Signing up for an official Bandai tournament used to feel like a small quest. Find the right page, fill in forms, hope the store confirms before slots run out. Since 2024, Bandai has been quietly moving all of that into one free app — BANDAI TCG+. And this summer, it added a deck builder to the lineup. Here's what the whole system does, and how to put it to work.
What BANDAI TCG+ actually is
TCG+ is Bandai's one-stop event app for its card games. The list reads like the back of a booster: One Piece, Gundam, Digimon, Dragon Ball Super Fusion World, Union Arena, and more.
In the app you can find a store near you, apply for tournaments while the window is open, check in on event day, and see pairings and results as they happen. Bandai has leaned on it hard — most official events now say "apply on TCG+" instead of collecting sign-ups in store. It's free, on both the App Store and Google Play, and it speaks English and Japanese.
One detail trips everyone up: events only show up after you set the Game Title in the app. If One Piece events are invisible, it's because the app still thinks you play something else. Switch the title to your game and they appear.
The new piece: TCG+ D
Decks were the missing link. You could register for a tournament, but there was no official place to build and file your list. TCG+ D fills that gap.
It's a web-based deck-building service that arrived in two waves this July. One Piece support was announced on July 10 and went live on July 31, 2026; the Gundam Card Game followed in late July (scheduled for the 27th). Being a web tool, it has no separate download — you add it to your home screen from a browser and it behaves like an app.
Beyond building decks, D lets you search cards and decklists, browse top-performing lists from Championships and other events, use match-support tools mid-game, and run a solo practice mode — what the Japanese notes call "一人回し," or playing against yourself to learn a deck. You can then link any deck you build over to TCG+, so your tournament registration carries your list with it.
Setting it up
Here's the short version of everything you need:
- Create a Bandai Namco ID. Since September 28, 2026, that ID also needs a home address added on the Bandai Namco ID website — you can't do it inside the app. Without it, you can't apply for new tournaments or use last-minute check-in.
- Download TCG+ and sign in with that ID.
- Set the Game Title field to your game so its events appear.
- For TCG+ D, open the deck builder in a browser and use Add to Home Screen (iOS Safari or Android Chrome both work).
Why it matters
The payoff is that your deck list and your tournament entry live in the same account. You build in D, hit register, and the list travels with you to the event — no retyping cards at the shop, no scrambling to resubmit a list you forgot on another device. It's a small thing until you're standing outside a store at 9 a.m. with one hand holding your deck and the other holding a phone, and it suddenly feels obvious.
For anyone new to sanctioned play, TCG+ turned the hardest part of entry — just getting signed up — into a five-minute task. Worth downloading before your next Flagship Battle or store tourney.
