Like someone mentioned, those Falcam setups get bulky fast and they're pretty expensive too. Tbh, if you're traveling to Japan, you'll want to keep your footprint small and your wallet happy. I usually avoid those ecosystem traps where you have to buy specific proprietary plates for everything... it just adds up way too quickly. I've been using the SmallRig Cage for Sony Alpha 7C II / 7CR 4422 and it's basically the standard for a reason. It's cheap, fits tight, and the grip area is still accessible enough for smaller hands. It has the Arca-Swiss base built in, so it goes right onto something like a DJI RS 3 Mini 3-Axis Gimbal without needing extra plates. That saves you weight and a few bucks right there. For your top handle and mic, I'd just go with something like the SmallRig Lightweight Top Handle with Cold Shoe Mount 2949. It's one of their cheapest handles but it's sturdy enough for an a7C II setup. If you're really trying to stay low profile and find the cage is still too much, you could even skip the full cage and just get the SmallRig Bottom Mount Plate for Sony Alpha 7C II / 7CR 4424. You won't be able to mount a top handle that way, but it keeps the camera tiny. Street shooting is all about being fast, and having less bulk usually helps with that... just something to think about before you drop too much cash.

Kyoto was amazing last year and honestly, a full cage was way too much for street stuff! i ended up loving the Tilta Sony a7C II Half Camera Cage Lightweight Black because it is super minimal. This setup keeps the grip feeling exactly how Sony intended. Save your money for sushi and grab a half cage instead! Its the ultimate stealth setup for Japan, trust me!

Honestly, be careful with that Falcam setup if you have smaller hands. I've measured the F22 plates and they add about 10-12mm of width to the grip area. That might not sound like much on paper, but it completely changes the center of gravity and makes the camera feel way chunkier than it needs to be. For street video in Japan, you're gonna want to keep that profile as slim as possible to avoid drawing attention. I would suggest looking into the SmallRig Half Cage for Sony Alpha 7C II / 7CR 4423 instead. It gives you the mounting points you need for a handle and a mic on the left side but leaves the right-hand grip completely stock. This is usually the best bet for ergonomics when using a compact body. If you absolutely need a full cage for protection, SmallRig Cage for Sony Alpha 7C II / Alpha 7CR 4422 is decent, but make sure to check if your fingers can still reach the front dial comfortably. Regarding the foldable option, specifically the SmallRig Foldable Cage for Sony Alpha 7C II / 7CR 4438, be aware that the hinge mechanism might introduce a slight bit of flex if you're mounting a heavy top handle and a monitor. I'd stick to a rigid frame if you're planning on doing any high-intensity shooting. Pair it with a SmallRig NATO Top Handle 3766 for a quick-release solution that isn't as bulky as the Falcam stuff. Just keep it light tho, otherwise you'll regret the weight halfway through your trip.
