Demon Slayer hits differently after dark. At Nijigen no Mori, you get a day mystery-solving walk plus an evening projection mapping night walk tied to Demon Slayer: Kimetsu no Yaiba. The standout for me is the chance to see character displays with original ufotable artwork that’s specific to this venue.

I especially like how the daytime event turns the Flower-Falling Village setting, called Hanafuru-sato, into an active game. You’re not just looking at sets; you’re solving puzzles as you move through the area, including the Illusion of the Demons theme.

One consideration: plan for real walking, and it’s not a sit-down show. The evening program includes a 1.2 km night forest walk, and the daytime portion involves moving between puzzle points outdoors.

Quick take: what matters most here

• Daytime mystery game in Hanafuru-sato focused on solving puzzles rather than passive sightseeing
• Original ufotable character panels made for Nijigen no Mori
• Night Walk: Path to the Infinity Castle with projection mapping after sunset
• You’ll be on your feet during both parts of the event, including a 1.2 km night route
• A tighter “theme-world” feel than a full amusement park, since much of it is outdoor puzzle stations

Price and what you actually get for $13

At about $13 per person, this event is priced like an attraction that’s trying to be accessible. You’re not paying for a typical theme-park bundle with lots of ride types. You’re paying for one Demon Slayer-focused experience with two distinct halves: a daytime puzzle walk and an after-dark projection night walk.

That matters because your sense of value will depend on what you want. If you love the series and enjoy solving problems while walking outdoors, $13 can feel like a fair trade. If you came expecting a big, ride-heavy park day, you may feel that it’s more “route + puzzles” than “attraction overload.”

The good news: the event includes multiple creative components—puzzle gameplay, character displays with ufotable art, and projection mapping—so it’s not only one gimmick. The watch-out: much of it is physical movement, so comfortable footwear isn’t optional.

Two-part flow: how the day and night fit together

This collaboration runs from March 15, 2025 to December 14, 2025. It’s designed around two time blocks: a daytime mystery-solving walk and an evening night forest walk.

Think of it as two different moods:

• Daytime is about figuring things out in Hanafuru-sato (the Flower-Falling Village).
• Evening is about atmosphere, light, and motion as the story-world shows up around you via projections.

If you can schedule both halves, you’ll get the most from the collaboration concept. The daytime part sets the tone like a game. The night part turns that world into something you experience through visuals.

Daytime: the Hanafuru-sato mystery-solving walk and Illusion of the Demons

The daytime event is a mystery-solving walk called Hanafuru-sato and the Illusion of the Demons. The point is simple: you move around the themed area, you encounter character-themed visuals, and you solve puzzles as you go.

Why this works well: puzzles give you a reason to slow down and pay attention. Instead of glancing at signs and panels, you have tasks that nudge you to read, compare, and connect details. It’s also easier to engage with if you’re traveling with friends because the experience naturally becomes collaborative: one person spots something, another person tests the solution path.

What to watch for: this isn’t described as a “ride” format. It’s an outdoors walk with game mechanics. That means you should expect steady movement rather than a few highlights spaced far apart. If you don’t like puzzle-style attractions, the value drops quickly, since much of the event is made of that walking + solving structure.

UFOTABLE character panels: seeing Demon Slayer art in a dedicated space

One of the most practical reasons to pick this event is the inclusion of character panels featuring original illustrations by ufotable. These panels are exclusive to Nijigen no Mori for this collaboration, so you’re not just collecting generic anime decor.

I like this type of design choice because it treats the art like part of the experience, not a background afterthought. When character visuals show up exactly where you need them for the puzzle flow, it helps the themed world feel “built” rather than stickered on.

Also, these panels can be a nice fallback if you’re unsure about the puzzle mechanics. Even if you move faster or slower than the game rhythm, you’re still getting visual rewards from the art style itself.

Evening: Night Walk through the forest on the Path to the Infinity Castle

After dark, the event shifts into Night Walk: Path to the Infinity Castle. The evening highlight is a 1.2 km walk through a night forest with projection mapping and more.

This is the part that feels like the series has been turned into spatial storytelling. Projection mapping is a strong match for anime worlds because it can transform surfaces and cues without requiring permanent structures everywhere. In a night forest setting, light effects usually land harder, since you’re already in a darker environment and your attention locks in quickly.

Practical reality check: this is still a walk. A 1.2 km route at night is long enough to matter if you’re standing around earlier, rushing between parts of the day, or wearing shoes that aren’t made for uneven outdoor ground.

If you’re someone who likes photos, you’ll probably want to plan for low-light conditions too. But even if you skip photos, the point remains: the visual show is tied to movement. You experience it as a journey, not as a single stationary viewing spot.

Rules you should know before you go

This event has a straightforward policy: no alcohol and no drugs, and no firework. It’s also not designed for every body type or age range. It is not suitable for:

• Pregnant women
• Wheelchair users
• People over 70 years

I mention this because it affects comfort and safety. This is a walk-based, outdoor puzzle + night route experience. If you’re on the edge of mobility or stamina, you’ll want to think hard about whether you can do both parts comfortably.

What the short reviews hint at (without the doom-and-gloom)

Across the feedback I used for this write-up, one message shows up clearly: expect more walking than many people first imagine. That’s not a flaw, but it’s a common mismatch. The experience is structured like a route through themed zones, so the “start-to-finish movement” is the main content.

Another message is about expectations. Some people felt it was not a full park in the way they expected, framing it more as puzzles outside with character signage. That’s a fair way to describe the format based on the structure: you get puzzle walk and a night forest walk, plus projections. You’re not getting a list of ride experiences.

So here’s the balanced takeaway: if you like puzzle walks and anime-themed night visuals, you’ll likely find it enjoyable for the price. If you want a large set of activities with lots of variety beyond walking and puzzles, you may feel underwhelmed.

Tips to make the puzzles and night walk feel worth it

Here are the choices that tend to make or break this kind of event.

Wear walking shoes (and wear them now, not later). You’re doing daytime movement plus a 1.2 km night forest walk. Any foot pain will steal attention from the story-world and the puzzles.

Give yourself time. This is not built around quick in-and-out viewing. The daytime part is a mystery-solving walk, which naturally takes time because puzzles require reading and decision-making. Build your schedule with extra breathing room.

Bring the right mindset for outdoor puzzles. Some puzzle attractions feel slow if you treat them like a scavenger hunt where you want instant answers. Instead, treat it like a story game: slow down, compare what you see, and follow the puzzle logic.

Plan your day so the night part stays enjoyable. If you rush the daytime section and then scramble to make the night walk, you’ll feel it in your stamina. The evening experience is the payoff, especially with projection mapping in a forest setting.

Who should book this Demon Slayer collaboration (and who should skip)

This event is a good match if you:

• Love Demon Slayer: Kimetsu no Yaiba and want a collaboration built around the story-world
• Enjoy puzzle-style attractions where the fun is in solving and moving through themed areas
• Like night-time experiences with light effects like projection mapping

You might reconsider if you:

• Want a traditional amusement-park day with many ride types
• Don’t like puzzles and prefer straight sightseeing
• Have limited mobility or fall into categories listed as not suitable (pregnancy, wheelchair use, or age over 70)

Also, if you’re traveling as a group, this is one of those experiences where cooperation can help. Puzzles tend to work better when people can talk through clues rather than rushing.

Booking and schedule reality: dates and flexible payment

The collaboration is scheduled from March 15, 2025 to December 14, 2025. If you’re planning a Japan trip in that window, it’s worth checking the exact day availability when you book.

On the practical side, there’s a reserve & pay later option—meaning you can book your spot now and pay later. That’s handy if you’re still finalizing your itinerary.

Should you book Awaji: Demon Slayer Nijigen no Mori Puzzle Walk & Projection?

If your dream trip includes a Demon Slayer themed game in Hanafuru-sato during the day and a projection mapping night walk on the Path to the Infinity Castle, then yes, this is likely worth booking. The combination of ufotable character panels, an actual mystery-solving format, and the evening 1.2 km night route makes the $13 price feel reasonable—especially if you’re the type who enjoys being active on your holiday.

If you’re looking for an easy, mostly seated attraction with minimal walking and lots of different ride-style options, skip this one. Based on the structure, it’s built around puzzles and walking, not a classic park checklist. In other words: don’t buy it if your feet hate you.
