Bell imported telephones were tried immediately in the Ministry of Industry, while imitations were modeled on this telephone in the machine-building division of the Telegraph Office. The first two telephones were completed in June of the eleventh year of the Meiji Period (1878). After the Seinan War, the number of telegrams, which amounted to between 400,000 to 500,000 annualy before the war, increased in excess of 900,000 through 1.5 million. In 1889 when the Constitution of the Japanese Empire was promulgated, a newspaper company sent the full text of the Constitution from Tokyo to Osaka and issued an extra edition on the same day. The telephone appeared also in 'Five hundred selected compositions by elementary schoolchildren' and in the second Industrial Exposition, a carbon telephone was displayed. Interest in the telephone and telegraph was on the rise.
