On 22 May 1922 (!) received the Dutch naval staff at The Hague, Netherlands from the Dutch embassy at Tokyo, Japan a detailed specification of Japanese merchant ships of minimum 1.500 tons tonnage usable for troop transport over sea in October 1921. If the transport was over a short distance for instance Japan-Philippines or Japan-Chinese harbour was the transport capacity increased with 10% and on a distance within 24 hours even doubled. The figures were supplied by non-Japanese experts, partly based on the troop transports between Japan-China and Japan-Siberia. The transports were kept secret. At that moment was Japan already considered as a potential enemy. For each ship was mentioned how many troops included equipment could be transported over a longer distance, for instance to an island belonging to the Dutch East Indies. In February-March 1942 invaded Japan indeed the Dutch East Indies.
