The displayed coordinates are near the front of Daisen Kofun
(Nintoku-ryo Tumulus). There is a model of Daisen Kofun and its
accompanying small tumuli, however, the physical cache is not
there. You need to solve a puzzle to get the final coordinates.
Mozu Kofun Group is a group of Japanese old tumuli (kofun) located
in Sakai City. Several large tumuli includes Daisen Kofun are
belong to this group, and totally about 50 tumuli are remains,
though the same number of tumuli were destroyed in the city
development.
Kofun are graves of powerful families’ persons in Japan. You
may notice the feature of the shape of tumulus like a keyhole. This
type of tumuli are indigenous to Japan and most of large scale
tumuli are this type. The round part of a tumulus is the main part
where a dead person is buried. The trapezoidal or rectangle part is
thought that its origin is an alter or a road access to the grave.
Several variations of the rectangle parts are known (ex.
1,
ex. 2). Tumuli which have very small rectangle parts are called
“scallop-shell shaped kofun”.
The cache is hidden near a keyhole shaped kofun belongs to Mozu
Kofun Group. The coordinates (like DD MM.MMM) are encrypted into
the figure below.

表示されている座標は大仙古墳（仁徳陵）の正面付近です。この場所には大仙古墳の模型が展示されていますが、キャッシュは別の場所にあります。暗号を解いてキャッシュの座標を導出してください。
百舌鳥古墳群は大阪府堺市にある古墳群です。大仙古墳をはじめ、複数の大規模古墳を擁し、都市開発で半分ほどが消滅したものの、現在も50ほどの古墳が現存しています。
日本の古墳で大型のものは、前方後円墳という特徴的な形をしています。後円部が墓の本体、前方部は祭壇か墓道が変化したものだろうと考えられています。前方部は、よく見られる台形のほかに、撥形のものや、台形の底辺が外側に膨らんでいる剣菱型のものもあります。また前方部が極端に小さいものは「帆立貝形古墳」と呼ばれます。
キャッシュは百舌鳥古墳群に属する前方後円墳の近くに隠されています。座標を得るには、下に示した暗号を解読してください。
