In the early 20th century, studying abroad was no simple matter. The high cost was one thing, but the most critical barrier was the language.
The prerequisite for studying abroad was to first learn a foreign language, not only to satisfy conversational needs but also to reach examination standards.
Apart from the third-rate universities in Japan that were open to all comers, other universities had their thresholds. Unless one could pay a hefty sponsorship fee, the only other option was to pass an entrance examination.
Whether the selection process was by written test, interview, or recommendation for admission, there was no uniform standard.
Whether one could stand out was not only a matter of individual ability but also, more importantly, a matter of networking.
