Isamu-Jima

A folio of the realm

Isamu-Jima

Isamu-Jima is the largest island in the Tokuno Islands group, introduced with the Samurai Empire expansion (2004). The island is dominated by the stratovolcano Mount Sho and contains a wide variety of biomes — from the icy Winter Spur in the north to the Lotus Lakes in the southeast and the Tsuki Forest woodland environs. Isamu-Jima hosts two of the most distinctive Tokuno landmarks: the Fan Dancer Dojo (a special ninjitsu-themed quest dungeon) and the Valley of the Sleeping Dragons (a peaceable dragon-eyrie). The island also serves as the mainland entrance to The CitadelTravesty's Court — at its eastern flank.

Geography (16-region map)

1. Beetlescape

A place to hunt the Rune Beetle without a Yamandon present — Beetlescape is the safer Rune Beetle hunting ground for tamers seeking the rare insect mount.

Spawn
Crane Evil Mage
Evil Mage Lord Kappa
Rune Beetle

2. Winter Spur

The icy environment in the north hosts chilly villains.

Spawn
Giant Ice Serpent Ice Elemental
Lady of the Snow Polar Bear
Snow Elemental Snow Leopard
Walrus

The Lady of the Snow is a notable Tokuno-myth boss — a yuki-onna inspired creature with cold-themed abilities.

3. Fan Dancer Dojo Entrance

See main article: Fan Dancer Dojo. A ninjitsu/bushido themed quest dungeon.

4. Valley of the Sleeping Dragons

See main article: Valley of the Sleeping Dragons. A peaceable eyrie of slumbering dragons; sometimes hostile when disturbed by event-cycle quests.

5. Lightest Dark

The name implies the resident — the Rai-Ju is the thunderous companion to the Shinto god of lightning. Lightest Dark hosts these mythological lightning-creatures.

6. Hiryu Forest

Spawn
Elite Ninja Hiryu
Kaze Kemono Lesser Hiryu

The Hiryu here is a notable tame target — the full-grown Hiryu mount is one of the most prized rideable pets in UO.

7. Yamandon Point

If it is Rune Beetles you seek, try Beetlescape (Region 1) instead — Yamandon Point has Rune Beetles plus the Yamandon, which is far more dangerous.

Spawn
Deathwatch Beetle Rune Beetle
Yamandon

8. Tsuki Forest

Forest environs yield forest creatures, truism for Butcher's War Cleaver.

The Tsuki Forest is a forest woodland — ideal hunting ground for an archer or ranger character pursuing the Butcher's War Cleaver quest reward (a butcher-leather farming utility).

Spawn
Black Bear Brown Bear
Dire Wolf Grey Wolf
Reaper Rideable Llama
Timber Wolf Tsuki Wolf

9. Lotus Lakes

Spawn
Crane Dread Spider
Giant Black Widow Giant Spider
Kappa

A spider-rich environment in the southeast. Useful for tamers seeking poison-resistant pets to fight here, or anyone using Arachnid Slayer weapons.

10. Mount Sho

The eastern slope contains undead, while the volcano proper has fire-based creatures.

Spawn (East slope) Spawn (Volcano)
Bone Knight Fire Elemental
Bone Magi Hell Hound
Hellcat (Large) Lava Lizard
Revenant Lion Lava Serpent
Rotting Corpse
Skeletal Knight
Skeletal Mage

11. Lake Kappa

Cranes, Deathwatch Beetles, and Kappas. A more pastoral setting; useful for low-tier farming.

12. Hotaka Plains

Healers can usually be found around the pavilions to the north and northeast of this open area — making Hotaka Plains a useful safe-rest stop for adventurers traversing the island.

Spawn
Elite Ninja Gaman
Hiryu Lesser Hiryu
Oni

13. The Citadel Entrance

See main article: The Citadel. The eastern entrance to Travesty's Court — the Mondain's Legacy Peerless dungeon.

14. Isamu-Jima Moongate

Coordinates 55° 1' N, 10° 49' W

The primary moongate access to Isamu-Jima.

15. Storm Point

The sea has seemingly flung her dead upon Storm Point — undead and shipwrecks are present.

Spawn
Bone Magi Crane
Deathwatch Beetle Kappa
Revenant Lion Skeletal Mage

16. Mount Hakonu

A small volcanic island off the eastern coast.

Spawn
Fire Elemental Hell Hound
Kappa Lava Lizard
Lava Serpent

Strategic and lore notes

  • Largest Tokuno island = most diverse spawn ladder; an Isamu-Jima character can train across many monster types.
  • Rune Beetle is the canonical farm-able rare-pet target — Beetlescape (safer) or Yamandon Point (with risk).
  • Hiryu Forest + Hotaka Plains + Hiryu Forest form a Hiryu-tamer corridor — the rideable Hiryu is a prestige mount.
  • The Citadel entrance is on the eastern flank — Mondain's Legacy era's Tokuno Peerless dungeon.
  • Mount Sho offers fire-themed combat with adjacent undead — diverse damage/resist types in a small zone.
  • Hotaka Plains' healers are a strategic rest point for cross-island treks.
