占領地切手 11 （ジャワ1） 1943（昭和18）－1944（昭和19）発行
1942年（昭和17）3月、ジャワ作戦終了後、日本軍は現地切手を一部を除き従前使用させた。また、日本切手を持ち込み、日本や他の占領地との通信用に加刷無しで使用させた。その後、 1943年（昭和18）3月、占領1周年切手や正刷普通切手、貯金切手を発行した。正刷切手は、他の占領地と同じく、日本の内閣印刷局が製造し発行した。それらの切手は、1945年8月の戦争終了と共に、その効力を失った。 ＊今井修著『日本切手100年小史』日本郵趣出版1978年P168-169参考
Occupation stamps 11 (Java 1) Issued from 1943-1945
In March 1942 (Showa 17), after the end of Operation Java, the Japanese army used the local stamps except for some. He also brought in Japanese stamps and used them for communication with Japan and other occupied territories without overprinting. After that, in March 1943 (Showa 18), stamps for the 1st anniversary of the occupation, definitive stamps, and savings stamps were issued. Regular stamps, like other occupied territories, were manufactured and issued by the Japanese Cabinet Printing Bureau.
Those stamps became ineffective at the end of the war in August 1945. * Osamu Imai, "100 Years of Japanese Stamps", Nihon Yushu Shuppan, 1978, P168-169 Reference
