If you plan to buy JR Pass for your journey, you may need to take note that the nearest train station from this homestay is shin egota station. To reach here nand to go off from here, you have to pay extra for taking train from shin egota to other places before you can use your JR Pass, because Oedo line in shin egota is not covered by JR Pass. You may need to take train until higashi nakano station, then change to JR train there. based on my experince, this is the minimum fare you need to pay (180yen), but you need to transit one more time if you want to go to places like shinjuku. if you do feel troublesome to transit so many times and do not mind to pay a little bit more, there is another option to take the train from shin egota to shinjuku by paying 220yen. family mart is just a stone throw.
