Overview
Geographical/topographical features
The Recreation Forest is located in a hilly area of Ariake Mountains in the southern part of the island of Tsushima. Small peaks form a row with Mt. Ariake at the center, and the topography is relatively steep except for the summit part. Mt. Ariake is the largest mountain you can see in front of you when you are bound for Izuhara Port by ferry. The summit part is a flat grassland where you can relax and eat lunch or take a break. It overlooks the ruins of the Shimizuyama Castle and the town of Izuhara, and the summit commands a view of Mt. Yatate (648 m), Mt. Shiratake (515 m), and the scenic Aso Bay with the complicated coastline of the ria coast.
Historical/cultural features
Poem No. 3,516 in Manyoshu (Collection of Ten Thousand Leaves) Vol. 14 is a poem read by a Sakimori guard (Sakimori guards are soldiers who were gathered from distant areas to guard northern Kyushu (Tsushima, Iki, and Fukushima) after the Battle of Baekgang with the Korean Peninsula in 633), which says as follows: the peak in Tsushima is low, so there are no clouds under it; so I will look at the clouds trailing over a god-dwelling peak and think of you. This poem describes the scene where Sakimori guards who have left their hometown think about their families and loved ones they have left behind. The "peak in Tsushima" read in the poem is not necessarily Mt. Ariake, but as it is the mountain that looks the largest when seen from the Izuhara Port, it can well be referring to Mt. Ariake.
Since those times, Tsushima had had important relationships with neighboring countries as a "border island" at the forefront of the battle lines, but after diplomatic relations were restored, it served as an island of friendship.
The Recreation Forest overlooks the ruins of the Shimizuyama Castle, which is said to have been built by Toyotomi Hideyoshi when dispatching troops to Korea in 1591. It was a nationally unique mountain castle structured in steps, and its ruins have been designated a national monument. Many remains that remind us of old-day Tsushima are found in the vicinity, including Bansho-in Temple―the family temple of the So Clan, the Shugodai (deputy military governor) of the Tsushima Domain, with a 100,000 koku stipend―which is counted as one of Japan's three largest cemeteries along with the Maeda Clan Cemetery in Ishikawa Prefecture and the Mori Clan Cemetery in Yamaguchi Prefecture. The turbulent border island Tsushima, which has changed over time, draws attention as a historically and culturally valuable place.
Climate, flora and fauna
From late March to April, on sunny ridges and near the summit, Genkaitsutsuji (Rhododendron mucronulatum ciliatum (Rhododendron mucronulatum Turcz. var. ciliatum Nakai)) gives bloom to a couple of vivid rose-pink flowers at the tip of each branch before the leaves come out, and add breath-taking colors to the lonely scenery that has withered in winter. Around that time, pretty flowers such as Fuderindo (Gentiana zollingeri Fawc.) and Shihaisumire (Viola violacea Makino var. violacea) bloom near the ground, and herald the spring in Tsushima. During the early-summer rainy season, the white flowers of Yamaboshi (Japanese dogwood (Cornus kousa Buerger ex Hance subsp. kousa)) are at their best.
The mountain trail runs through a planted forest of Hinoki (Japanese cypress (Chamaecyparis obtuse)) at some places, but a laurel forest consisting of Sudajii (Castanopsis sieboldii (Makino) Hatus. ex T.Yamaz. et Mashiba), Yabutsubaki (Japanese camellia (Camellia japonica)), and Akagashi (Japanese evergreen oak (Quercus acuta)) also remains, and Aridoshi (Damnacanthus indicus Gaertn. f.) can be frequently seen on the forest floor. The planted Japanese cypress has a distinctively characteristic color and scent and is sold under a brand called "Taishu Hinoki."
Attractions
The trailhead is at a walking distance from the central part of the Izuhara Town where the Izuhara Port and restaurants are concentrated. Mt. Ariake is easy to hike even for beginners, as it only takes about two hours to the summit and the trail has few hazardous spots.
The summit area is an open grassland where hikers can eat their lunch in a pleasant breeze in spring and autumn, and if the weather conditions are good, they can view the silhouettes of the Korean Peninsula and the island of Iki.
As one of the routes goes through the ruins of Shimizuyama Castle, which Toyotomi Hideyoshi built when dispatching troops to Korea, hikers can feel the nature and the history of the border island Tsushima as they hike. Why don't you enjoy trekking while thinking about people in the long history of Mt. Ariake, which lies unchanged since the times far beyond the Sengoku period (the period of warring states) ?
