I found this on the corner in front of my neighbor's gate.
This is to welcome the ancestors' spirit to this world.
In Japan, usually obon is around August 15. Many offices and factories are closed for Summer vacation so that people can visit their home town. August 15 and that week is also called obon yasumi(= obon holidays ) . This family must have set July 15 as Obon instead of August. The gap came from lunar calender basis or new calender basis. Anyways, around Obon , it is said that your ancestors visit you and the cucumber and egg plant ( in the left photo ) with legs like chopsticks are substitute horses ( or something they can ride on ) to come to this world. There are some dumplings and veggie basket as offerings.
