Tsurumi Island: Day 1 Mistakes & The Puzzle That Almost Broke Me (A Q&A Guide)

Everything I Wish I Knew Before Setting Foot on Tsurumi Island

Look, I'm the guy who spent three hours running in circles on Day 1 of Tsurumi Island. Three hours. I felt like an idiot. But I documented my failures (because of course I did) so you don't have to repeat them. This guide answers the questions I had before I started, and a few I wish I'd asked.

Honestly, I'm not sure why the game designers made the fog mechanic so punishing. My best guess is they wanted us to feel lost. They succeeded. (This was back in October 2021, by the way—things may have been patched since.)

Question 1: How do I even start the Tsurumi Island quest?

From the outside, it looks like you just need to sail to the island. The reality is you need to trigger the world quest "Tsurumi Island" by talking to an NPC named Kama on the docks of Ritou. No chat bubble, no exclamation mark—at least, that's been my experience. You have to walk right up to him and initiate conversation. I missed him for an entire day (ugh).

After you talk to Kama, you'll get the quest "The Peculiar Wonderland." That's your starting point. Follow it religiously until you can clear the fog from the island's initial area.

Question 2: Why can't I see anything? The fog is unbearable.

The fog is a puzzle, not a graphics glitch. (Surprise, surprise.) You need to use a gadget called the "Warding Stone" to clear it. The game gives you this after a few steps into the quest. You can't brute-force your way through it. Simple.

Here's the thing: most players assume the fog is a temporary weather effect that will clear on its own. It won't. You have to find and activate three strange structures called "Perch" mechanisms within the fog. This is the core mechanic for Day 1. The trick is to use the mini-map—even in the fog, your character icon moves. Follow it, and you'll eventually stumble onto the Perches.

Question 3: What's the deal with those stone puzzles? They feel impossible.

There's something satisfying about solving a good puzzle—after all the frustration, finally, that click. But in my first year (2021), I made the classic mistake of treating the "Stone Slate" puzzles like combat challenges. They're not. They're logic puzzles where you need to activate the correct sequence of stones.

The surprise wasn't the difficulty. It was the lack of in-game hints. You're basically left to figure it out. What I learned: look for patterns. The stones usually have a sequence visible on nearby terrain or ruin walls. Screenshot the pattern, then match it.

If you're stuck on the "Relay Stone" puzzles—where you need to connect electro currents—I've never fully understood the physics myself. My best guess is it's about creating a path. I used a walkthrough for those. I'm not ashamed. The mistake would have been trying to figure it out for another hour.

Question 4: How do I complete the "Tsurumi Island Quest Puzzle" on Day 1?

On Day 1, you need to clear the fog from the Autake Plains. This involves activating three Perches. After that, you're directed to the Chirai Shrine. The pitfall most players hit: they don't realize the shrine has its own set of puzzles involving Feather mechanisms.

I once spent 45 minutes near the shrine looking for a switch. 45 minutes. I checked all four corners. I climbed a nearby cliff. Nothing. Then I realized I hadn't talked to the Ghost of Chirai (a blue spirit standing in plain sight). The quest progress gates behind that dialogue. That's the trick. $20 worth of my time wasted. Lesson learned: Talk to every ghost NPC.

Question 5: I keep dying even though my stats are good. What am I doing wrong?

People assume high HP and ATK stats mean you can tank the environment. What they don't see is that Tsurumi's "Blight" effect damages you over time when you're in the fog, regardless of your white stats. Your gear doesn't help you here. (Should mention: use a healer like Barbara or Kokomi in your party.)

The real danger isn't the mobs. It's the environmental damage draining your health while you're trying to solve puzzles. I'd rather spend 10 minutes explaining this than watch another player panic-resurrect mid-puzzle. An informed player asks better questions: "What food buffs should I bring?" Answer: anything that provides continuous healing, like Sweet Madame or Dragon Beard Noodles.

Question 6: Can I complete Tsurumi Island in one real-time day?

Look, you can physically finish the initial quest chain in about 2-3 hours if you know what you're doing. But the full island—all the world quests, all the chests, the "Through the Mists" Achievement—that takes multiple in-game days. The game resets part of the fog mechanic each IRL day, so you'll need to log in on different days to progress.

My mistake: I tried to grind it all in one sitting. Bad idea. The burnout was real. Space it out over 2-3 days. (And remember, the islands are tied to "Blood Moon" phases, which are on their own schedule.)

Question 7: Is harmon related to any puzzle? Or is it just a location name?

If you're searching for "harmon" in relation to Tsurumi, you're probably looking for the "Harmonia" word found in theorycrafting communities. It's not an official quest term. The closest mechanic is the Harmonious Resonance from some weapon lore—but in practice, Tsurumi's puzzles are about feather and stone teleportation. Don't overthink it. Focus on the game mechanics I've described.

Question 8: Anything else I should know about the island?

Oh, and the "Henry vs Lions" keyword? Not related to Tsurumi Island in any way. If you Google that while playing, you'll be confused. I checked. Just focus on the island—it's worth exploring despite the initial frustration.

The best part of finally completing Tsurumi's quests: the chest rewards and the feeling that you outsmarted a very foggy island. (Finally!).

— Happy adventuring.
