My son is about to graduate, and his school trousers have become too small. I panicked and bought a new pair, but I made a mistake with the size. I tried to lengthen the hem, but it was too short, so I gave up. I bought them for 6600 yen. The hem is still lengthened, but if anyone is interested in using hem tape from a 100-yen shop or similar, please consider purchasing them. They are unused, but have been stored at home, so please refrain from purchasing if you are concerned.
