Big question mark had been floating above my head. There are the situation which I can’t define the meaning, unreadable. I’ve been learning about the world since thirty years, I thought I know most of things I see on the street, at lease in my country… I’ve been passing by that place on the way to go working and to home. At that place, at the side of street, there are a planter with 4 wheels at the bottom, the plant in the planter looks like vegetable and has a tag with the date. The planter is changed every day to other one (vegetable inside become smaller or bigger) and has different date on the tag. One day I notice, at the other side of the street, there are about 10 planters on a line and covered with frames with net.The date on each tag shows there are 5 day different, like 04/15, 04/20, 04/25… there are some empty planter with the coming date. In front of those planter the soil in square trays are prepared. I’ve been wondering what kind of study he is doing?? Are there more planters somewhere? Where is the planter of last year? I went to him very straight when I saw him on the way to home yesterday. He was working with soil in the tray. I really had to ask him what he is doing. Otherwise, i had to be suffered by my big question mark hanging on my head. So, his story was like this; he is raising the vegetable to eat. It takes about five days to eat the vegetable in a planter, so he doesn’t need to waste and ran out, either. He does this work, otherwise he doesn’t have anything to do. He watched on TV that he could raise the vegetable in the planter, and he had been doing this already since four years. He goes zoo every Saturday to get the elephant’s shit for vegetables. (The zoo is distributing the bag of muck to the people every Saturday, at 2 o’clock.) The frame with net can protect bugs. He is just disinfect the soil by sunlight. He fix the wheels because he can move the planter to other side of street easily to get more sunlight for vegetable. He raises Mizuna (potherb mustard) and Komatsuna (Japanese Mustard Spinach) alternately. It takes a months to be ready to eat in summer time and two months in winter time. He gave some Mizuna to me. I told him I’ve been watching his vegetable and eager to know the person who was doing this and reason. I cooked salad of Mizuna and ate. The most fresh Mizuna I ever ate…
