Mark to Market

Want to build real financial literacy β€” not headlines, but how the system actually works? Breaking into fixed income and want to arrive ahead of the curve? Or simply curious why Japan β€” the world's most indebted major economy β€” is where it is today?

You're in the right place.

Mark to Market is a free, AI-maintained textbook on Japan's economy, monetary and fiscal policy, and government bond markets β€” written to take you to the level a first-year rates professional is expected to reach. Unlike a printed textbook, it keeps itself current: market data flows in from the Ministry of Finance every day, and an AI pipeline re-verifies the key facts against primary sources after every policy meeting and data release. No stale numbers from three editions ago.

Created by Kenta, a non-finance (STEM) major, former strategist and rates/FX trader, fintech founder, and AI (ML/NLP) enthusiast seeking to improve financial education.

🎯 A Word of Advice

If you're a student: use AI every day (ML, not just LLMs) β€” but more importantly, master the fundamentals. In finance, this means mathematics, economics, and history.

Over the next decade, there will be a serious divergence between people who use AI and those who understand their field and know how to apply AI to it.

My Motto:
$$\text{Discretionary} - \text{Quantitative} = f(\text{intuition})$$
Intuition can be optimized through focused learning and pattern recognition, not just years of experience.

Core Knowledge + AI Mastery will create exponential advantage.
