You need to have found the HM Waterfall. It is found in Ice Path between Mahogany Town and Blackthorn City, there is a man with some glasses looking at it. Teach Waterfall to a Pokemon and use it to climb the waterfall in front of you in Tohjo Falls, follow the water round and fall down the next waterfall. Then you should continue along route 26
Use waterfall
Your game should not freeze trying to go through Tohjo falls. If it does, you might have a corrupted game and might have to buy another one. If you can, return it to the store with your receipt and get a new game.
If you have beaten/captured Ho-Oh, you go past Tohjo Falls and walk east.
There is no tohjo falls in fire red i think it is only available on pokemonn heartgold and soulsilver but u should check it on serebii.net
you need to get waterfall which can be found on the ice path from mahogany town to blackthorn city. :D aydelie 101
To get to Giovanni's secret cave, you must go into Tohjo Falls then go to the left waterfall and then if you see a cave behind the waterfall, go in it and that is Giovanni's SECRET cave.
Simple, defeat all gym leaders, find HM07 in ice cave (waterfall) learn it to your water pkmn and surf!
go 2 the right n just exit the 1st exit u c that thing is like an overly complicated maze

You cannot reach jhoto in leafgreen because the tohjo falls are not in the game.
It's in the cave on the route east of new bark. Just surf there!
you find out in the celebi event, but it deals with Giovanni.
Yes, on the way to Kanto on Foot, you will need to travel up Tohjo Falls. Hope i Helped.
