在廚房注意； 最後用完注意垃圾和油

Don't pour leftover cooking oil down the zink!
The pipes in Japan are very narrow and pouring oil down it will ealisy clog it up. Instead use ''固めるテンプル'', it will harden the oil so you can through it in the garbage.

You will have to call a Plummer if it gets clogged nd you have to pay a lot of money for it so it's better to try and prevent it!
