Final answer:
The deeply-rooted bureaucratic structure and the complex Japanese language were the greatest hindrances to the development of software innovations appropriate for world markets in Japan.
Step-by-step explanation:
The greatest hindrance to the development of software innovations appropriate for world markets in Japan was the deeply-rooted bureaucratic structure. The bureaucracy in Japan had a strict hierarchy and decision-making process, which made it difficult for software innovations to be implemented quickly and efficiently. This hindered the development of software that could cater to the specific needs of global markets. Additionally, the complex Japanese language also posed a challenge as keyboards and cell phone screens were better suited for alphabet-based systems, rather than the logogram-based Japanese language.
