why rakuten is so slow? anyone having the same issue?

im literally in the center of the tokyo and got 23.50mbps download and 5.68mbps and it's not even stable, regretting switching from ymobile, this 2k yen difference isn't worth it for the ones who wants to change their provider to rakuten because it's cheap. anyone also having the same issue or is it really just me i didn't saw any bad comments about rakuten recently
