Since the rise of China, Japan declined a little bit and appearances at global events became scarcer.

As runner-up at the Fukuoka Universiade in 1995, Team Nippon (as the Japanese are also called) had a streak of success and qualified for the 1998 FIBA World Championship, its first qualification in over 30 years.
