As the Japanese are reduced to a marginal interest group in their own country, even their laws will not be safe from immigrant protests. First, they will be lobbied, bullied, and shamed into accepting their new feminist laws. Women will get preferential treatment in all areas of employment, until there are no more suitable men that out-earn them, and the men will be reduced to shit-tier service sector labour, and involuntary, depression induced NEETdom. Next, they will start writing their legislation in multiple languages; to show the inclusive nature of the state, and to welcome the new Japanese to their tolerant new home. This is just the beginning though, eventually, once the Japanese population becomes the minority, the language of legislation will be converted to the most inclusive, universal, and progressive language of all: English. By this point there will be nothing unique left of the Japanese. They will be lonely and depressed, they won't have kids, and the remaining children will either be atomized, isolated men, or globalized, booty bouncing, diversity loving thots, desperate to improve their status by dating the biggest, strongest, urban beast they could find.
This is the future of Japan. Just sit back, relax, and enjoy the collapse.
