Power Calligraphy

Power Calligraphy (リズムお習字) is the 21st Rhythm Game in Rhythm Tengoku, the 3rd Extra Game unlocked with 41 Medals in Rhythm Heaven Fever and the 23rd game in Rhythm Heaven Megamix. It's about a man who is learning how to write Japanese calligraphy.

Gameplay
The player controls a giant hand writing calligraphy with a surprising amount of strength. The giant hand writes automatically, while the player presses Ⓐ or taps to finish the characters with a powerful stroke when the hand reaches enough power. There are six different symbols to write (レ ("Re" Katakana), 、 (a Japanese comma), 力 ("chikara", power), 己 ("onore", oneself), 寸 ("sun", a Japanese kind of measurement), 心 ("kokoro", heart), and the characters つるニハ○○ムし (tsurunihamarumushi) (or つ3ニハ○○ムし in the Korean version) arranged to form a face). Near the end, the game goes faster and people come out dancing.

Skill Star
The Skill Star appears on the first the sun symbol (寸) in the game.

Challenge Land
appears in the following Challenge Train courses:
 * Bringing Topknots Back
 * Game Gamble: Beginner
 * The Soul of Japan

Rhythm o Shuji 2P
This game also appears in the 2P mode of Rhythm Tengoku (Arcade) where it is referred to as Rhythm o Shuji 2P (リズムお習字 2P). It plays the same as the 1P version, except it has a split screen display to accommodate the second player. As a consequence of this design, there is only one column of dancers per screen, and they walk over the paper.

Trivia

 * There is an unused gameplay history screen in Rhythm Tengoku which can be accessed through the debug menu, which lists all the games and things in the Omaku Corner, the average score the player currently has (using a numbering system from 0 to 1000 which is hidden from the player in normal gameplay), and the amount of plays. Among the games is a string reading "リズムお習字 ２", meaning that a Rhythm o Shuji 2/Power Calligraphy 2 was intended, but ultimately scrapped.
 * The "The End" kanji that appears in Japanese version was kept in the international version of Rhythm Heaven Megamix, unlike Rhythm Heaven Fever.
 * In the Korean version, various things were changed, as seen below.
