Touhou Tenkuushou(Heavenly Jade Dipper) ~ Hidden Star in Four Seasons (東方天空璋 ~ Hidden Star in Four Seasons) is the sixteenth official installment of the Touhou Project. It was announced by ZUN on his personal blog on April 20, 2017, at 22:09 JST.[1] A playable demo was released May 7, 2017, at Reitaisai 14, and the full version was released August 11, 2017 at Comiket 92. It was launched on Steam on November 17, 2017, marking Touhou's debut on the platform.


There are four playable characters, each of which has a season assigned to them that determines their shooting type (main season): Reimu Hakurei (spring), Cirno (summer), Aya Shameimaru (fall) and Marisa Kirisame (winter). In addition, a sub-season is initially selected, in which again the four seasons, as well as for the extra stage a fifth, the ex-season.

Shooting enemies, completing Spellcards and Graze creates Season Items, which drop down like other items and can be collected by the player, slowly replenishing Options. Pressing the Release button (default: C) consumes all Options for a Season Release, which can convert orbs into green point items that permanently increase the value of blue point items in a pattern that depends on the sub-season.

The Season display of the summer sub-season to a little under 3 Options.

  • Spring (Main Season) (Reimu Hakurei): homing cherry blossom petals, little difference between focused and unfocused shot. Number of shots determined by power. Bomb: Large cherry blossoms that circle around the player, destroying bullets and then falling into the boss.
  • Spring (Sub-Season) (selectable): A toned-down version of the main season, weak target-seeking shots; Release: Relatively large circle that transforms all the orbs in it in one hit, diameter varies between small and full-screen depending on options. A significant amount of invincibility is granted depending on the level of the release.
  • Summer (Main Season) (Cirno): Ice crystals in a wide spread that increases when powered and decreases when focused. Bomb: Huge, stationary ice flake that causes permanent damage.
  • Summer (Sub-Season) (selectable): Release: Small circle that persists for a brief moment, but only consumes one option.
  • Autumn (Main Season) (Aya Shameimaru): Unfocused wind gusts fly in a slight dispersion, focused ones straight ahead and penetrating. Width determined by power for both types. Bomb: Relatively narrow vertical stationary streak with continuous damage in comparison.
  • Autumn (sub-season) (selectable): Side shots aimed upwards. release: small circle that follows player, duration dependent on options; speed increases during release.
  • Winter (Main Season) (Marisa Kirisame): Laser with power-dependent dispersion or straight path when focusing. Bomb: Marisa's well-known "Master Spark", a big, wide laser above the player, which can only move slowly
  • Winter (sub-season) (selectable): Release: Medium circle that stays for a while; size and duration depend on options; shooting power is slightly boosted during release.
  • Ex-Season (Sub-Season) (only in Extra Stage): Straight with a slight spread and high damage shooting backwards; Release: Like Summer, but with a slight downward movement while shrinking.


Stylistically, Hidden Star in Four Seasons is very varying , with the atmosphere varying from melancholia, intoxicating, or even threatening, which fits well with the environment of the mixed seasons.

In Hidden Star in Four Seasons, ZUN wanted to return in some form to the Touhou parts of the early Windows era. As in older parts, the player is rewarded with Extends through higher scores, the game's own mechanics are significantly less complex than in its predecessors, and the difficulty drops again after Legacy of Lunatic Kingdom. This game's third stage also marks Lily White's first midboss appearance since Great Fairy Wars.


The "Hidden Star" in the title is referring to Okina Matara, a hidden god of stars. The character in the Japanese half of the name also refers to a dipper, the shape of the constellation of the Big Dipper, which Okina holds connections with.


Despite it being midsummer, the seasons in various locations are completely out of whack. Hakurei Shrine is showered in cherry petals, the Youkai Mountain is basking in the middle of autumn, and the Forest of Magic is blanketed in snow. To add to that, thanks to some strange force, Gensokyo's fairies are running rampant with unfathomable strength. In the midst of this undeniable incident, the heroine sets out to investigate and confront the perpetrator behind it.


Hidden Star in Four Seasons has 17 new songs, 7 boss themes, 7 stage themes, a title theme, an ending theme and an arrangement of a stage theme for the Staff Roll.


Hidden Star in Four Seasons was first announced on ZUN's blog on April 20, 2017. He confirmed playable characters and posted in-development screenshots.

He noted that he was aiming for a "light and refreshing feeling" and would like to "return to [his] roots with something that simply aims to make you feel good to play." On May 5, ZUN showed the demo CD that would be released at next Reitaisai.

During the 86th edition of the Nikenme Radio show[2] on October 30th, 2017, ZUN announced that a Steam release for the game was planned. This was also mentioned by Tasofro in a blog entry following the show[3].
