🚂 JAM2026 FLASH REPORT: Micro Ace Goes ABSOLUTELY WILD — Nankai 20000 “Koya” Confirmed & A Ton of N Gauge Prototypes Revealed!

Okay, train model fans — strap in, because Micro Ace just straight-up went OFF at JAM2026 (the 25th International Model Railway Convention) and if you weren’t at Tokyo Big Sight from August 21–23, 2026, you are absolutely feeling the FOMO right now. Don’t worry, I’ve got you covered with this full flash report straight from the floor. 🇯🇵🔥

What Is JAM2026 & Why Does It Matter?

For the uninitiated: JAM (International Model Railway Convention) is Japan’s absolute biggest, most prestigious model railway event — held annually at Tokyo Big Sight. This year’s 25th edition ran across South Halls 1 & 2, and the theme for 2026 was “Shinkansen and the Eve of Its Opening.” Every major N gauge manufacturer was there flexing their upcoming lineups, and Micro Ace? They came to absolutely body the competition. 💪

🔥 THE BIG HEADLINE: Nankai 20000 Series “Koya” — OFFICIALLY CONFIRMED FOR PRODUCTION!

This is the one that had the whole floor buzzing. Micro Ace has officially confirmed the production of the Nankai 20000 Series “Koya” — and this is a HUGE deal. The Koya is one of those legendary, iconic Japanese limited express trains with that unmistakable retro elegance, and it’s been a long time coming for a proper N gauge release. Seeing it displayed for the first time at JAM2026 was genuinely a moment. Rail fans and N gauge collectors have been waiting on this one, and now it’s real. This is grail territory. 🏔️

🚃 Prototype Showcase: Everything Micro Ace Put on the Table

Beyond the Koya headline drop, Micro Ace had a stacked lineup of prototypes on display — and every single one of them is a reason to open your wallet. Here’s what was shown:

• JR 223 Series (Type 0) — The classic JR West commuter/rapid train getting the Micro Ace N gauge treatment. Clean, detailed, and looking sharp under the booth lights.
• Series 113 in JR Tokai Specification — The beloved 113 series rendered in that distinct JR Central color scheme. Nostalgia levels: maximum. Orange stripe fans, this one’s for you.
• Toei Subway Shinjuku Line 10-300R Formation — The retired 10-300R type that once ruled the Shinjuku Line is getting immortalized in N gauge form. A fantastic prototype pick for Tokyo transit enthusiasts.

And that’s not even everything — the booth was packed with even more display pieces, including the Izukyu Saro 2183 Royal Box and the EF52-7 Ryuka Locomotive Depot Special Decoration variant. Micro Ace clearly came with a full deck this year. 🃏
