Right, where to begin?
Well, Dekana covered the basics, but the minimum you'll need is:
Superglue
A metal file
A palette for your paint
Brushes
2 Paper cups for water
Paint
Bases
Models
A set of clippers and a sharp knife may also be handy.
If you have a Daiso or other 100 Yen shop nearby, you should be able to find a set of mixing palettes and paper cups easily enough. You may also be able to buy brushes there, though they aren't much good. A cheap 100 Yen brush does have some uses though, so it may be worth picking one up.
Superglue can be found in most convenience stores. Look for a product called Alon Alpha, (in katakana) it should be in a yellow tube. There will be pictures on the packet telling you which materials it is good for.
When it comes to gluing things together, use Polystyrene Cement for plastics, PVA for wood and Superglue for metal and resin figures. If in doubt, or mixing materials, use Superglue.
It seems like you already have models, so let's look at bases. There are a few options.
Coins are a fairly easy source of bases. English 2p or Japanese 5 Yen coins are cheap and give your model some heft to keep them on the table. You will need to do more work to cover them up though.
Plastic bases are the most common, though not easy to source in Nagoya. You can order some from
http://www.ring-tail.com/shop-category.php?La=E&Cat=88 in Kyushu. (Also take a look at the section for Renedra bases). The shop owner is very helpful and speaks some English. Presuming you bought Perrys models, you'll be needing 25-30mm bases. The convention is to use round bases for skirmish games and square bases for big battles (because they are easier to line up). Ordering from overseas also provides some more options.
The final choice is to use MDF bases, these are usually available from companies that make terrain.
https://www.sarissa-precision.com
and
https://www.4ground.co.uk
both offer bases. Sarissa makes unpainted terrain with a lot of Japanese buildings and is the cheaper of the two. 4ground has cheaper bases, some pre-painted Japanese buildings, but they cost a little more.
For tools, these can be found in Nagoya.
If you go to Kamimaezu/Osu, all the hobby stores are in the same place. I think exit 10 at Kamimaezu station is the closest. There are three shops to look for:
Joshin Kids Land - They have a range of modelling tools and brushes as well as some Tamiya paints.
Hobby Shop Volks - Again a range of tools, but they sell Vallejo paints.
Yellow Submarine - Mainly a board/card game shop, but they sell Games Workshop paints.
The webshop above also sells a few brands of paints and some Games Workshop hobby tools. The GW tools are crazy expensive though. If you want to save time and hassle,
http://www.ring-tail.com/shop-descripti ... 1325800019 might be a good choice.
For the file, you're looking for one that looks like a long, thin iron bar covered in ridges, somewhere around the size of a paintbrush. If it looks like something you'd tidy up your fingernails with, it's a waste of money.
A couple of brushes from Joshin should set you back a few hundred yen. They're not the best quality, but so long as you keep them clean they'll do the job for now. You want brushes with a sharp point on the tip. If memory serves, in Joshin you should look for black handled brushes with a size of O and OO. That should cover you for regular and fine detail work.
Finally, paint. There are lots of brands, but let's go over the ones easily available in Nagoya.
Tamiya and Mr. Hobby are Japanese brands. They have their uses and do make some good products, but I have generally had poor experiences with them. Their spray on Primers are good though.
Games Workshop/Citadel Colour is made for wargaming. The colours are usually bright and vivid, give good coverage and they make some good tutorial videos as well. They are a little pricey, but worth it. Picking up one of their starter sets from Yellow Submarine should give you the essentials and some basic colours to work with. Citadel brushes are pretty good too. Their spray on Primers are again quite pricey, but good.
Vallejo paints give you 50 shades of everything and are my go-to brand when it comes to painting. The Vallejo Model Colour range is great for historical minis with realistic shades of browns, greens, khakis and greys. Game Colour is more vivid and similar to Games Workshop. Model Air is for airbrushes only, so you can ignore it. They also do a great range of technical paints for adding mud splatter, texture and other unique effects. After picking up basic colours from either Citadel or Vallejo Game, augment your collection with Vallejo Model Colours. Vallejo paints often separate in the bottle, so shaking them thoroughly before use is essential. The dropper style bottles let you control how much paint you use in your palette and help avoid spillage. Sometimes an air bubble will form in the neck of the bottle and cause paint to spurt out when you open the lid, so be sure to tap the base of the bottle on your desk a few times before opening.
For metal figures, varnish is essential!! You can get this as a spray or a brush on type. The spray type is quick and easy, but will sometimes turn all misty on you and ruin your model. The brush on type takes longer, but gives you more control and I've never had any misting issues. Vallejo Matt Varnish is my usual choice, though Citadel makes one as well.
To break it down, you need:
Spray on Primer. Usually Black, Grey or White. The primer helps the paint adhere to the model. The colour of Primer has an effect on the following coats, with White giving a brighter end effect and Black a darker one. Black is more forgiving if you miss a spot though. White spots stand out a mile.
Basic Colours - White, Black, Red, Blue, Yellow, Green, Brown, Metallic Silver. These should give you a range of options when mixed together.
Other Essential Colours:
Skin - This is one of the hardest colours to find a good choice for. I nearly always end up mixing a few different skintones together. Vallejo Heavy Skintone is the closest I've found for straight-from-the-bottle painting.
Gold - Because sometimes models have a bit of bling.
Light Grey and Dark Grey - White and Black are hard colours to shade, I find greys are easier to work with.
Beige - A very useful colour for those odd bits of clothing. Vallejo does one called German Camo Beige and I use it all the time for socks, shirts, hats etc.
Washes - These are special paints designed to cover a model and flow into all the nooks and crannies. Brown is pretty much mandatory for most things. Black is good for metal and steel. Citadel has one called Fleshshade which is great for adding depth to skin.
Varnish - As mentioned above. If you don't want to repaint your figures after every game, get varnish.
