Source-derived summary

Suijutsu (水術) or suieijutsu (水泳術) is the Japanese martial art of combative swimming. The Literal translation of the term from Japanese is "water skills". It is sometimes called Nihon eiho.

Various styles existed, which were codified into different ryūha. The Iwakura ryū specialised in techniques for dealing with unusual situations such as consuming meals while in the water. The Shinden ryū taught methods for long-distance swimming, while the Kankai ryū focused on swimming in the ocean. Many schools taught methods of swimming in armour (katchu gozen oyogi). Suijutsu was considered to be one of the bugei jūhappan, the eighteen fundamental martial techniques.

Editorial summary

This brief starts where responsible research should: with the source description of “Suijutsu” as japanese ancient swimming style. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 145-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Suijutsu, Japanese and ancient can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as japanese ancient swimming style. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q1683358. None of the 0 selected statements returned an explicit reference.

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

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
