This is interesting , from article : " The Japanese Navy was still inspired by Germany's large Zeppelins. Dr. Hugo Eckener's successes. The trek from Frederickshafen to Tokyo of the "Graf Zeppelin" rekindled the country's enthusiasm. Japanese Naval officers visited the construction of Akron and Macon in America and viewed the construction of the Hindenburg Zeppelin. A German Air Ministry staff member went to Japan to discuss building airships for Japan.
In 1936, the Japanese Navy secretly backed the idea of the "Eastern Hemisphere Airways, Ltd". The company began soliciting funds and selling stock to obtain two Zeppelins to operate a trans-Pacific route to San Francisco from Tokyo. Without official government backing, the project failed. This was the final Japanese attempt.
In May 1937, the Hindenberg flight to Lakehurst, New Jersey ended the world's interest in LTA ".
