So I moved to Japan 2 weeks ago and have been biking on a Mamachari. Today, I decided to pump up one of the tires not knowing how the valve worked. I unscrewed the bolt-looking part and a ton of air shot and the pieces went flying out. I found them and attempted to put them back in, but no air held in the tire. The tire shouldn’t be damaged at all, so I think its just the valve. Any ideas on what I can do?

Probably just need to replace the smart rubber tube on the valve piece. Can buy from 100¥ shop
The piece (bolt looking part as you said) to the upper right of your hand in the second picture needs to be screwed on over the valve.
Also, make sure you’re using the correct adapter for the valve. See [here](https://www.cyclescheme.co.uk/community/how-to/how-to-use-tyre-valves).
Most bicycles in Japan use an English valve (aka Woods valve / Dunlop valve).
If you do a quick google search for it, you should be able to find pictures that will help you figure out if you’re missing any parts, and/or how to put it all back together.
If all else fails, you can usually find a replacement valve at a 100-yen shop; or just bring it into a nearby bicycle shop.
The photo of the valve piece is focused on that bugger on the floor
