I’ve only ever used the same pumps as for my Prestas. No adapters, no problem. The tips of the valves where they engage the pump are close enough in diameter.

And just like on Prestas, the valve cap can be permanently left off with minimal consequences.

Yeah, that type of valve core wasn’t much fun. Mostly b/c it created a lot of resistance while inflating. Plastic hand pumps could get warm enough to start deforming.
Over here, we have these:
We’d call them ”speed valves”, or ”flash valves” due to how much faster inflation went.
If Japan really haven’t discovered these, there might be a business opportunity there for you.
It’s the exact same fit as the tubed valve cores and with the longevity and flow characteristics like Prestas.
