Developing Pieces and General Opening Strategy

Are you supposed to develop pieces in shogi as in chess, or should you try to protect your king as much as possible first or try to perform a tactical blitz? I heard that shogi is more tactical than chess, but I don't know if that means you should try to be tactical right from the beginning. Is it bad to develop pieces too much because they block the rook in the second row? I was kind of feeling that in some games. Are there serious weak spots in the initial position that you should pay close attention to at the beginning like f2 and f7 in chess?

Please listen below as who write it is lishogiR1600 lichessR1500 person.
The word "tactical" (vs strategical?) is too difficult for me so I skip it, sorry.
There are weak spot like f2 in shogi. It's 23 and 87 pawn (in front of bishops).
When game starts, no piece defends there.
Of course 43 53 63 and 47 57 67 pawns are not protected though, they can be easily protected (i.e. 58 gold and 48 silver and so)
23 and 87 are weak because it is hard to protect (you can 78 gold, but how to make it be more safe?)
All shogi games are somewhat about those weak points.
Especially Bogin (climbing silver) is the most straightforwardly attacking weak point strategy, and often recommended to beginner because of its strength and easily.
However you shouldn't think Bogin as shogi scholars mate. It's so established strategy that even pro use it.

Also I should talk about bishop. All shogi games are also about bishop to some extent.
It's too strong that we should protect it but protecting bishop is hard because it's weak for pawns.
76 34 66 opening is not bad movement because it avoids exchanging bishop and enable protecting bishop like 67 silver.
After exchanging, we should careful about opponent putting bishop in our territory and it's hard task even for pros.

Feel free to ask further questions. Thanks!

Explaining the words:
Tactical -- 戦術・読み・手筋が大事。Tactics/calculation/tesuji are important.
Strategical -- 「戦略」・全局の感覚が大事。Strategy/whole-board intuition are important.

In shogi, generally you want to get your king safe before attacking, because once the fighting starts, you'll have no time to construct any sort of defence.

As you've discovered, the rook doesn't really have horizontal mobility in your own camp. That's why in the opening phase, the position of your rook decides the direction of your own development and of the middlegame. You can choose between between ranging rook strategies (put the rook somewhere on your left, or on the middle file) or static rook strategies (leave your rook on your right side).

Once you decide where you want your rook, you generally want to put your king on the opposite side of the board (so that they can't both be attacked at once), and build him some protection - usually with both golds and a silver. This is referred to as castling (different from chess castling).

Of course while doing all this you have to respond to any threats/tactics your opponent might be making, but this is a general, safe plan for the opening phase.

And if you're familiar with chess, try not to develop your knights too fast. They're best developed later as they can be vulnerable if advanced too quickly.
