In the Japanese Diet (or at least in its upper chamber) you can perform a kind of filibuster known as a 牛歩 (gyūho), or "ox walk", by walking SUPER SLOWLY (like an ox) to cast your vote.
I'm not 100% on Diet rules. However, I'm pretty sure that you can do it so long as you don't stop or walk in a way that shows you're obviously not trying to reach the booth; though again, no expert.
Anyway, is this kind of filibuster unique to Japan? Or is possible in other parliaments as well? And if it is unique to Japan, what parliamentary procedural differences does the Japanese Diet have that others don't?
