"German warships and armed vessels," said the foreign minister, "are prowling around the seas of eastern Asia, menacing our commerce and that of our ally, while Kiao-chau was carrying out operations apparently for the purpose of constituting a base for warlike operations in eastern Asia. Grave anxiety was thus felt for the maintenance of peace in the Far East.
"As all are aware," he continued, "the agreement and alliance between Japan and Great Britain has for its object the consolidation and maintenance of general peace in eastern Asia, and the maintenance of the independence and integrity of China, as well as the principle of equal opportunities for commerce and industry for all nations in that country, and the maintenance and defense respectively of territorial rights and special interests of contracting parties in eastern Asia. Therefore, inasmuch as we are asked by our ally for assistance at a time when commerce in eastern Asia, which Japan and Great Britain regard alike as one of their special interests, is subjected to a constant menace, Japan, who regards that alliance as a guiding principle of her foreign policy, could not but comply to the respect to do her part."
The Japanese statesman offered this explanation to his people: "Germany's possession of a base for powerful activities in one corner of the Far East was not only a serious obstacle to the maintenance of a permanent peace, but also threatened the immediate interests of the Japanese Empire. The Japanese Government, therefore, resolved to comply with the British request, and, if necessary, to open hostilities against Germany."
Baron Kato's speech was delivered after Japan had declared war. The Western world, when it found time to turn its attention from the absorbing drama already being enacted in Belgium to the minor crisis in the Far East, was not left long in doubt regarding the intentions of Great Britain's ally. War was declared on August 24, 1914, nine days after Japan had dispatched to Germany an ultimatum, which Germany scornfully ignored.
The text of the ultimatum was as follows: "We consider it highly important and necessary in the present situation to take measures to remove the causes of all disturbance of peace in the Far East, and to safeguard general interests as contemplated in the agreement of alliance between Japan and Great Britain.
"In order to secure firm and enduring peace in eastern Asia, the establishment of which is the aim of the agreement, the Japanese Government sincerely believes it to be its duty to give advice to the German Government to carry out the following two propositions:
"(1) To withdraw immediately from Japanese and Chinese waters the German warships and armed vessels of all kinds, and to disarm those which cannot be withdrawn.
"(2) To deliver on a date not later than September 15 to the Japanese authorities, without condition or compensation, the entire leased territory of Kiao-chau, with a view to the eventual restoration of the same to China.
"The Japanese Government announces at the same time that in the event of its not receiving by noon on August 23, 1914, an answer from the German Government signifying unconditional acceptance of the above advice offered by the Japanese Government, Japan will be compelled to take such action as it may deem necessary to meet the situation."
