Have an idea you’d love to try? Tell me about it. It could be fun to bring it to life together!

I promise confidentiality from the outset. If the situation calls for it, I won’t share any of it on TikTok.

As for what I can bring to the table, I have a talented team member called ChatGPT.
An exceptionally capable one, for ¥30,000 a month.
By the way, they earn more than I do.

Let’s chat over coffee lol

About me

A question often begins
with something I love.

I'm Shosuke Kuroda. I love the Joban Line's E231 series and Emilia from Re:ZERO. The things that catch my attention lead me into research, experiments, journeys and notes. I keep the process, including the moments that change my mind.

A little more about me

Website contribution

Creating
Matrain’s website.

A contribution to Matrain’s published website, from information structure to wording and presentation.

Information structure, pages, words and publication

From structure to publication.

I contributed to information structure, page planning, wording and presentation, revisiting the existing Google Sites version and the order in which people encounter its content.

AIM: Help a first-time visitor understand the materials and activities.
CONSTRAINT / CHOICE: Give each page a role instead of presenting everything at once.
RESULT: A published website and a record of my contribution.

Railways & journeys

A familiar green.
A reason to go further.

The E231 series on the Joban Line is a favourite. Following that interest has taken me to stations, local places and the sounds I want to remember.

February 2026

Original travel plan. A personal journey.

What is worth making the trip for?

For a Kyun Pass journey, I worked out how to combine Shinkansen travel, station-melody recording and time in each place. Time, cost and missed connections were constraints; a written plan made the choices visible.

Documents & iterations

Make it. Read it.
Make it clearer.

Travel proposals, schedules, learning notes and visual experiments. I keep the original material as well as the choices behind it.

Original screen or document

A favourite character. A serious design exercise.

Nineteen ways to rethink a chart.

Using Emilia as a subject, I revised the same chart repeatedly, reconsidering lines, colours and labels to see what deserved attention.

AIM: Explore how presentation changes the reading of the same data.
CHOICE: Remove unnecessary lines and scales before adding emphasis.
RECORD: All 19 iterations are available. The figures are fictional and subjective, used for play.

Also in the archive: travel proposals, schedules and reflections, and a travel-service outline in English.

An open notebook

A good story

Re:ZERO's English dub, overseas videos and books. I collect unfamiliar expressions and ideas, leave them in context, and return to them. The notes are part of an ongoing practice.

The idea archive

A platform I am building to keep an idea, its mechanism, a simple demo and the questions still open in one place. For now, this is an introduction to the archive; individual entries and demos are not public yet.

The story of this name

An idea ended. The questions stayed.

This domain began with Sakasama Furima, a buyer-first marketplace I tried to build. It closed. I kept the name as a place to record what I try, what changes, and what comes next.
