Source-derived summary

The London Protocol was concluded on 6 June 1862 between Japan and the United Kingdom at the conclusion of the First Japanese Embassy to Europe. It was signed on the British side by Foreign Secretary John Russell, 1st Earl Russell.

Under the protocol, the United Kingdom ceded some of its rights under the Anglo-Japanese Treaty of Amity and Commerce for a period of five years beginning 1 January 1863. In exchange, the Japanese government reiterated its responsibilities under that treaty to fully open the ports of Nagasaki, Hakodate and Kanagawa to foreign trade.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as signed between Japan and United Kingdom. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 15, 2026. The linked authority identifier is Q11350850. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1862 and 1863.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
