英日国家关系是近代东亚国际格局中的重要一环。甲午战争后，日本和英国对于俄国的扩张心存芥蒂，共同利益驱使着两国组成同盟，抗击俄国的东进。尽管过程略有曲折，但两国还是成功建立了第一次英日同盟。日俄战争期间，英国和日本在各自的立场上向对方提供支持，维持着英日同盟的存续。英国在军事、技术、经济方面给予了日本莫大的善意，日本也尽心尽力遏制着国内不良舆论的传播。这些标志着日英关系的不断攀升，但矛盾却也悄然滋生。等到双方签订第二次英日同盟，矛盾的激化越来越严重，使得两国在维持同盟的同时也开始寻求新的外交策略和伙伴，意味着英日关系依旧友善但升温速度有所放缓。

The diplomatic ties between Japan and England constitute a pivotal aspect within the modern East Asian geopolitical landscape. In the aftermath of the First Sino-Japanese War, a period ensued during which Japan and England, harboring mutual apprehension toward Russian expansionism, were impelled by shared interests to forge an alliance, countering Russia's eastern advances. Despite some vicissitudes along the way, the two nations successfully established the inaugural Anglo-Japanese Alliance. Throughout the Russo-Japanese War, England and Japan extended reciprocal support from their respective positions, upholding the continuity of the Anglo-Japanese alliance. Particularly noteworthy was England's considerable benevolence toward Japan. These events marked Japan-England relations, yet simmering contradictions quietly burgeoned. As the Second Anglo-Japanese Alliance was ratified, these contradictions intensified, prompting both nations to seek new strategies and allies, signaling the decline in Japan-England relations.
