I'm planning to travel from Nagoya Station to Himeji Castle with 2 luggage After that,I'm going to hotel Kobe station. Are you aware that you can stop by Kobe on your way to Himeji?
Where is your Kobe hotel?
Have you asked the hotel staff whether they can keep your luggage before your check-in?
In Kobe City there seems to be, near Kobe-Sannomiya Station of Hankyu, a secondhand suitcase shop who offers a cloak room service to travelers for suitcases or other traveling bags.

http://www.rentaclaus.com/index_azukari.html: On this website, no description of a specific date is found; it sounds better to contact the staff in advance, for up-to-date information.
: Sannomiya is not served by Shinkansen. You can get off your Shinkansen train at Shin-Osaka Station, pass through Shinkansen Transfer Gate then catch a westbound Special Rapid train on the JR Kobe Line, which arrives to Sannomiya Station in around 25 minutes.
: In the vicinity there are six railway stations whose name includes the place name Sannomiya, including Kobe-Sannomiya Stations of Hankyu and of Hanshin. Please feel free to ask a station attendant how to find your way.
The walking route from (JR) Himeji Station to Himeji Castle Park is mostly paved and relatively flat.
Once you get into the castle, however, you walk up on a pebbly unpaved sloping road to the dungeon.
On the north side of (JR) Himeji Station, where Himeji Castle is,
there is a facility (set up by Himeji City) for bicycle rental and cloak room services on the 1st floor (= ground floor) of Shinki Building, which is to the south of Sanyo Department Store;
however, it is not clear how the upper size limit is.
