Hey, I was told that foreigners are organic etc. fans :) Seriously, chlorine, ammonia, formaldehyde and other non-Greanpeace stuff, alone or mixed, will disinfect the lenses and definitely PREVENT fungi to grow, but they couldn't remove the fungus (or remove them with lens coating). The only way is to remove fungus by enzymes (protease, amylase and lysocim), naturally :) I don't know about availability of pure enzymes in countries outside Russia (I mean off-the-counter drugstores), but it seems you can use cleaning tablets for contact lenses (=protease), dissolved in your own saliva (=amylase+lysocim). Mix tablests with your spittle until the cream/gel will be formed, then spread it on the lens and leave for 30 min (prevent from the dessication - put them to wet warm atmosphere in closed jar etc.) Thn remove the spittle with soft tissue, spread another portion of mixture and remove the fungus with the same tissue by gently wiping of target zones - fungi became soft and easily to remove. If fungus is still scratch-resistant, use your finger. After removing the fungus, wash the lens with water and pure wine alcohol (or ether) and mount it back to the lens barrel. Fungi from Japan seems to be more exotic (=resistant), so you should leave the lens smeared with the "enzyme misture" up to 2 days (preserving from dessication, of course). However, cleaning of the single lenses appear to be easier then the glued ones. Good luck and feel back to nature! :)
Old lens case with fungus- trash?
