Sakamoto Days Sleepy Straps Are Here—And AmiAmi’s Exclusive Kamihate Badge Is the Real Dream

The new Sakamoto Days “Oyasumi Acrylic Strap” set is officially up for pre-order, featuring all-new sleepy-time illustrations and a must-have AmiAmi-exclusive badge starring the ever-mysterious Kamihate. If you’ve ever wanted to tuck your favorite assassins into bed—this is your chance.

This adorable yet deadly merch drop comes courtesy of Sakamoto Days, with manufacturing by Sol International and distribution via hobby megastore AmiAmi.

Acrylic straps feature six fan-favorite characters in their bedtime best—complete with tiny futon covers. Each charm includes both a sleeping pose and a mini blanket, all newly illustrated just for this release.

Buy a full box (6 straps) and you’ll get a guaranteed full set. Oh, and did we mention the exclusive bonus?

🎁 AmiAmi’s Box Bonus: An exclusive 56mm badge featuring Kamihate, the one-eyed, cold-blooded charmer of the crew.

Releasing in July 2025, but pre-orders are already live. Blink and you might miss them.

Only available on AmiAmi’s official online shop and in-store branches. No word yet on overseas distribution, so international fans may want to act fast (or make friends in Japan 👀).

Because who wouldn’t want a snoozing Sakamoto dangling from their bag? Plus, the exclusive badge sweetens the deal, making this set more than just another merch drop—it’s a collector’s gem.

Fans of Kamihate, in particular, will find this extra tempting: it’s not every day he gets the spotlight, let alone in cozy mode.

Pre-order the 6-piece box (¥5,280) or try your luck with individual straps (¥880 each). Each charm is acrylic, with a PVC futon cover, plus strap and clip included. Perfect for decorating your keys, bags, or just… admiring lovingly from your desk.


Don’t sleep on this release—literally.
Head over to AmiAmi’s product page to pre-order your full set and grab that Kamihate badge while supplies last.

And remember: the early bird gets the… sleepy assassin strap.
