KADŌ is a quiet flower-arranging puzzle built around the kenzan — the spiked metal frog a Japanese arranger presses stems into. You never drag a branch by hand: you pick a branch from the cards at the bottom, turn a large angle dial to choose how it will lean (the dial snaps to a set of clean angles), then tap an open hole on the kenzan to seat it there. A finished arrangement has to obey two things at once: no two branch lines may cross, and each branch belongs to one of the three, the sansai — heaven stands nearly upright, human leans on the diagonal, and earth lies low. Every stage has a single correct arrangement, always reachable by reasoning rather than luck; a reference hint reveals one branch's angle, and a limited undo lets you take a move back and rethink. 200 hand-checked stages on a gentle curve, seasonal backdrops, and 12 languages. Now on Roblox; Android testers welcome on Google Play; coming soon to the App Store.

HANKO is a quiet Japanese seal-carving logic puzzle, and the idea runs backward on purpose: the parts you do NOT carve are the parts that print. Tap cells to carve grooves into a seal face; what remains raised takes vermilion ink and stamps onto the washi paper below, inside one to four fixed guides. A cell covered by one guide prints light red, and where prints from two guides overlap the ink doubles into a deep dark red, so your print must match the target exactly — blank, light, or dark. After each press you are told only how many cells came out too dark and how many too light; no cell is pointed out for you. Carving is one-way, so plan before you cut. 200 hand-checked stages, a daily seal with a streak, a stamp book, and 12 languages. Play now on Roblox; coming soon to the App Store and Google Play.

A first-person, on-rails space shooter with a Japanese ink-wash look. Drag to paint lock-ons over the incoming swarm of meteors and drones, then release a fan of homing light-arrows that chain a whole cluster in one breath. Fly through sectors from launch to the deep, grab shields, ride the overdrive, and take on an endless meteor storm. Play now on Roblox; coming soon to the App Store and Google Play.

Okaeri is a cozy pet homecoming slide puzzle. Slide a row or column of glassy food bowls; bowls wrap from one edge to the other. When a whole line becomes one pet's favorite food, that pet crosses the board. Then rotate the outer ring, where pets and owners wait, so the matching owner is on the far side. Reunite every pair to clear the stage. Calm stages, no timer, and 12 languages. Out now on the App Store and Roblox; Android testers welcome on Google Play.

Shizuku is a cozy, deterministic physics puzzle set in a quiet Japanese garden. You never touch the dewdrops — instead you arrange the board: place bamboo flumes, stones and leaves so that, when two drops fall, they roll, slide and finally meet to become one. Set the scene, release the drops, and watch your plan play out. Because nothing is random, you can think the whole run through before you let go. Calm, hand-made levels and no time pressure. 12 languages. Out now on the App Store and Roblox; Android testers welcome on Google Play.

SENKO is a cozy, two-phase smoke puzzle. Light a stick of incense and a restless dark smoke rises — sweep it with your finger to calm it until it settles and turns clear and white. Then guide that white smoke to fill a faint Japanese motif: the moon, a pine, a crane, cherry blossoms and more, across 120 quiet stages. Watch for red embers — touch one and it burns your smoke back, so weave around them. The smoke is finite, so shape it before the incense burns down. A fan calms broadly and a brush helps you shape. No pressure, 12 languages. Out now on the App Store and Roblox; Android testers welcome on Google Play.

WAGASHI is a cozy Japanese-sweets merge puzzle. Drop a sweet into the vessel; when two of the same touch, they merge into the next, climbing a 10-step chain from a tiny azuki bean all the way to a grand kagami-mochi. Round sweets roll and settle with soft physics — just don’t let one come to rest above the warning line. Play it two ways: an endless, calm Zen mode, or 60 order stages where you fill a request within a limited number of moves. A fan and a pair of chopsticks help you nudge and re-place, and a “Next” preview lets you plan each drop. No pressure, 12 languages. Now on Roblox; Android testers welcome on Google Play; coming soon to the App Store.

A cozy, minimalist mirror-twin grid puzzle. One swipe moves two twins — Gold (a warm golden glass drop) and Platinum (a cool silver-white glass drop) — one cell each in opposite, point-symmetric directions. Walls and edges stop one twin but not the other, so you use that desync to rest both in their matching-color holes, inside a little brass tally counter. 120 levels in 7 families. Free, made by PixelRyu. Out now on the App Store and Roblox. Android in open testing on Google Play.

A cozy block puzzle where you lay tatami mats in a quiet Japanese room. Drag a mat onto the floor and complete a full row or column to finish that line. A samurai then carries the finished mats to the tatami magistrate, and delivering earns koban that buy extra lives. A light Haste gauge keeps you moving. With a lucky-laying bonus. 48 stages. Free, made by PixelRyu. Coming soon to the App Store.

A first-person paddle breakout in a cozy Japanese night. Move your hagoita with a fingertip, keep the temari in an endless rally, and pop every paper balloon down the corridor — with split, focus, a pheasant helper and more. 8 worlds, 200 stages. Out now on the App Store.

A cozy maze-escape puzzle. Fire yarn from outside the maze, ride the ricochet, and shift or shatter walls so the trapped cat finds its own way out — 200 mazes across 10 worlds. Out now on Roblox and the App Store. Android testers welcome.
