The pass is indispensable for travel in Japan. These passes cost 28,300 JPY for 7 days, 45,100 JPY for 14 days, and 57,700 JPY for 21 days. All pass times are for consecutive travel. Even if you just get the seven-day pass, it's the same price as a round-trip train ticket from Osaka to Tokyo (14,250 JPY each way!).
