The inside of the lockers are nothing fancy. They are two-shelved, with the top one being for your outdoor shoes and the bottom one being for your indoor shoes. (I think… Everyone does it differently so I’m still confused.)
The gray shoes are my indoor shoes. I got them from Walmart for like $5. The Doc Martins are my outdoor shoes, that I wear basically every day. The blue thing is my shoe bag that I brought my shoes to school in the first day. But since I decided to just buy two pairs of shoes instead of carrying one pair between my different schools, there was no need for the shoe bag, which is why it’s just kind of there.
To the side of the lockers is the reception area. Behind those windows is the “jimushitsu” or the office room/place you can get supplies from. The inside workers are kind of like secretaries, and they handle a lot of the day to day business of the school.
Actually, my first school didn’t have a greeting area like that. The faculty entrance was right next to where the third years put their shoes, a layout that I haven’t seen since. Usually, the students come in through a different entrance. However the case, there will always be a genkan area and there will always be a place to put your shoes!
