Know that tournament is what the players want needs to go first
Currently, my l5r group is having winter court adventure. One of the highlights is the Bowman's Wager, a tournament that is in the universe giving the participants huge prestige by just taking part and the winners get prices that are quite extreme. Now, when the tournament started three players were present, all of them very invested in their characters and the world.
But if the players are not invested in the idea of a tournament: just go on, do something different.
Getting spots should be fun too
Just showing up for the tournament should not qualify in itself. There are countless of chances to make even enrollment fun for the players, and that allows a lot of participation of those that do not take part in the actual tournament. After all, a Dragoon wouldn't want to take part in a bowman's tournament, and a bowman that can't even ride has no chance to win in a classic bout of lancing.
To be in the Bowman's Wager, the characters need an invitation for one of the 25 sponsors - which in our case gave the characters that wanted to participate a means to intrigue for. Since one doesn't have archery as a skill and didn't even compete to get a placement in the tournament, this left two that pushed for their own sponsorships. The player not participating helped with checking up on some of the things to get the intrigues going and in general, it was a lot of social play to get two sponsors and also find out who was the competition before the actual tournament started - just to gauge how well they might compete. Of the NPCs, about 6-7 are quite well known to the characters, like, long-standing relations or very favorite NPCs because of quirks. So the whole round has an interest in their success or loss.
Taking part in the tournament should not be just a combat simulation
Combat simulation can be quite boring if some people can't take part. There's little excitement in just waiting for your turn to slog through the combat. Instead, consider a game for points - that is how the Bowman's Wager works and which worked well for us:
The first two rounds allow participants to score up to 10 points. Now, such a task accomplishing is handled as skill checks on the Kyujutsu skill with varying TNs in l5r-4e. Round 1 is simple, everybody rolled against the same TN and to cut down the number of rolls, each roll accounted for two points. In Round 2, the TN increased with each of the 5 targets hit, and the participant would score based on hits and unused arrows once all targets are hit.
The point is, that classic combat takes dozens of rolls for an outcome of "This one is eliminated" and stretches a long time without the players that don't have their turn doing something. Simplifying combat or using duel mechanics cuts down waiting time and boredom from it. By making the rolls for short, quantifiable goals that score on the board can make every single roll of a player an exciting thing: Is the archer scoring a 10 or a 9?
The scoreboard could be exciting in itself
After the players did their rolls scoring the points, the GM slowly filled in the participation roster at the center of the table with the scores of the others after rolling them. Comparing and finding out who came through fell to the players. We also figured out that we would need a tiebreaker between a number of NPCs that scored evenly to get the number of participants correct. While the numbers were filled in, there was anticipating tension around the table about which character would go on or drop out, and if a score would suffice for the next round. This was compounded by the fact that the players have their favorite NPCs they want to see succeed, and others they want to see fail. It felt like a betting parlor.
Don't exclude players not taking part
Now, tournaments eliminate players, some didn't even take part. So as a GM you should think about how to include those too.
In between the first two rounds, there was spotlight on the non-participating character, as he was tasked to write a report on the tournament. When the 2nd round eliminated it down to one player still in the race, we inserted a little filler to get everyone back together. In our case, it was a party with those others eliminated hosted by our favorite archer - the player still in the tournament.
Bonus option: Make those multiple arenas close enough to each other/linked to each other, such that things like spell effects might splash over between battlefields.
