The subway/taxi method is worth considering if I can use a day pass on the subwayThe subway pass is valid only until Akaike Station. You will have to pay a supplement of 500 Yen for the Meitetsu Toyota Line portion of the journey.
as the taxi fare is more expensive from Toyota Shi station than from Tsutihashi stationYes, Toyota-shi is a little bit farther away than Tsuchihashi Station. The bus takes 15 minutes for the trip, so you can assume that the taxi will require between 10 and 15 minutes. My guess is that the taxi fare will be about 1500 to 2000 Yen. The bus fare is 290 Yen.
If you want to be at the Toyota Kaikan by 10am, I recommend the following itinerary (assuming you go on a weekday):
8:29 depart Fushimi Station by Tsurumai Subway Line
9:16 arrive at Toyota-shi Station
19 minutes to find the correct bus stop (you could take one subway later, but then you would have only 7 minutes to find the bus stop, which may or may not be enough time to find your bus).
9:35 depart by bus bound for Toyota Kinen Byoin
9:51 arrive in front of the Toyota Kaikan
There are also bus departures at 9:05 and 10:05 (every 30 minutes).
You can look up the train schedules by yourself here:
http://www.jorudan.co.jp/english/norikae/I imagine the Toyota Shi station is a major stopping point so I won't have trouble finding the destination but is it diffuclt to find the number 4 bus stop at Toyota Kaikan going in the right direction?Yes, I had troubles finding the bus stop. If you leave Toyota-shi Station through the west exit, you will get onto a spacious, elevated pedestrian plaza. The bus stops are on the street level below the elevated plaza. Here is a map (your train will approach Toyotashi Station from the north):
http://trainbus.meitetsu.co.jp/bus/noriba_toyota.htmlAs you know, your bus leaves from bus stop #4. I think the signs at the bus stop and on the buses are in Japanese only, so if you don't read Japanese, you might want to make sure with the bus driver or other passengers.
