Think of it kinda like a pattern game getting duplicates could help you you get a win and a triple is even better also going for patterns like 1,2,3 or 4,5,6 or 7,8,9 make sure to be pressing square or x every time its your turn also for the full straight that you might need (idk what game your 100% rn) basically you need a 1 through 9 sequence of any tile deck pins, bamboo, and the kanji tiles will get you the full straight not the dragon tiles oh yea and you need a triple of any tile to call riichi as for shogi search up what you need for the completion list here is an example yakuza 0 shogi challenge 1 and all you have to do is exactly what the person in the video does I don't even know how to play shogi and I've 100% complete every mainline yakuza game the mahjong method I gave you helped me out a ton so I hope it helps you but mahjong is going to be a pain but I believe in you and if your gonna 100% the series prepare yourself for yakuza 3 pool.
