About MOSA (English)

MOSA Nonprofit Corporation

The MOSA Software Meeting

The MOSA Software Meeting is an annual 2 days technical seminar held in the Tokyo metropolitan area. Each year about one hundred Japanese developers gather to sharpen their skills. Apple Japan supports the annual MOSA Software Meeting, often providing guest speakers and other resources.


The annual WWDC briefing

Because not all Japanese developers are able to travel to the United States to attend Apple’s World Wide Developers Conference(WWDC), each year MOSA provides a briefing in Tokyo following the conference. The briefing, conducted by senior members of MOSA who attended the conference, summarizes the most relevant information for Japanese developers. The annual WWDC briefing is co-sponsored by Apple Japan. MOSA also holds a similar briefing in January following Macworld EXPO in San Francisco.


MOSA corporate member-only meetings

MOSA corporate members are eligible to attend member-only meetings to exchange information and study specific topics. One such event last year was attended by representatives of Apple’s World Wide Developer Relation staff from the United States. During the event Japanese developers were able to give their feedback directly to Apple.

MOSA holds social events during year, including a member’s cafe´ and a New Year’s party.



Seminars are held several times a year on key technologies of interest to those doing professional development. Recent topics have included WebObjects, Cocoa, and Driver development. Seminars for beginners are given to promote interest in Macintosh programming in the next generation of developers.
