The Onsen Egg Promise is a 16-day Winter Frost quest where you photograph one cracked egg per day across Onsen Mountain and Winter Utopia. Complete all 16 to permanently unlock the Onsen Egg cooking recipe — one of the best gold-per-minute methods in the game.
Event route bridge
Onsen Egg searches still bring players into the site, but the active session now needs a bridge into Modular Streets, cooking, and daily reset planning. Use this quick board before following older screenshots.
Open the event panel first. If Modular Streets dailies are active in the same session, finish the time-boxed token or location task before wandering through old egg spots.
Treat Onsen Mountain as a compact hub: confirm the egg tracker, cook any saved eggs, then route into nearby fishing or recipe errands.
Older Onsen Egg screenshots are still useful for landmarks, but the in-game panel and current day order should decide the final target.
If today sends you toward the beach north of Onsen, combine the Onsen landmark pass with Brick Birdwatching, gathering, and any bouquet-style objective shown in your panel.
Recipe clarification
The Onsen Egg route is still worth keeping because players use it for recipe unlocks, bubble troubleshooting, and cooking-profit planning. The important update is intent separation: active-event players should start from the live panel, while recipe-unlock players can use this archive.
Players are still searching for egg and recipe confusion while Modular Streets is active. Treat this page as the archive for the 16-photo route and the cooking unlock, not as today's active daily event panel.
Community questions this week confuse the old Onsen Egg recipe with normal egg or Easter-event recipes. If a player asks where the egg recipe is, check which recipe name the in-game panel shows before sending them to Winter Utopia screenshots.
Winter Utopia landmarks, Blanc, Massimo, Vanya, the rink, and boardwalk rocks remain useful for screenshots, but current active objectives should come from the live event panel.
If the player already unlocked Onsen Egg cooking, cook saved eggs after Modular Streets collection tasks so profitable cooking does not cause missed limited fish, birds, or store riddles.
The Onsen Egg Promise is a seasonal quest tied to the Winter Frost and Winter Utopia event area. Each event day, a cracked egg appears somewhere around the ice rink, igloo buildings, pop-up stalls, boardwalk, or nearby Onsen Mountain landmarks. Your task is to find it and take a photograph using your camera tool.
Unlike normal map collectibles, these eggs unlock sequentially. You must register the current egg before later entries matter. After photographing all 16 eggs, the event unlocks the Onsen Egg Recipe. If your event version also spawns a furniture bubble or decoration reward, collect it before reset instead of assuming it will remain available later.

Eggs appear one per day in sequential order. Each egg is a cracked, glowing object — look near landmarks and structures. Use your camera to photograph it once found, then confirm the event panel before leaving the area.
| Day | Area | Egg Location | Photo Check |
|---|---|---|---|
| 1 | Winter Utopia entrance | Behind the Naughty NPC, on or beside the welcome-sign fence post. | Start the quest here before looking for later eggs. |
| 2 | Ice rink | On the deer or moose snow statue near the ice-skating rink steps. | White eggs blend into snow, so rotate the camera above the statue. |
| 3 | Igloo stairs | Under the wooden stairs leading toward the snowman or igloo building. | Look from ground level; the stair shadow hides the green egg. |
| 4 | Blanc flower stall | Behind Blanc's flower or gardening stall near rocks and flower pots. | Walk around the stall instead of only checking the front counter. |
| 5 | Massimo cooking stall | On the roof or top ledge of Massimo's pop-up cooking station. | Use the nearby steps and look across the stall roofline. |
| 6 | Snowman dome | On the snowman dome or igloo-top edge near the skating-rink building. | Scan high surfaces after climbing the central steps. |
| 7 | Main igloo interior | Inside the main Winter Utopia building, on the penguin-style table. | Enter the building; this egg is easy to miss if you only sweep outdoors. |
| 8 | Coffee stand | On the coffee stand or umbrella table to the right of the main building. | Circle the stand and tilt the camera upward. |
| 9 | Wooden deck route | On a rock near the wooden bridge or boardwalk route to the right of the main building. | Check both the rock face and the space below the deck. |
| 10 | Blanc stall shelf | On the right side of Blanc's stall, close to the blue flowers or display shelf. | This is a front-of-stall find; do not over-search the mountain trail. |
| 11 | Palm or Annie tree cluster | Between frosty palm trees near Azure, or on the nearby tree branch reported beside Annie. | Public reports vary by wording, so sweep both the palm trunks and the adjacent branch. |
| 12 | Azure rock and plant patch | Beside the rock and red-petal plant cluster near Azure or the nearby bushes. | Walk the plant line slowly; foliage can cover the egg from one angle. |
| 13 | Vanya fishing stall | On top of Vanya's fishing stall in the Winter Utopia area. | Look above the stall roof rather than under the counter. |
| 14 | Massimo rooftop | On Massimo's pop-up cooking roof near the ice-rink steps. | Do not confuse it with the earlier lavender egg location on the opposite side. |
| 15 | Ice rink table or bench | Inside or beside the ice rink, on the top-right bench or snow-cone table area. | Stand at rink level and check the upper-right corner before leaving. |
| 16 | Seaside boardwalk rocks | Near the wooden decking and seaside-boardwalk rocks, close to the earlier orange egg route. | Face Azure, turn toward the wooden deck, then scan the rocks beside the path. |
Verification note: this table was refreshed on May 24, 2026 against public community route reports and the known Winter Utopia landmark names. Some fan guides describe the same spot with different NPC or area labels, so the photo-check column names the visual cue to confirm in game.
These short answers are written for players and AI search systems that need a direct, source-like summary before the full route table. Use them to confirm the quest start, failed-photo fixes, and final recipe reward.
The first Onsen Egg starts at the Winter Utopia entrance, behind or beside the Naughty NPC near the welcome sign fence post. Talk to Naughty first, then photograph the cracked egg before searching later days.
The most common reasons are wrong day order, quest not started with Naughty, the egg not centered in photo mode, or leaving before the event panel confirms progress. Move closer and retake the picture until the panel updates.
Photographing all 16 Onsen Eggs unlocks the Onsen Egg cooking recipe permanently. After that, players can cook eggs in the Onsen Mountain boiling baskets and sell high-quality eggs for strong early-game gold.
Use this route when you only have a few minutes to clear the daily egg. It keeps the search focused on the two event regions and prevents the most common mistake: taking the photo but forgetting to confirm the reward state before leaving.
Step 1
Check your current egg day, empty one inventory slot, and equip the camera tool.
Step 2
Start at the mountain bus stop, check the hot spring pools, cooking baskets, bamboo grove, shrine path, and peak platform.
Step 3
If the day points to Winter Utopia, scan the rink, lodge entrance, frozen waterfall, ski cabin, plaza tree, and lake edge.
Step 4
Open the event panel and confirm the egg counted. If the event version spawns a reward bubble, collect it before the daily reset.
Step 5
Visit the boiling baskets near the Onsen Mountain hot springs and batch-cook raw eggs for the best gold return.
After unlocking the recipe, head to the boiling baskets on Onsen Mountain (near the bus stop area). These special baskets only cook Onsen Eggs — they cannot be used for other recipes.
Pro tip: Use all available baskets at once. Since eggs cannot burn, you can start multiple batches and complete side tasks while they cook. This maximizes your gold per trip.
Confirm you started the quest with Naughty, check the correct day number, and rotate the camera because several eggs sit on high surfaces or under stairs.
Move closer until the egg name appears, center the egg in photo mode, and retake the shot before closing the event panel.
Open the event panel first. Some event versions spawn a separate reward bubble after the photo; others only mark progress in the panel.
Continue from the earliest unlocked egg. Do not assume the decoration reward can be recovered after reset unless the current in-game panel confirms it.
| Quality | Sell Price | Notes |
|---|---|---|
| ★☆☆ | 90 gold | Base quality, no bonuses |
| ★★☆ | 170 gold | Requires cooking skill level 3+ |
| ★★★ | 260 gold | Max quality — best profit per egg |
Here is a day-by-day strategy to complete the quest efficiently while maximizing gold from cooking.
Log in daily and head to the egg location listed above. Each photo takes under 2 minutes. Buy 10 raw eggs from Massimo on Day 1 to have stock ready once you unlock the recipe.
Continue daily photos. Buy another 20 raw eggs from Massimo. You now have 30 eggs ready for batch cooking. Focus on upgrading your cooking skill to level 3+ for 2-star and 3-star output.
Keep photographing. If you have cooking skill 3+, start practicing other recipes to improve quality odds. Buy another 20 raw eggs (total stock: 50).
Photograph the final egg at the shrine platform. The Onsen Egg Recipe unlocks immediately. Head to the boiling baskets and cook all 50 eggs. At 3-star quality, that is 50 × 260 = 13,000 gold in one session.
During the Winter Frost or Winter Utopia event window, start near the Naughty NPC at the Winter Utopia entrance. The first cracked egg is behind the NPC near the welcome sign or fence post, and later eggs unlock sequentially after the current photo registers.
Yes. Only one new egg is relevant to your current event day, unlocking sequentially from Day 1 through Day 16. You should confirm the current egg in the event panel before trying later community-reported locations.
Completing all 16 photographs unlocks the Onsen Egg Recipe permanently. You can then cook Onsen Eggs anytime using the boiling baskets on Onsen Mountain.
Check the event panel immediately after each photo. If the current event version spawns a reward bubble or decoration pickup, collect it before leaving because some rewards can disappear after the daily reset.
Purchase raw eggs from NPC Massimo in the market area. Each egg costs a small amount of gold. Stock up before heading to the hot springs to cook in bulk.
No. Unlike regular cooking, Onsen Eggs cooked in hot spring baskets cannot burn. You can safely use multiple baskets simultaneously for batch cooking.
Three-star Onsen Eggs sell for approximately 260 gold each. With batch cooking across multiple baskets, this becomes one of the most efficient gold-per-minute recipes in the game.
Yes. Once you unlock the recipe by photographing all 16 eggs, you keep it permanently. The boiling baskets on Onsen Mountain remain available year-round.
