List of extreme points of Japan
Wikimedia list article

The extreme points of Japan include the coordinates that are the farthest north, south, east and west in Japan, and the ones that are at the highest and the lowest elevations in the country. Japan's northernmost point is disputed, because Japan considers it to be on Iturup, an island de facto governed by Russia. The southernmost point is Okinotorishima; the westernmost is Tuishi near Yonaguni Island in Okinawa Prefecture, and the easternmost is Minami Torishima. The highest point in Japan is the summit of Mount Fuji at 3,776.24 m (12,389 ft). At 150 m (492 ft) below sea level, the bottom of Hachinohe mine is the country's lowest point. The surface of Hachirōgata is Japan's lowest natural point at 4 m (13 ft) below sea level. All extreme locations are uninhabited.
Japan extends from 20° to 45° north latitude (Okinotorishima to Benten-jima) and from 122° to 153° east longitude (Yonaguni to Minami Torishima). The coordinates used in this article are sourced from Google Earth, which makes use of the World Geodetic System (WGS) 84.

This brief starts where responsible research should: with the source description of “List of extreme points of Japan” as wikimedia list article. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as wikimedia list article. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 Feb 24, 2026. The linked authority identifier is Q1059347. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
