How difficult is it for a software developer from India to get a job in Japan with no job experience?

First come to Japan for a long visit to make sure that you like the country and culture. Try to live your life as you normally would at home and see if the compromises are within your allowances. Spend as long as you doing that because the culture may not match your personality, expectations or whatever. If you like  living in Japan enroll in a Japanese language school to get a visa that would let you work part-time. Apply to an outsourcing company to get part time work within the time allowed for your visa. Don't let your language studies fall behind. Once you get a good level of Japanese start looking for full-time employment. The outsourcing company will help with that if your work is good and have a good reputation with them and the companies you worked for. From A or other Recruit publications have Job listings that often pay better than those advertised on the Gaijin focused sites. But they also require a competency in Japanese. The Gaijinpot mentioned by http://Behati-Mateo, is a good source of information. Also contact the Japanese Embassy. They will be able to offer some advice but more about visas than work opportunities. Hope this helps.
