Need Help To Translate Japan Postal History Item From Russo Japanese War

Hello, Here is one Japan postal history item from Russo - Japanese War era in october 1904. Perhaps someone can help me to translate where this card was sent from and post offices where card was cancelled? It is hard to recognize this item without japanese language. I know that these postal stationery cards were used during Russo - Japanese War period.

Thank you for your help.

I used IA and this is the result:

Cancelled in: Japan, March 1942 (Sh#333;wa 17-3-21), likely from a military unit or battlefield.

Received in: Tokyo, Sugamo Ward (#35914;#23798;#21306;#24035;#40232;), Toshima District.

"Dear [Inaguma Sakutaro], I hope you and your family are well at home. Here [at the front/where I am] everything is fine for the moment. The weather is [cold/hot] and we are making progress. Please take good care of yourselves. I send you my best wishes. Sincerely,
[Sender's name – appears to be a male name, difficult to decipher]"

I hope this helps!
Regards,
Rodolfo
