Locate the province and the unlocking commander
To find a dungeon, first control/access its province, then meet its character or story prerequisite and use the relevant search command. Having a strong dungeon party does not make an absent discovery command appear. The table below selects ten useful classic-documented locations; it is not the full list of every dungeon.
Names follow the community reference and may differ from older fan translations or the Steam language you selected. Match province and unlocking character as well as the dungeon name.
Location and prerequisite table
| Dungeon | Province | Floors | Discovery gate | Distinct reward/check |
|---|---|---|---|---|
| Miso Katsu Dungeon | Owari | 6 | Kouhime | No additional named bonus beyond normal clear rules. |
| Heijo-kyo | Yamato | 6 | Kouhime | No additional named bonus listed. |
| Kachi-Kachi Cave | Kyo | 4 | Suzume | First clear gives 1 SAT; its separate side quest has additional requirements/rewards. |
| Pearl Dungeon | Ise | 7 | Kouhime | Sill is required for pearl bonuses; the Giant Pearl is a second-clear reward. |
| Tiger Pit | Himeji | 5 | Kanami | Three Kanou Scrolls on clear. |
| Study Pit | Texas | 8 | Sill | Sill’s healing improves by 5; no normal final drop is documented here. |
| Tanba Mine | Tamba | 9 | Maria | No additional named bonus listed. |
| Umeda Underground Mall | Naniwa | 8 | Katsuie Shibata | No fixed named bonus listed; do not infer a guaranteed item from a possible drop. |
| Sado Gold Mine | Sado | 10 | Kenshin and Ai Naoe | 5,000 gold on clear. |
| Tokugawa’s Buried Treasure | Mikawa | 13 | Ranmaru | Golden Ball requires Senhime; relevant to the NG+ dungeon completion mark. |
“No additional named bonus” does not mean no normal reward. It distinguishes the general first-clear behavior from a dungeon-specific item or event. Study Pit is an explicit exception to the normal final-drop expectation.
Why the discovery command is missing
Check the matching province, then the required character’s presence and the event state. For Sado Gold Mine, Kenshin alone is not the listed discovery gate: Ai Naoe is needed too. For Pearl Dungeon, finding it with Kouhime and receiving its special bonus with Sill are different checks.
If a required character is no longer available because of the route, do not assume that increasing Search will substitute for that character. The True Route guide identifies major story interruptions, and the foreign reinforcement page explains how to receive Kanami or Maria before planning their dungeon unlocks.
Normal first clears versus repeat visits
The community reference describes a first final-floor clear as granting a one-time level to current commanders and a normal treasure in most dungeons. Recruiting a character later does not retroactively give that character the old clear’s level reward. Plan useful clears around the roster you want to improve rather than assuming every replay produces another party-wide level.
Some final rewards are fixed when a campaign begins. Reloading the last fight may therefore repeat the same item. Named bonuses in the table have their own conditions: Pearl’s first and second results are different, and the Golden Ball is not guaranteed merely because the Tokugawa dungeon was discovered.
Use dungeon exploration and items for floor persistence and reward behavior. This location table does not promise exact drop rates or a best farming route.
Choose a clear for a reason
If the immediate need is a missing discovery command, solve the gate. If it is an army problem, check whether spending a map action on personal levels actually helps that battle. If it is a specific reward, verify its named condition before clearing the dungeon and moving on.
The main-story Underground Mikan Plantation and long route-specific dungeons are not interchangeable with this optional-clear table. For Hirami Lemons, follow the True Route mandatory objective; for the long Orochi challenge, use the Orochi unlock guide.
Prepare before entry
Personal HP, available moves and the ability to replace exhausted fighters matter underground. Leave enough army defenders available for the campaign after the crawl. When a retreat is needed, the game’s recorded floor persistence is not simply “every floor stays cleared forever.” See dungeon battle preparation before using a partial run to test a new dungeon.
