people in the Meiji Government who received the proposal 'to change the calendar from Onmyoryo, the pro-western civilization people argued that to move ahead with introduction of the western advanced technology and to achieve Fukoku kyohei (fortifying the country, strengthening the military), because there was a strong possibility that Onmyoryo could lead the opposition to adopting modern science, Onmyodo had be eliminated,' whereas, Shinto purists or supporters of Joi ron (principle of expelling foreigners) argued that 'by having the emperor at the top of the government, they could not allow barbaric acts such as allegiants exercising real power by going over the emperor's head or breaching etiquette, such as; allegiants dictating what the emperor should do, and, further, they could not tolerate that, despite the fact that Shinto was the tradition in Japan, Onmyodo, and an art originating from a foreign country (China) should go unchallenged,' and with both parties identifying with the arguments put forward, most of them agreed to drive Onmyodo out.
