hololive Dreams Treasure Boxes Guide (トレジャーボックス)

Treasure Boxes (Japanese: トレジャーボックス) are collectible chests scattered across Dream Park in hololive Dreams (holodori). Community maps and Gamerch walkthroughs track roughly 42 chests split between Harmony Garden (Chapter 1 area) and the Megasphere (Chapter 2). Most appear after story episode clears or facility builds — not on day one. This guide lists known landmarks, unlock timing, troubleshooting tips, and how chest rewards fit your broader park loop.

Pair with the Dream Park overview, Facilities guide, Dream Park progression, and Chapter unlock roadmap so you know when each zone opens before hunting every box.

What Treasure Boxes give you

Opening a Treasure Box typically grants one or more of:

• Park materials for facility construction
• Cosmetics — outfits, accessories, or island decoration items
• Currency — coins, Diamonds in rare cases, or event tokens during limited campaigns
• Holomem-related items — customization parts or board materials on higher-tier chests

Chests are one-time per account. Once opened, the box disappears from the map permanently. Missing a chest during early exploration does not block story progress, but you leave free resources on the table — especially materials that gate Hoppin’ Rope or Megasphere repairs.

When chests appear

Treasure Boxes spawn in response to story progression, not real-time timers. General rules:

1. Clear the relevant story episode (EP) marker in Dream Park.
2. Complete linked facility builds when the quest demands them.
3. Return to the landmark area — the chest model appears near the named attraction.

Some Megasphere chests only appear during an active EP sequence (for example, mid-repair quests). If you advance story without backtracking, use the map list below on your next park visit.

Harmony Garden chest landmarks

Harmony Garden holds the majority of launch chests. Known community-documented locations (Gamerch / player maps, August 2, 2026):

Trigger	Location hint
After EP1	Near opening tutorial path — first island exploration reward
After Holo Home build (EP2)	Beside the Holo Home facility footprint
EP3	Dotabata Ground attraction area
EP4	Along main Harmony Garden route post-EP4 clear
EP7	Inside HOLO Cinemas — enter the building, check interior corners
EP8	Open-world Harmony Garden landmark after EP8
EP9	Central park path segment unlocked with EP9
EP10	Inside Tarafuku Journey — walk the ride interior
EP12	Behind Nepolabo Mart — circle the shop exterior
EP13	Behind Kiseki Wheel — approach from the rear path
EP14	Beside or behind Promise Tower — check both sides
EP16	Near Advent facility — generation-themed build zone
EP21	Atop Face Mountain — climb to the summit viewpoint

Harmony Garden chests often hide behind buildings or ride queue rails. If your map shows a cleared EP but no chest, walk a full 360° loop around the facility named in the table.

Megasphere chest landmarks

Megasphere chests unlock after Harmony Garden main story opens the second chapter zone. Documented spots:

Trigger	Location hint
On arrival / early lobby	Lobby left, lobby entrance, and play area left wall — three early boxes visible once Megasphere loads
After EP3	Lobby area refresh — new chest positions post-episode
During EP5 repairs	Appear while fixing Broken Crane, Onigiri Panic, Dance Dance Phoenix, and Shibakiage Fighting attractions
After EP6	Following MegaPri repair completion
After EP8	Post-casino switch story beat — casino zone access changes layout
After EP9	Following High&Low and Lottery Chama Max unlocks

Megasphere interiors use multi-floor layouts. If a chest should exist per your EP progress but you cannot see it, check alternate floors and casino side rooms unlocked in EP8–EP9.

Interaction and troubleshooting tips

Community reports from launch week highlight recurring issues:

• Approach from the front if the interact prompt fails — chests clipped into scenery sometimes register only from one facing angle.
• Restart the client if the Open button never appears despite standing on the glow — a soft relaunch fixes desynced interactables on iOS, Android, and Steam.
• Some chests require prior boxes — a few Megasphere chains gate later spawns behind earlier EP clears or solo exploration flags.
• Solo explore first — finish the EP cutscene, then free-roam before returning to rhythm Lives; chests tied to facility build completion appear only after the construction animation finishes.

If a chest still will not open after restart, verify your chapter progress on the Chapter unlock guide — you may be one EP short of the spawn condition.

Recommended collection route

Efficient sweep for new accounts (August 2026 context):

1. Push Harmony Garden main story through EP10 while opening every chest in the table above.
2. Unlock Holomem Board (Chapter 2 menu path) per Chapter unlock — not required for chests, but aligns with facility pacing.
3. Complete Harmony Garden arc → enter Megasphere → grab lobby trio immediately.
4. Continue Megasphere EPs 5 → 6 → 8 → 9, backtracking for repair-phase chests before starting the next EP.
5. Cross-check Holomem Quests NPC markers — quest destinations often sit beside unopened boxes.

Add a five-minute chest scan to your Daily checklist until Harmony Garden is 100% cleared.
