On Feb. 15 the Japan Olympic Committee announced that Rikuren has nominated men's marathon national record holder Toshinari Takaoka, 39, to a special position researching overseas training methods. Takaoka, who retired last March and is now a coach with Team Kanebo, must undergo a round of interviews with the JOC before being named to the position. According to a person involved in the proceedings, if Takaoka is accepted he will be sent to the United States to study American altitude training and coaching methods.

I think the interview with Takaoka that I put up today suggests answers to your questions.

Many traditional Japanese arts are taught through observation of the master rather than direct instruction by the master. No need for anyone to spill their beans for Takaoka to learn from them.
