Typical of Tamiya kits in the last 30 years or so, this one is superbly molded with a fairly complete cockpit/crew area. The interior includes seats for both the pilot and gunner along with decals to put on the seats if you aren't going to use the included figures. There is good sidewall detailing and if you'd like to use decals for the main instrument panel, you can as those are provided as well. This is the angled upward cannon armed version so that item is included up to the barrel to place in the middle of the airframe where a fuel tank used to fit.

In order to allow both this earlier and the later III kai aircraft with the more streamlined nose, separate nose sections are provided, this being the 'shorter' one.  Unlike Hasegawa's 1/72 kit, the center section of the upper fuselage is not incorporated with the canopy piece. This is to allow the modeler to pose the many canopy sections open if so desired. There is no defensive rear gun in this one.

One builds up the gear wells trapping the landing gear legs in them before inserting these assemblies into the lower wing piece. It doesn't look like the gear can be added after painting, but test fitting will show one way or another. A short wing spar is provided to help stiffen this all. The kit can have bomb racks installed and so at this time those holes need to be opened. Attaching the wing to the fuselage looks pretty standard and from the looks of it, Tamiya wants you to prepaint it before attaching. I'll pass on that.

As mentioned there are air to air bombs that can be attached to the lower fuselage. Gear doors have 'hooked' hinge pieces to help with attachment. It is only now that the engines are built up. These have polycaps in the gear box to hold the prop/spinner combo. In this case there are options blades and spinners with one set being a bit more pointed than the other. There is no indication as to which marking option uses what so your choice. The engine is then attached to the firewall, which has the exhaust attached to the back of it and then the one piece cowling is glued on. These are handed so follow the instructions well. Last bits are the attaching the engines to the nacelles, adding the various guns and pitot tubes.

One option does not have the big gun sticking out of the roof, which makes me wonder about doing that one as you still have the rest of the gun assembly filling the rear. As mentioned, one can pose the various canopy pieces open if one wishes, though they are all shown closed. Instead of having six clear pieces it would have been nice to have just two for the closed position.

There are three markings options provided for you. All the upper surface and undersurface colors will need to be mixed as none of them were in the Tamiya catalog in 1997 and you are only provided Tamiya paint references. The box art plane is in brown over grey and was with the 17th Hikoki. The other two have green upper surfaces with one being with the 16th Hikoki and the other with the 29th Sentai. Decals are well done and printed by Scalemaster, which means you can use standard setting solutions on them. The sheet includes the yellow wing leading edge bands, though you may wish to paint these. The white wing and fuselage 'bandages' are also included on the sheet.
