Tons of weird gel stuff here. Powerbar, Weider, Wasp, Meitan, High-5, Musashino, etc. I haven't seen 'GU' in particular ... Actually Japan has something no other country in the world does, though. CONBINI! Why carry all this junk around when you can stop into any CONBINI and load up on REAL JAPANESE RIDING FUEL:
- Tuna Mayo Onigiri - Yaki Imo - Lychee Salt Drink - Boss Liquid Crack - A billion kinds of Unkon and Super Salaryman Drinks - A thousand (at least) Jellies, Custards and other stuff - REAL GOLD - Black Thunder - Honey 'sticks'
Plus , most of the roads have vending machines with plenty of selections of liquid octane boosters, crack-in-a-can, water, sports drink, etc.
PM FarEast. He is the Japan representative of High5 sports gels and supplements They have the best flavor out of anything I have tried and James(FarEast) knows the science behind them. They are all natural.
