Ichima-San is a compact action-adventure title from publisher Game Games that puts an unusual spin on the stealth genre. You play as a person whose human body has been taken away, leaving you trapped inside an Ichimatsu doll — one of those traditional Japanese dolls with a painted face and stiff, jointed limbs. Your only way out is to explore a traditional Japanese house, gather items that restore your abilities, and avoid being seen by the humans who live there. The premise is small in scale but specific, and that specificity is exactly what makes the game stand out.

This page covers the eShop NSP release plus the 1.1.0 update package (build v131072), the base title ID 0100EA502083A000, and what you actually get when you install both files. If you're running the game through a Switch emulator on Windows, Android, or iOS, the NSP format is the one you want.

Technical Specifications

What Ichima-San Actually Asks You to Do

The core loop is built around three verbs: explore, collect, and hide. You move through a traditional Japanese house that is, by design, occupied — humans are present, and they are the threat. Rather than fighting them, you avoid their line of sight entirely. The description is explicit about the fail state: you mustn't allow yourself to be spotted.

The escape hatch when you're about to be seen is the doll conceit itself. You can play dead, going limp and inanimate exactly as a real Ichimatsu doll would. It's a clever mechanical justification for a stealth ability, and it means your survival depends more on timing and reading a room than on reflexes.

Progression comes from item hunting. Hints point you toward objects scattered through the house, and each one you recover enhances your abilities. That structure gives the game a clear rhythm: learn the layout, find the next hint, grab the item, deal with the humans standing between you and it. Because the doll body is limited, those ability upgrades are what gradually open up parts of the house you couldn't reach before.

Key Features

• Doll-based stealth: You inhabit an Ichimatsu doll, which means your movement and your options are constrained in ways a normal protagonist's wouldn't be.
• Play-dead mechanic: When a human is about to spot you, you can go inanimate to avoid detection — a direct, readable escape tool rather than a hidden stat check.
• Ability-enhancing item hunt: Hints lead you to items that expand what you can do, so exploration and progression feed each other.
• Traditional Japanese house setting: A single, carefully themed environment rather than a sprawling open world.
• Action-adventure framework: Movement, evasion, and collection sit at the center; combat is not the focus.
• Bilingual support: Japanese and English text are both included.
• Small footprint: The base game is 465 MB, so it fits comfortably on limited storage.

Pros & Cons

Pros

• The Ichimatsu doll premise is genuinely distinctive and ties directly into the stealth mechanic instead of being decorative.
• Playing dead is an intuitive, immediately understandable way to handle being spotted.
• The item-hunt structure gives you a steady sense of progress without padding.
• At 465 MB, the download is quick and the install is light on storage.
• Both Japanese and English are supported, so you can play in either.

Cons

• The scope is deliberately small — one house, a focused item list — so players looking for a long campaign may find it short.
• Stealth that punishes detection can be frustrating if you prefer action over patience.
• As an eShop-only release, there's no physical version to fall back on.
• The base NSP alone doesn't include the 1.1.0 fixes; you need the update file too.

Version 1.1.0 (v131072) — What the Update Adds

The 1.1.0 update is distributed separately from the base game and carries build number v131072. It's the current update package listed for this title. If you already have the base NSP installed, grabbing just the update is enough; if you're starting fresh, install the base game first and then apply the update on top. Keeping the two in sync matters because save data and title behavior are tied to the installed build.

Note that no official changelog text was published alongside this listing, so treat any claim about specific fixes in 1.1.0 with caution — the version number and build are confirmed, the contents are not documented here.

Who This Is For

Ichima-San suits players who like stealth built around observation rather than combat, and who appreciate a setting with a strong cultural identity. If you've enjoyed small-scale Switch eShop adventures with a single clever hook, this fits that mold. It's also a reasonable pick for younger players or anyone who wants something atmospheric without a heavy time commitment — the language support covers English, so you don't need Japanese to follow it.

If you lean toward rhythm and music titles instead, you might also want to look at Groove Coaster Future Performers Switch NSP + Update (eShop), which sits in a completely different genre but follows the same eShop NSP release pattern.

Version Freshness and Publisher Details

The 1.1.0 build (v131072) is the newest update listed for Ichima-San, and it's the one bundled on this page alongside the base NSP. The title was published by Game Games on November 21, 2024, with development credited to Joker2.0. Title ID 0100EA502083A000 is the identifier you'll see in your Switch's software list and in emulator library views — matching it against your installed copy is the quickest way to confirm you're looking at the right game and not a similarly named release.

Because this is an eShop title, there's no cartridge version, and updates arrive as separate NSP files rather than being baked into a single package. That's standard for the format, but it does mean you should keep track of which build you have installed.

Practical Installation Guidance

If you're running Ichima-San on a Switch, install the base NSP first, then the update NSP, using your usual NSP installation tool. On emulators for Windows, Android, or iOS, add the base game to your library and then apply the update file to the same title entry — the emulator should recognize both as belonging to title ID 0100EA502083A000. Don't skip the update if you plan to rely on save data, since mismatched builds between base and update can cause the game to behave inconsistently.

Storage is not a concern here: at 465 MB for the base game, the download finishes quickly on most connections, and the update package is smaller still. If you're managing a library of Switch NSPs, this is one of the lighter entries you'll add. For a heavier, more content-dense alternative in the same eShop category, see Minecraft Switch NSP + Update + DLC (eShop).

Final Thoughts

Ichima-San earns its place through a single strong idea executed with focus: you are a doll, you are fragile, and the house is full of people who would notice you. The play-dead mechanic and the ability-item hunt give that idea real mechanical weight. It won't satisfy players who want a sprawling adventure, but as a tight, atmospheric stealth title with a memorable premise, it's a solid addition to an eShop library — and at 465 MB, trying it costs you very little.
