Free Hattori Heiji Coloring Pages: 21 printable PDF designs of the Detective Conan character, both alone and alongside his closest friends from the series. Every page can be downloaded as a PDF or filled in through the online coloring tool, and neither option requires signing up for anything.

Heiji Hattori is a high school detective from Osaka in Gosho Aoyama’s manga and anime series Detective Conan, known within the story as the Great Detective of the West. He was the second character to figure out that Conan Edogawa is secretly Shinichi Kudo. That shared secret is part of what makes their friendship a recurring focus across this collection. About half the pages show Heiji on his own; the rest pair him with Kazuha Toyama, Conan, or Shinichi.

The 21 pages are split into three groups: solo Heiji portraits, scenes with his childhood friend Kazuha Toyama, and pages featuring Conan or Shinichi Kudo. Because Heiji’s design stays fairly consistent across the collection, the main coloring decision throughout is his signature dark school uniform rather than a wide range of outfits or settings.

What Is Inside This Collection

Three relationships anchor this 21-page set: Heiji on his own, Heiji with Kazuha, and Heiji alongside Conan or Shinichi, and each group leans on a different part of the character’s role in the story.

Solo Heiji Portraits

The largest group by far is Heiji on his own, mostly variations on the same basic pose and school uniform under different file names. Coloring suggestion: use his uniform’s dark navy or black jacket paired with a lighter shirt underneath, and keep this combination consistent across every solo page so the repeated portraits still read as a cohesive set.

With Kazuha Toyama

This group pairs Heiji with Kazuha Toyama, his childhood friend from Osaka. Coloring suggestion: give Kazuha a distinct color palette from Heiji’s, since the two are drawn close together on most of these pages, and clear color separation helps each character stand out individually.

With Conan or Shinichi Kudo

These pages show Heiji alongside Conan Edogawa or Shinichi Kudo, the two identities of the series’ central detective. Coloring suggestion: keep Conan’s smaller, child-sized proportions and Shinichi’s older teenage build clearly different in scale, since getting that size contrast right is part of what makes these pages read correctly.

What Hattori Heiji Coloring Pages Do

Small, defined edges to follow. A school uniform’s collar, tie, and jacket seams give a child small, defined edges to follow carefully, which aligns with the kind of precise line control the American Academy of Pediatrics associates with fine motor development in structured coloring for children ages two through seven.

A friendship built on trust. Heiji is one of the only characters in the series who knows Conan’s real identity and deliberately keeps that secret, which gives the pages showing the two of them together a real, specific reason behind their closeness rather than a generic friendship with no explanation.

Focused attention, on and off the page. Solving a mystery takes sustained, detail-focused attention, and coloring one of these pages asks for a similar kind of unhurried concentration, the same quality a 2005 Art Therapy Journal study linked to reduced anxiety in adults after structured coloring sessions.

Two cities, two detectives. Heiji represents Osaka in the story the way Shinichi represents Tokyo, each known as the great detective of their half of Japan, so a page with both characters doubles as a small, concrete way to talk about regional identity within a single country.

How to Color Hattori Heiji Pages Well

  • School uniform: color Heiji’s jacket in a deep Crayola Navy Blue or Black, with a crisp white or pale blue shirt underneath, and keep this combination the same across every solo portrait.
  • Skin tone: Use a warmer Crayola Copper or Burnt Sienna for Heiji’s skin, since the character is consistently drawn with a noticeably tanned complexion compared to some other cast members.
  • Hair: keep Heiji’s hair a solid Crayola Black, since his short, simple hairstyle doesn’t need shading detail the way a longer or more textured style might.
  • Kazuha’s pages: give Kazuha a lighter, brighter color scheme than Heiji’s darker uniform, which helps the two characters read as visually distinct even when drawn close together.
  • Conan vs. Shinichi: use the same color palette for both, since they’re the same character, but keep Conan noticeably smaller in every proportion to preserve the visual joke of his shrunken form.
  • Background details: since most solo pages use a plain or minimal background, save any bold background color for the group scenes specifically, which keeps the simpler portraits from feeling unfinished by comparison.

5 Creative Craft Ideas With Hattori Heiji Coloring Pages

1. East vs. West Detective Cards

Color a Heiji page and a Shinichi or Conan page, then label them “Great Detective of the West” and “Great Detective of the East” for a simple matched card pair.

2. Friendship Duo Bookmark

Color one of the Heiji-and-Conan pages, cut it into a tall bookmark shape, and cover it with clear tape for a durable reading marker.

3. Kazuha and Heiji Greeting Card

Color one of the Kazuha pages and fold it into a card for a friend, since the pair’s dynamic works well as a lighthearted, friendship-themed greeting.

4. Detective Case File Folder

Color a solo Heiji page and glue it to the front of a plain folder to make a personalized “case file” folder for homework or drawings.

5. Mini Character Gallery

Color a few different pages from the set and arrange them together on a board or wall as a small character gallery.

Who is Heiji Hattori in Detective Conan?

Heiji Hattori is a high school detective from Osaka, created by Gosho Aoyama, known in the series as the Great Detective of the West. He first appears partway through the story and becomes one of the central character Shinichi Kudo’s closest allies.

Who is Kazuha Toyama, and why does she appear so often?

Kazuha Toyama is Heiji’s childhood friend from Osaka, and the two share an unspoken mutual attraction throughout the series, which is why she appears alongside him across several pages in this collection.

Why do some pages show Conan Edogawa and others show Shinichi Kudo?

Conan Edogawa and Shinichi Kudo are the same character; Shinichi is the original high school detective, and Conan is the child-sized identity he takes on for most of the story. Both names describe the same person at different points in the plot.

Does this collection reveal major plot details from the series?

No. The pages focus on the characters’ appearances and general relationships rather than depicting specific mysteries, twists, or story events.

Can these pages be colored without printing them?

Yes. Every page in the set opens directly in the site’s browser-based coloring tool, so a page can be finished on screen before deciding whether to print it.

Are Hattori Heiji coloring pages suitable for young children?

The solo portrait pages use one clearly defined figure and suit a wide age range, including younger children. At the same time, the multi-character scenes ask for a bit more patience and attention to detail, making them a better fit for an older child already comfortable coloring inside the lines.

Why do so many pages repeat the same basic Heiji pose?

Most of the collection uses one core portrait style with different file names rather than a wide variety of scenes, which makes the smaller groups featuring Kazuha, Conan, or Shinichi the best place to find real visual variety within the set.
