Yes, it is important to make money it is also important to save it as well. When you accept an offer for a position, it is important to live in the city you work in or close to It. The longer you train ride, the more stress you have worrying if your train will be delayed or you have to wake up much earlier than you want to. If moving is not an option or you have to ride the train, I suggest you buy a monthly train pass.
If you are going to the same school every day, the train pass can be from your home to the nearest train station. If you are going to multiple schools with different stations, find the closest station to all the schools. The price difference will automatically be calculated. Not only that, your train pass can be used on Saturdays and Sundays. Any train stops between those schools will be absolutely free!!
You can buy for 1 month 3 or 6 months. The longer the pass the cheaper the daily rate will be.
If you are not sure how to get one, here are the words in Japanese: 😏 Sumimasen, Teiki ken wo kaitai desu. Oshiete kudasai. English Translation: Excuse me Please show me how to buy a ticket pass 🎫
Good luck. If you have problems let me know.
