I plan to travel to Japan for a month during the college holiday. How much money should I bring?

If you don't shop in an ordinary hotel, 30 thousand is enough, which is about 600 thousand yen for round-trip air tickets, 50 thousand to 70 thousand, 6000 to 8000 for accommodation, transportation and food 10000. Shopping doesn't actually cost that much, so you shouldn't go out for 30 days. Some snacks cost 23,000 yen a day.
