In the morning, after my daily routine, ordered drain washer set for my Hunter Cub on on the net. 
The price was only 350 yen, included transportation cost Cheap!
The set contaions 10 washers. Good!
Along the way, the lamp of the bathroom didn't work well.
So tried to take the lamp off from the light unit, but couldn't. No way!
So went out for the DIY store to order to fix it. Along the way, bought a bottle of engine oil for my Hunter Cub.
In the afternoon, went out for a shopping mall to tale a haircut at this QB House, by 1,250 yen. Reasonable.
Along the way, found a good watermelon which price was over 5,000 yen. No way!
In the evening, a man came to see the bathroom lamp, and he hook it off. Great!
And we cleaned the unit. He will fix it within an week or so.
Well, that's about it.
