There is still a little more than a month to the release of the Nintendo Switch, but you might already be thinking about planning your shelf space. If that's the case, don't worry, we're here to help.

The biggest Japanese gaming stores are starting to display Nintendo Switch game boxes (empty for the moment), including the ultra-popular Yodobashi Camera mega-store in Akihabara, and I happened to be there today.

To give you a good idea of how big the game boxes are, I started taking comparison screenshots with a Wii U box, and since no one appeared to be interested in stopping the strange big gaijin carrying boxes from the various aisles to the Nintendo Switch one, I went all the way and compared the new cases against those for 3DS, PS4, Xbox One, PS Vita, PS3, and PSP.

As you can see in the gallery at the bottom of the post, Nintendo Switch boxes are considerably smaller than Wii U ones, basically as tall as PS4 and Xbox One cases, but thinner and in both width and depth.

They're exactly as wide as PS Vita cases, but taller and a bit thinner, and last but not least, their front face size is almost identical to PSP cases (just slightly shorter in height).

Unfortunately, I couldn't make a good comparison with Xbox 360 boxes, because in the whole store there wasn't one outside of anti-theft cases (as if anyone would steal an Xbox 360 game... in Japan).

As a bonus, you can also see the front, back and interior of the boxes for The Legend of Zelda: Breath of the Wild, Nobunaga's Ambition: Sphere of influence, Romance of the Three Kingdom XIII, 1-2-Switch, Super Bomberman R, Disgaea 5, Puyo Puyo Tetris, I Am Setsuna, and Dragon Quest Heroes I-II for Nintendo Switch.

Interesting, Puyo Puyo Tetris doesn't have a printed interior, while not all games warn how many megabytes of internal storage are required (presumably for save games). I Am Setsuna requires 50, while  Dragon Quest Heroes I-II for Nintendo Switch requires only 11 megabytes.
