Well, since G4 has finally (I think) aired the 19th competition stateside and people keep ending up here on google searches here are some photos of the first stage of the latest SASUKE competition:
Stage One obstacles:
1. Sextuple step 六段跳び
2．Log Grip ロッググリップ
3. Pole Maze ポールメイズ
4. Jumping Spider ジャンピングスパイダー
5. Half-Pipe Attack ハーフパイプアタック
6. Warped Wall そり立つ壁
7. Flying Chute フライングシュート
8. Tarzan Rope/Rope Ladder ターザンロープ/ロープラダー
Now then, to address some other searches:
Colin Bell and Brett Sims were the two representatives from G4 from America
Unfortunately, while they did well (especially relative to the rest of the field), they couldn't get past the first stage.
