Based on that amount of money, and that you have two dependents, you will probably pay less than 10% including social insurance, and health.

Will the company also pay for gas, electricity, water, etc in the accommodation?

No, company will not pay gas, electricity, water, etc in the accommodation,

Also can you tell me what an insurance fee for accommodation as it is there in my offer letter.

The health insurance will be paid by my company but nothing return about social insurance.
Can you please clarify all that Also for my monthly salary how much amount i need to pay as tax ?

in my offer it is like -

1. 4184400 Yen Gross Salary per year
2 0 to 20% of Gross Variable per year
(Performance base )

3 Tax:-
a. Statutory Tax and Social
Insurance Tax will be
deducted from my monthly
salary,

b. Total Tax to Japanese
Govt will be around 15%
Can anyone advise How ok it is ?

That sounds fairly normal to me. The insurance fee for accommodation is probably in case there is a fire or serious damage to the apartment while you are staying in it and is also normal.
