Good source for KHK certified pony cylinders in Japan?

[afieldofblue]

Hello all,
Would anyone know a good source for KHK-certified pony cylinders in Japan? I can find normal tanks, but have issues finding pony tanks - looking for for something in the 3L range, or AL13 to AL19, depending on what's available.

They're easy to find online abroad, but these won't be KHK certified (tanks in Japan must comply with the High Pressure Gas Safety Act, which requires them to bear the KHK - Kōatsu Gasu Hoan Kyōkai - stamp. Tanks without this stamp cannot be legally filled or used in the country).
I did find some second hand ones (KHK AL19), but would like to check out prices on new ones as well

Thanks!

The only big importer of ALU tanks is Aqualung Japan.... and they mainly do AL80s and AL40s.... never heard about smaller ones. There are no companies in Japan that makes them so need to impart 40-80 of them and then get them certified. Would love to know this as well !

So I'm not the only one, thanks!
Is it complicated to get a tank KHK certified? I've never owned tanks here in Japan, so haven't really looked in hydro facilities etc
If I were to buy a DOT pony and get a Japanese hydro, what would be the process, if this is at all possible?

My main issue is buying a pony then not being able to get it filled or hydro'ed when the time comes. I'm guessing this applies to valves as well, right?
