21 Emon Review: The Hotel Heir Who Wanted the Stars, Not the Front Desk

When I was a kid, I thought the worst thing in the world was being stuck where you are. Same town, same routine, same desk. I'd read Doraemon under the covers and wish a door to anywhere would open in my room. So when I finally read 21 Emon — Fujiko F. Fujio's earlier, weirder sci-fi comedy — I felt seen in a way I didn't expect. Here's a boy who lives in a future where aliens check into hotels and space travel is normal, and all he wants is to leave. He wants to be a space pilot. Instead he's the 21st heir to a 400-year-old family inn, stuck behind the front desk, polishing the same lobby his ancestors polished.

I read it slowly, on purpose. It's only four volumes, and once you know it's the seed that grew into Doraemon, every page feels like watching a master figure out what he was really good at.

Quick Take

• Fujiko F. Fujio's sci-fi comedy — a 22nd-century Tokyo where aliens are tourists, anchored to a family hotel that's been running for 400 years
• 21 Emon dreams of being a space pilot, but the universe keeps arriving as guests and chores instead of adventure
• 4 volumes, complete; All Ages — gentle, warm, and funny, with nothing concerning

Who Is This Manga For?

• Fans of Doraemon who want to see Fujiko F. Fujio's warmth applied to space, robots, and a hotel
• Readers interested in vintage sci-fi comedy from the late 1960s, before the genre's Japanese conventions settled
• Anyone who likes the "the dream is right in front of you" tension more than straightforward adventure
• Readers curious about Fujiko F. Fujio's range beyond Doraemon and Perman

Story Overview

The world of 21 Emon is the future — aliens travel to Earth as tourists, space ports are everywhere, and the solar system is open for business. In Tokyo City sits Tsuzureya (つづれ屋), a hotel that has been run by the Emon family for over 400 years. The current heir-in-waiting is 21 Emon, the 21st generation of the line: a hot-blooded, stubborn boy who would much rather be flying among the stars than checking guests in and out.

The engine of the series is that conflict — Emon's dream of becoming a space pilot pulling against his attachment to the family business and the duty handed down to him. He saves tips toward a trip into space, gets pulled back into running the hotel, and gets dragged through one comedic disaster after another. The guests are aliens of every shape; the staff is a robot and an alien who cause as many problems as they solve.

It's episodic by design — Fujiko F. Fujio later said he flipped his usual idea: instead of dropping the extraordinary into the ordinary (a robot cat in a normal kid's room), he set the story in the extraordinary — the future, space — and then mined the ordinary feelings that survive there. A boy who feels trapped, a family that wants him to take over, a girl he can't quite talk to. In the TV anime's finale, a grown-up Emon and Luna are married and running a space hotel together, telling their son 22 Emon about their adventures — the dream of space and the duty of the inn finally reconciled rather than chosen between.

Characters

21 Emon — The 21st heir to Tsuzureya. He's earnest, quick to anger, and torn down the middle: he genuinely loves the old hotel, but his real dream is to pilot a ship into deep space. He hoards tips toward that trip, and his frustration is the comedy and the heart of the series at once.

Gonsuke (ゴンスケ) — A former potato-digging robot who's been taken in as a bellboy. He is obsessed with one thing: growing sweet potatoes. He'll plant a potato field in a hotel guest room if you let him, speaks in a thick rural dialect, and — despite being a robot — is the most expressive, emotionally volatile character on the page. He is the breakout star and, by reputation, the reason a lot of people remember the series at all.

Monga (モンガー) — An "absolute creature" born on the planet Sasayama. He can teleport by shouting his own name, survives vacuum, absolute zero, and searing heat, and tags every sentence with a cute "-moa." He's devoted to Emon and is, ironically, exactly the kind of genuine alien contact Emon claims to want — and takes completely for granted.

Luna (ルナ) — The level-headed daughter of the president of the rival hotel Galaxy. She quietly carries a soft spot for Emon, and the anime's ending pairs them as a married couple running a space hotel.

Art Style

Fujiko F. Fujio's line here is pure late-'60s charm: round, friendly character designs, alien tourists rendered with the same playful invention as Doraemon's gadgets, and a future Tokyo that feels imaginative without ever feeling cold. The hotel itself grounds everything — for all the spaceships and aliens, the emotional center is a warm, slightly shabby family inn.

What I Love About It

I love Gonsuke. Not as a sidekick — as the soul of the book.

He's supposed to be a simple potato-digging machine, a tool. But Fujiko F. Fujio gives him a dream — to grow sweet potatoes — and then takes him completely seriously about it, which is both the funniest and most quietly moving choice in the whole series. There's a stretch where Gonsuke saves up his own tips, rents a leaky room in the hotel, and becomes a paying guest just so he can keep farming potatoes. Suddenly the robot bellboy is a customer, demanding feasts and lording it over everyone, while the hotel's money troubles flip the power balance so far that 20 Emon (the father figure running the place) has to come begging him for a loan. A potato robot, holding the family hostage. It's absurd and it's perfect.

What gets me is that under the slapstick, Fujiko F. Fujio is doing the thing he'd later perfect in Doraemon: he treats a "lesser" character's small dream as if it matters as much as anyone's. That's the warmth people mean when they talk about him. He doesn't laugh at Gonsuke's potatoes. He laughs with the absurd dignity of caring that much about something silly.

Memorable Scene ⚠️ Spoiler Warning

The scene that sticks with me is the end of Gonsuke's potato saga — the "I'll grow potatoes even if it kills me" (死ンデモイモヲ作ルダゾ) episode.

Having become an insufferable paying guest, Gonsuke decides he wants to eat "human food" like a real person. The problem: he's a robot with no tongue, no sense of taste — so he dumps an enormous amount of salt on his meal to feel anything. The salt rusts him from the inside, and his body seizes up and stops moving. After he's repaired and wakes back up, the potato dream is over for him, and he delivers the line the series is remembered for: "My dream is gone… like a fleeting rainbow. If I can't dig potatoes, there's no point in living."

It's played for comedy — a rusted-solid potato robot mourning sweet potatoes in broken dialect — but the phrasing is real poetry, and that's the joke and the tenderness in one breath. A throwaway robot grieving like a tragic hero over a vegetable. I laughed, and then I sat there a second longer than I expected to. That's the Fujiko F. Fujio move: he sneaks the ache in right under the gag.

Pros & Cons

Pros

• Gonsuke alone is worth the read — a genuinely iconic comic creation
• The "flipped" premise (ordinary feelings inside an extraordinary setting) is clever and ahead of its time
• Warm Fujiko F. Fujio charm on every page
• Short and complete at 4 volumes

Cons

• No licensed English edition
• The episodic structure doesn't build toward big dramatic payoffs
• Emotionally lighter than Doraemon
• The late-'60s sci-fi look shows its age

The pacing is gentle and episodic — that's either a flaw or a feature depending on you.

Is 21 Emon Worth Reading?

For Fujiko F. Fujio fans, yes — this is where you watch him discover the formula Doraemon would perfect, and Gonsuke is one of his best comic creations full stop. For a general reader, Doraemon is the smoother entry point. But as a short, warm, inventive sci-fi comedy with a potato-obsessed robot at its heart, 21 Emon absolutely stands on its own.
