YOUR JAPANESE VERSION
IS PROBABLY BROKEN.

19.9%

Japanese Steam reviews are negative at nearly 20% — that's 4–8 points higher than the global average of 15.6%. Japanese players don't write reviews when they're happy. They write essays when they're not.

11.8K

Hollow Knight: Silksong got 11,800 negative reviews in one language due to bad localization — tanking a 92% positive game to 39%. Team Cherry had to publicly apologize. This can happen in Japanese too.

Here's the worst part: you can't read Japanese, so you don't even know it's broken. Machine translation silently corrupts your game's personality. Your witty dialogue becomes robotic. Your store page looks amateur. Your UI overflows because Japanese text behaves differently.

Players notice. They just stop playing — or leave a review that tanks your score.

FOUR THINGS. ONE PERSON.

01

TRANSLATION

EN→JP game text localization. AI-assisted for speed, human-finalized for nuance. Your jokes stay funny. Your lore stays deep.

02

DTP & STORE ART

Steam store page images, banners, logos — redesigned for Japanese. Not just text-swapped. Actually re-typeset with proper Japanese typography.

03

FONT & UI

Japanese font selection from free & licensed libraries. UI layout adjustments so nothing overflows, truncates, or looks wrong.

04

CULTURAL CONSULTING

Character names, customs, visual details, social norms — I review everything so your game feels authentic to Japanese players, not just translated.

MITSURU KOYAMA

Background

25 years with Adobe tools. 20 years building automated publishing systems. I've built catalog production pipelines for 20+ clients using Adobe, AppleScript, and FileMaker. I know how to ship polished output at scale — print and digital.

Native Japanese

Born and raised in Japan. I catch things a translator never would — the name that sounds weird, the sign that's grammatically correct but no Japanese person would ever write, the honorific that doesn't match the character's age.

One-Stop

Most translators hand you a text file. I hand you finished assets. Translation, store images, UI fixes, cultural review — one person, one invoice, no coordination overhead.

AI + Human

AI for speed. Human for soul. I use AI to accelerate the mechanical parts, then apply 25 years of design instinct and native judgment for the final pass. Fast turnaround, no quality compromise.

Gamer

Puzzle games and RPGs are my thing. I understand game UI conventions, player expectations, and what makes dialogue feel alive. This isn't just a job — I'm your target audience.
